When people hear about Fraxel lasers, it’s easy to assume they all work the same way, but the 1550 and 1927 wavelengths actually treat the skin in very different depths. The 1550 option reaches the deeper layers of the dermis, making it suitable for issues like acne scarring, etched lines, and long-term texture concerns.
The 1927 wavelength stays much closer to the surface, which is why it’s often chosen for pigmentation, sun damage, and overall brightening. A clearer picture of how these two wavelengths behave can make choosing the right treatment far less confusing.
Each one has its strengths, and the best match depends entirely on the type of concern you’re hoping to improve. With a little understanding of what each wavelength is designed to target, the path toward the right Fraxel treatment becomes much easier to navigate.

Understanding Fraxel Dual: The 1550nm vs 1927nm Wavelengths
Fractional laser technology represents a significant advancement in the field of skin rejuvenation and treatment. This approach allows precise targeting of skin imperfections while maintaining the integrity of surrounding healthy tissue.
The technology includes both ablative and non-ablative systems, with non-ablative options such as the Thulium 1927nm laser and Fraxel Dual offering a safer method for controlled skin resurfacing with minimal downtime.
How Fractional Laser Technology Works
Fractional laser technology is built on the principle of treating only a fraction of the skin at a time, creating controlled microthermal zones while leaving surrounding tissue intact. During a Fraxel laser treatment, the device emits a grid of microscopic beams that penetrate the surface, reaching precise depths within the skin cells.
These micro-injuries stimulate collagen and elastin production, essential for repairing fine lines and wrinkles and improving overall texture. By targeting specific treatment areas while preserving nearby skin, fractional delivery accelerates the body’s natural healing process.
This controlled regeneration reduces downtime compared to fully ablative lasers and provides long-term improvement for wrinkles and scars, sun damage, and uneven pigmentation.
The Science Behind Non-Ablative Laser Resurfacing
Non-ablative lasers, such as those used in the Fraxel Dual laser and Fraxel Dual Restore systems, work beneath the skin’s surface without removing the epidermis. Instead, they deliver heat energy to the dermal layer, encouraging collagen remodelling and promoting the growth of new, healthy skin cells.
This approach is highly effective for smoothing lines and wrinkles while maintaining the integrity of the skin barrier. Because non-ablative treatments don’t break the surface, patients experience faster recovery and minimal risk of infection.
With proper skin care after treatment, including hydration and daily protection using SPF 30 or higher, you can safely return to regular routines within days. Avoiding direct sun exposure post-treatment helps preserve results and reduces the risk of pigmentation changes or long-term damage such as skin cancer.
Why Fraxel Uses Two Wavelengths Instead of One (The Dual Concept)
The Fraxel Dual laser operates using two distinct wavelengths, 1550nm and 1927nm, each targeting different skin layers and concerns. The 1550nm wavelength penetrates deeper into the dermis to stimulate collagen growth and repair structural damage from wrinkles and scars, while the 1927nm wavelength focuses on the epidermis to improve tone, texture, and superficial pigmentation.
This dual treatment concept allows dermatologists to address multiple issues in one session, from deep fine lines and wrinkles to surface-level sunspots or roughness. The result is comprehensive rejuvenation, smoother texture, and improved radiance.
By combining both wavelengths, the Fraxel Dual Restore system enhances precision, minimises recovery time, and ensures optimal outcomes across various treatment areas, making it a gold standard for patients seeking total skin renewal through advanced Fraxel laser treatment technology.
Fraxel 1550 vs 1927: What Each Wavelength Targets
Fraxel is a brand known for pioneering fractionated laser technology that precisely treats microscopic zones of skin while preserving surrounding tissue.
Within the Fraxel Dual treatment system, two laser wavelengths, 1550nm and 1927nm, are employed to target both deep and superficial skin concerns.
Fraxel 1550 for Deep Dermal remodelling
The Fraxel 1550 wavelength penetrates deeply into the dermis, stimulating the body’s remodelling of collagen to repair structural damage beneath the surface. This wavelength excels at improving skin texture, smoothing wrinkles, and fading acne scars by delivering controlled energy that triggers cellular renewal.
During the healing process, collagen fibers reorganise, leading to firmer, smoother, and more healthy skin. The 1550nm setting is also ideal for patients concerned with laser treatment targets aging, such as deep lines and wrinkles, loss of elasticity, and textural irregularities caused by long-term sun exposure.
In medical terms, this wavelength works similarly to an erbium laser but with greater depth control and less surface disruption. Patients undergoing Fraxel repair or deep rejuvenation treatments typically experience longer-lasting tightening and smoother contours as collagen continues to rebuild over several months.
Fraxel 1927 for Superficial Epidermal Pigment
The Fraxel 1927 wavelength is designed to treat surface-level pigment and sun-damaged skin with microscopic laser precision. Operating at a shallower depth, it targets water in the epidermis to lift unwanted pigment, freckles, and melasma while improving skin brightness.
This wavelength is ideal for those looking to refine tone, reduce blotchiness, and achieve a more radiant appearance without significant downtime. It works by creating microscopic thermal zones that trigger exfoliation and renewal while keeping the outer skin barrier largely intact.
For patients who are candidates for Fraxel Dual laser, the 1927nm setting offers a gentle yet effective solution for superficial pigmentation, uneven tone, and mild photodamage. When paired with proper post-care, including daily use of a sunscreen of SPF 30 and avoiding direct sun exposure, the treatment delivers clearer, more luminous skin.
Depth of Penetration and Thermal Profile
Each wavelength in the Fraxel Dual treatment has a unique penetration depth and thermal footprint. The Fraxel 1550 reaches deep into the dermis, generating controlled heat that remodels collagen and tightens underlying structures.
This makes it suitable for improving wrinkles and scars or addressing texture irregularities caused by chronic UV damage.
In contrast, the Fraxel 1927 penetrates the upper skin layers, creating a lighter thermal effect ideal for pigment and tone correction. The result is a comfortable treatment with shorter recovery, perfect for those seeking refreshed, healthy skin without aggressive peeling or extended downtime.
Water vs Collagen Absorption Differences
Absorption characteristics vary between the two treatments, particularly concerning water and collagen. Fraxel 1550 shows higher collagen absorption due to its deeper penetration, facilitating significant skin rejuvenation.
Fraxel 1927, while also beneficial, is primarily focused on water absorption at the surface level. This difference can impact post-treatment hydration and recovery, influencing how skin responds to each wavelength.
- Fraxel 1550: A 1550nm wavelength that penetrates deeply to remodel the dermis, offering high collagen absorption with low water absorption.
- Fraxel 1927: A 1927nm wavelength that targets superficial epidermal pigment, providing shallow penetration with moderate collagen absorption and high water absorption.
Key Differences Between Fraxel 1550 and 1927 (Side-by-Side Breakdown)
The Fraxel Dual laser combines two distinct wavelengths, 1550nm and 1927nm, each designed to target specific skin layers and concerns. These 1550 vs 1927 key differences explain why the device can address a wide range of issues within a single platform.
While both wavelengths belong to the fractionated laser category, they differ significantly in depth, recovery time, and ideal applications.
Targets & Skin Concerns
Fraxel’s two wavelengths work on different layers of the skin, giving each one a distinct role in improving texture, tone, and overall skin quality. The 1550nm targets deeper structural issues, while the 1927nm focuses on surface-level pigmentation and brightness.
Fraxel 1550 (Deep Dermis Targets)
- Treats wrinkles, acne scars, and deeper textural irregularities
- Stimulates collagen remodelling to improve firmness
- Helps correct long-term UV damage and age-related collagen loss
Fraxel 1927 (Epidermal Targets)
- Addresses pigmentation concerns like melasma, freckles, and sun spots
- Smooths and brightens the skin’s surface
- Gently resurfaces the upper layer while keeping the barrier intact
Fraxel Dual (When Both Are Used Together)
- Treats both deep structural issues and surface discoloration
- Enhances overall clarity, radiance, and skin texture
- Provides a more complete rejuvenation outcome
For most patients, combining both wavelengths within a single Fraxel Dual treatment yields optimal results, the 1550nm wavelength rebuilds deeper tissue while the 1927nm wavelength refines tone and clarity on the surface. This dual approach allows for total rejuvenation, restoring both radiance and firmness.
Downtime & Recovery
Downtime varies significantly between the two wavelengths due to their differing depths of action. The Fraxel 1550 penetrates deep into the dermis, triggering a stronger wound-healing response. As a result, patients often experience redness, mild swelling, and a sandpaper-like texture for 3–5 days following treatment. Full recovery may take up to a week, depending on treatment area and intensity.
The Fraxel 1927 wavelength provides a more superficial treatment and therefore a faster recovery period. Most patients experience mild redness and dryness. Light flaking or bronzing may appear as damaged skin cells shed naturally, revealing renewed skin beneath.
Post-treatment care is vital for both wavelengths. Patients are advised to apply gentle moisturisers, avoid direct sun exposure, and use a sunscreen of SPF 30 or higher to protect healing skin. Following these skin care steps reduces the risk of post-inflammatory pigmentation and maintains the results of laser skin resurfacing.
Pain Level & Treatment Intensity
Comfort levels during Fraxel laser treatment depend on the wavelength, energy settings, and individual tolerance. The Fraxel 1550 tends to cause more discomfort because it delivers energy deeper into the dermis, engaging nerve endings more intensely. To manage this, practitioners typically apply topical anaesthetic creams and use cooling air devices throughout the session.
The Fraxel 1927 wavelength is much gentler, producing only mild heat or tingling sensations. Its shallower depth means it affects fewer nerve receptors, making it suitable for patients who prefer minimal discomfort. Most individuals describe the experience as a “warm prickling” rather than pain.
Despite these differences, both treatments are well-tolerated. Patients seeking improvement in fine lines and wrinkles or deeper textural irregularities may find the 1550nm wavelength worthwhile, whereas those targeting pigment or sunspots can achieve visible results with the 1927nm wavelength and minimal recovery disruption.
Safety for Different Skin Types
Safety is a key factor in selecting Fraxel Dual laser treatment. The Fraxel 1550 wavelength works well for most healthy skin types (Fitzpatrick I–IV) but can pose a higher risk of post-inflammatory hyperpigmentation (PIH) in darker tones. A patch test and pre-conditioning are advised for melanin-rich skin.
The Fraxel 1927 wavelength is gentler and safer for sensitive or pigmented skin, targeting the outer epidermis to treat sun damage, uneven tone, and fine lines and wrinkles with minimal downtime. This makes it a preferred choice when evaluating sensitive skin laser suitability.
After treatment, follow strict skin care, avoid direct sun exposure and apply sunscreen of SPF 30 daily. Those with melasma or skin cancer should consult a dermatologist first.
Here’s a quick comparison of both wavelengths:
Fraxel 1550
- Primary target: Deep collagen and texture repair
- Depth of action: Deep dermis
- Best for: Acne scars, wrinkles, rough texture
- Downtime: 3–5 days
- Discomfort: Moderate
- Skin type: Safe for most; caution advised in darker tones
- Aftercare: Hydrate, avoid sun, use SPF 30
Fraxel 1927
- Primary target: Surface pigmentation and tone correction
- Depth of action: Outer epidermis
- Best for: Sunspots, melasma, freckles, dullness
- Downtime: 1–2 days
- Discomfort: Mild
- Skin type: Safe for sensitive or pigmented skin
- Aftercare: Gentle care, moisturise, avoid sun exposure
In essence, Fraxel 1550 offers deeper collagen remodelling, while Fraxel 1927 refines tone and pigment. Together, they deliver a complete rejuvenation system for smoother, radiant skin.
What Is Fraxel 1550 Used For?
Fraxel 1550 is a powerful fractionated laser used for deep laser skin resurfacing, ideal for improving wrinkles and scars, uneven texture, and other long-term skin concerns. By delivering microscopic laser columns into the dermis, it stimulates the body’s remodelling of collagen, helping restore healthy skin from within.
The wavelength’s deeper penetration makes it an excellent choice for rejuvenating damaged tissue and improving elasticity.
Acne Scars & Indented Scarring
One of the most common uses of Fraxel 1550 laser treatment is improving the appearance of acne scars and textural depressions. The laser energy penetrates deeply into the dermis to break down old scar tissue and stimulate new collagen growth.
Over time, this process fills in indented scarring, smooths uneven skin, and enhances overall resilience. Unlike more aggressive procedures, the 1550 laser’s fractionated laser columns treat only microscopic portions of the skin at a time, leaving healthy skin cells intact to speed up recovery.
This targeted approach results in smoother, more balanced skin texture with reduced scarring after several sessions.
Deep Wrinkles & Texture Irregularities
For patients struggling with deep wrinkles, fine lines, and textural roughness, the Fraxel 1550 delivers exceptional results. Its deeper wavelength targets the dermal layer, stimulating fibroblast cells to produce new collagen and elastin. As this natural remodelling occurs, wrinkles gradually soften and the skin regains elasticity.
This laser is particularly beneficial for individuals with long-term sun-damaged skin with microscopic laser changes, where collagen fibers have weakened over time. Compared to surface-focused lasers, the 1550 wavelength repairs damage at its root, leading to lasting improvement in tone and firmness.
When combined with the 1927 setting in a Fraxel Dual treatment, patients achieve a comprehensive rejuvenation, improving deep structure and surface radiance simultaneously.
Stretch Marks & Surgical Scars
Fraxel 1550 is also highly effective in reducing the appearance of stretch marks, surgical scars, and injury-related scars. The laser energy penetrates deep into the dermal matrix, encouraging tissue remodelling and gradual replacement of damaged collagen.
This process strengthens the skin’s support network and smooths the transition between scarred and healthy skin. Over a series of treatments, stretch marks fade in both colour and depth, while surgical scars become flatter and less visible.
Because the treatment promotes natural regeneration, the skin looks healthier and more uniform over time. It’s a preferred method for patients who want meaningful results without the downtime associated with more invasive erbium laser procedures.
When Fraxel 1550 Is Preferred Over 1927
Fraxel 1550 is the treatment of choice for patients whose main goal is to improve skin texture and repair deep structural concerns rather than surface pigmentation. It’s best suited for wrinkles and scars, acne scarring, and areas that require collagen rebuilding, such as the cheeks, temples, and forehead. Those seeking substantial dermal tightening or scar remodelling often respond better to the 1550 wavelength than to the lighter 1927 option.
Following a Fraxel laser treatment, patients should follow strict aftercare: avoid direct sun exposure, use a sunscreen of SPF 30 or higher, and keep the skin well-hydrated. This helps maintain results and prevents skin cancer risks associated with UV exposure during healing.
What Is Fraxel 1927 Used For?
Fraxel 1927 is a fractional laser treatment that targets surface-level skin issues like pigmentation, sun damage, and early ageing. Working in the epidermis, its 1927 nm wavelength removes damaged cells and stimulates renewal for smoother, brighter skin with minimal downtime.
It’s especially effective for freckles, melasma, and actinic keratosis, offering gentle correction for UV-related damage. As part of the Fraxel Dual laser system, it’s ideal for patients seeking clearer, more even-toned skin without extensive recovery.
Sun Damage, Freckles & UV Pigment
Fraxel 1927 laser treatment excels in repairing sun-damaged skin with microscopic laser precision. It gently removes pigmented skin cells and stimulates new, healthy cell turnover in the upper layers. This process effectively fades freckles, sunspots, and uneven pigmentation while promoting smoother texture.
Because UV exposure accelerates the breakdown of collagen and darkens pigment cells, this wavelength is particularly beneficial for individuals with mild photoaging or fine lines and wrinkles caused by long-term sunlight exposure. The laser’s ability to resurface the epidermis helps restore brightness and even tone while preserving the surrounding tissue.
Following each session, strict skin care is crucial, patients must avoid direct sun exposure and use a sunscreen of SPF 30 or higher to prevent pigment recurrence or sensitivity.
Melasma (With Proper Protocols)
Fraxel 1927 can effectively improve melasma when used under proper clinical protocols. Since melasma involves both epidermal and dermal pigment layers, treatment requires cautious settings to avoid triggering inflammation or pigment rebound. The fractionated laser energy breaks apart melanin clusters in the superficial layer, allowing them to fade gradually as the skin regenerates.
Dermatologists often combine Fraxel 1927 with pigment-stabilising serums, antioxidant-rich skin care, and post-laser cooling techniques to maintain safety and control inflammation. When paired with consistent sun protection, patients typically notice a clearer, more balanced tone over multiple sessions.
Unlike older erbium laser systems, which can aggravate melasma by overheating deeper tissue, Fraxel 1927’s precise wavelength confines energy to the epidermis, reducing the risk of relapse while supporting gentle rejuvenation.
Actinic Keratosis (FDA-Approved Indication)
Fraxel 1927 is FDA-approved for treating actinic keratosis (AK), rough, scaly patches caused by chronic UV exposure that can sometimes progress to skin cancer if untreated. The laser vaporises damaged keratinocytes in the epidermis, stimulating new, healthy cell growth beneath the surface.
This treatment offers a safer, less invasive alternative to traditional cryotherapy or chemical peels. Because the fractionated laser targets only damaged areas, it preserves surrounding healthy tissue, resulting in faster healing and fewer side effects. Patients often experience smoother, rejuvenated skin within days, with visible improvement in tone and texture over time.
Regular use of sunscreen of SPF 30 or higher and periodic maintenance sessions can help prevent recurrence, especially for those with fair or UV-sensitive skin types.
When Fraxel 1927 Is Preferred Over 1550
Fraxel 1550 is usually selected when deeper structural change is needed rather than mainly surface level brightening. It tends to be preferred when:
- The main concerns are wrinkles, acne pitting, surgical or traumatic scars and rough or uneven texture
- There is age related collagen loss or long term UV damage affecting firmness and dermal support
- Patients want remodelling of deeper tissue for better elasticity, not just pigment and surface tone improvement
- Textural irregularities and deeper lines are the primary focus and cannot be fully corrected with epidermal resurfacing alone
- Patients are prepared to accept more downtime in exchange for stronger structural improvement and longer lasting results
This way, 1927 reads clearly as the surface and pigment focused option, and 1550 reads clearly as the deeper remodelling option, without changing the clinical meaning of your original section.
Downtime: Fraxel 1550 vs 1927 Recovery Differences
Downtime and recovery are among the most important factors patients consider when comparing Fraxel 1550 and Fraxel 1927 treatments.. The Thulium laser downtime period is generally short, similar to Fraxel 1927, with most patients experiencing only 1–2 days of mild redness or peeling. This helps plan sessions and post-care routines effectively while keeping skin comfortable during recovery.
Immediate Post-Treatment Reactions
After a Fraxel laser treatment, you can expect mild but noticeable reactions immediately following the procedure. Both wavelengths trigger controlled micro-injuries in the skin that stimulate repair, so short-term effects are normal and temporary.
Typical post-treatment responses include:
- Redness and mild swelling in the treatment area (similar to a light sunburn).
- Warmth or tingling that may persist for several hours.
- Temporary sensitivity or tightness, especially in thinner skin regions.
For Fraxel 1550, these sensations may be more pronounced due to the laser’s deeper thermal effect in the dermis. Fraxel 1927, by contrast, produces lighter surface heat and tends to settle faster. Cooling devices, cold compresses, and soothing post-care products recommended by your practitioner can help reduce discomfort.
Avoid direct sun exposure, hot showers, and vigorous exercise for 48 hours post-procedure, and always use a broad-spectrum sunscreen of SPF 30 or higher to protect healing skin.
Healing Timeline for 1550
Because Fraxel 1550 penetrates deeply into the dermis, its recovery time is slightly longer. The laser creates microscopic treatment zones that trigger the body’s remodelling of collagen, improving deep wrinkles and scars over time.
Here’s a typical healing progression for Fraxel 1550:
- Days 1–3: Redness and swelling peak. The treated area may feel warm or tight, and minimal pinpoint bleeding can occur in sensitive zones.
- Days 4–7: Redness gradually fades, and micro-scabs or MENDs (tiny bronzed dots) form as part of the skin’s healing response.
- Weeks 1–2: Scabs naturally exfoliate, revealing smoother, clearer skin beneath. Some residual redness may linger for up to two weeks.
Patients often notice firmer, more even skin within a few weeks as collagen production continues beneath the surface. Makeup can usually be resumed after 5–7 days, provided irritation has resolved.
Healing Timeline for 1927
Fraxel 1927 recovery is generally quicker and more comfortable because it targets only the epidermal layers. It’s ideal for treating sun-damaged skin, freckles, and uneven tone, offering visible brightness and texture improvement with minimal downtime.
Typical healing pattern:
- Days 1–2: Mild redness and swelling, similar to a sunburn. Skin may feel slightly rough or dry.
- Days 3–5: Redness fades quickly. Light peeling or flaking begins as damaged cells shed and healthy skin emerges.
- Weeks 1–2: Skin tone evens out, with enhanced smoothness and glow. Some dryness may persist but can be managed with moisturisers and gentle skin care.
Because of its superficial action, Fraxel 1927 is often chosen by patients who want rapid recovery or need to resume professional or social activities within days.
How Long Redness, MENDs & Peeling Last for Each
After a Fraxel Dual session, redness, dryness and some degree of flaking are normal parts of the healing process. The duration depends on which wavelength was used, because Fraxel 1550 penetrates deeper while Fraxel 1927 focuses on the surface. Here’s how each typically heals:
Fraxel 1550 (Deeper Penetration)
- Redness can last up to 10–14 days, especially with stronger settings
- MENDs (bronzed micro-dots) are common and remain visible for several days
- Peeling or flaking usually continues for 5–7 days as deeper skin begins to remodel
- Recovery feels more “intense” because the wavelength creates deeper thermal impact
Fraxel 1927 (Surface-Level Resurfacing)
- Redness usually fades within 3–5 days, often sooner with proper aftercare
- MENDs are rare, as the wavelength stays within the epidermis
- Light flaking or dryness typically lasts 3–5 days as pigment lifts and the skin brightens
- Overall downtime is milder and more manageable for day-to-day routines
Understanding these timelines helps you plan your treatment schedule and set realistic expectations for visible healing and results.
Results: Fraxel 1550 vs 1927: What to Expect
The results of Fraxel Dual laser treatments depend on both the wavelength used and your skin’s individual response. While both Fraxel 1550 and Fraxel 1927 deliver noticeable rejuvenation, the depth of correction and timeline for visible improvements differ.
The 1550 wavelength focuses on collagen remodelling and deep structural repair, while the 1927 wavelength refines the epidermal layer for smoother texture and even tone.
How Many Sessions Are Needed?
Achieving optimal results typically requires three to five sessions, spaced four to six weeks apart, allowing the skin to heal and generate new collagen between treatments. The exact number varies depending on your goals and skin concerns.
- Fraxel 1550 often requires multiple sessions for deep wrinkles, acne scars, and surgical scars, as collagen renewal occurs progressively.
- Fraxel 1927 may yield faster visible improvement for pigmentation, freckles, or sun-damaged skin, though multiple treatments enhance tone and clarity further.
For maintenance, many patients schedule a touch-up session every 6–12 months to preserve their results and promote consistent collagen activity.
When Results Become Visible
Results from Fraxel 1927 can appear within 1–3 weeks, as surface cells renew and pigment fades. You’ll notice a brighter, smoother complexion and improved tone soon after initial healing.
With Fraxel 1550, results develop more gradually over 2–4 weeks, as deeper collagen remodelling takes effect. Early changes may include softer skin texture and reduced pore visibility, while deeper improvements, such as wrinkle reduction and scar refinement, continue for several months as the dermis regenerates.
Because both treatments rely on the body’s natural healing response, the results compound over time, creating ongoing enhancement rather than an instant transformation.
Longevity of Improvements
Results from Fraxel treatments can last 6–18 months, depending on lifestyle, skincare habits, and natural ageing. The Fraxel 1550 wavelength provides longer-lasting outcomes due to its deep collagen stimulation, while Fraxel 1927 offers faster but slightly shorter-term results for surface renewal.
Longevity is influenced by:
- Sun exposure: consistent use of SPF 30 or higher preserves results.
- Skin care: using antioxidants, retinoids, and moisturisers helps extend the benefits.
- Lifestyle factors: smoking, dehydration, and poor diet can accelerate collagen breakdown.
Patients can maintain results for years with proper aftercare and periodic maintenance sessions, especially when combining both wavelengths as part of a Fraxel Dual laser regimen.
When Patients Usually See Best Results (Time Curve)
Fraxel results develop gradually because the skin continues to remodel and renew in the weeks and months after treatment. Fraxel 1550 works deeper and therefore takes longer to reach full effect, while Fraxel 1927 delivers faster improvements on the skin’s surface. Here’s how the time curve typically looks for each wavelength:
Fraxel 1550 (Deeper remodelling Timeline)
- Most patients need 3–5 sessions for optimal improvement
- Early changes may appear at 2–4 weeks, but full results take longer
- Peak results are usually seen between 2–6 months as collagen rebuilds
- Improvements in wrinkles, scars, and texture can last 6–18 months with good care
Fraxel 1927 (Surface-Level Results Timeline)
- Typically performed in 3–5 sessions, depending on pigmentation severity
- Visible brightening and tone improvement often appear within 1–3 weeks
- Best results continue to develop for 1–3 months as pigment lifts
- Results last around 6–12 months, especially with regular SPF and skincare
Consistent sun protection and a supportive skincare routine help extend your results, and together both wavelengths create smoother, clearer, and naturally rejuvenated skin over time.
Which Fraxel Treatment Is Better for Your Skin Concerns?
Selecting between Fraxel 1550 and Fraxel 1927 depends on your individual skin goals, tone, and tolerance for downtime. Each wavelength has unique advantages, targeting different skin layers and concerns.
While the Fraxel 1927 excels in treating pigmentation and sun damage, the Fraxel 1550 wavelength penetrates deeper to address wrinkles, scars, and texture irregularities.
Choosing Based on Pigmentation vs Texture
The right Fraxel laser treatment depends on whether your focus is tone correction or structural improvement:
- Fraxel 1927 is designed for pigmentation and superficial issues. It effectively treats sunspots, freckles, melasma, and other signs of sun-damaged skin by targeting the epidermis where pigment accumulates. This wavelength works best for those seeking brighter, more even-toned skin with minimal downtime.
- Fraxel 1550, on the other hand, penetrates deeper into the dermis to stimulate collagen production and remodel tissue. It’s ideal for addressing fine lines and wrinkles, acne scars, surgical scars, and rough texture.
By matching your main concern, pigment vs texture, to the right wavelength, you ensure your treatment is precisely aligned with your skin’s biological needs. Those seeking both brightness and firmness often benefit from a customised dual protocol combining both wavelengths.
Combination Treatment (Using 1550 + 1927 Together)
Many patients have overlapping concerns, uneven tone, wrinkles and scars, and loss of radiance. In these cases, the Fraxel Dual laser system combines both 1550 nm and 1927 nm wavelengths in a single session for layered results.
This dual treatment approach rejuvenates the skin on multiple levels:
- The 1927 wavelength renews the outer layer, fading pigment and boosting glow.
- The 1550 wavelength works deeper, strengthening skin structure and improving elasticity.
By addressing both surface irregularities and underlying collagen depletion, this synergy delivers a smoother, firmer, and more even complexion. The combined therapy is especially beneficial for mature skin or those seeking all-around rejuvenation without resorting to fully ablative resurfacing.
A professional evaluation helps determine how to balance both wavelengths for your specific needs, adjusting intensity, number of passes, and treatment intervals for optimal results with minimal downtime.
When to Avoid Each Option
Although both Fraxel systems are safe and non-invasive, certain situations require postponing or avoiding treatment altogether:
- Active skin infections, open wounds, or active acne breakouts can increase irritation and risk of complications.
- Recent tanning or direct sun exposure makes skin more photosensitive and prone to pigment changes.
- Pregnancy, severe eczema, rosacea flare-ups, or autoimmune conditions may contraindicate treatment.
- Those with a history of keloid formation or poor wound healing should discuss these concerns with their dermatologist before proceeding.
In such cases, a delay or modified treatment plan ensures that your skin remains safe and healthy. Your provider may recommend pre-conditioning protocols, such as topical brighteners, antioxidants, or gentle exfoliation, to prepare the skin before laser sessions.
When Fitzpatrick Skin Scale Impacts Selection
The Fitzpatrick skin scale helps determine how different skin types respond to laser energy. It ranges from Type I (very fair) to Type VI (deeply pigmented) and is crucial in guiding wavelength choice and intensity settings:
- Types I–III (lighter tones) generally tolerate both Fraxel 1550 and 1927 safely, achieving excellent results with minimal pigment risk.
- Types IV–VI (medium to dark tones) require extra caution. While Fraxel 1550 can often be used with adjusted energy levels, Fraxel 1927 should be approached conservatively due to its higher interaction with epidermal melanin.
For melanin-rich skin, practitioners typically perform a patch test and use pre-treatment brightening agents to stabilise pigment. Post-procedure, strict sun avoidance and the daily use of sunscreen of SPF 30 or higher are essential to prevent post-inflammatory hyperpigmentation (PIH).
By tailoring laser settings based on your Fitzpatrick type, practitioners can achieve visible improvements while preserving tone balance and minimising risk.
Fraxel 1550 vs 1927: Cost Differences & Treatment Value
When comparing Fraxel 1550 vs 1927, cost differences mainly reflect the treatment depth, energy levels used, and practitioner expertise. Fraxel 1550 sessions generally cost more because they require deeper dermal penetration, more precision, and longer recovery guidance. Fraxel 1927 is typically priced slightly lower, as it focuses on surface pigmentation and tone.

- Clinic location: Urban centres (London, NYC, LA, Sydney) charge more due to higher demand and premium devices.
Note: Individual responses and treatment plans will determine exact costs.
When Fitzpatrick Skin Scale Impacts Cost and Selection
Your skin tone can influence which wavelength you receive,and therefore affect treatment pricing.
- Fitzpatrick I–III (light to medium skin tones): Eligible for both Fraxel 1550 and 1927; often benefit from dual-wavelength sessions (which cost more).
- Fitzpatrick IV–VI (medium-deep to dark skin tones): Usually better suited to Fraxel 1927 to reduce the risk of post-inflammatory hyperpigmentation (PIH). Providers may perform patch testing or require pre-treatment brightening, which adds minor cost.
Note: Safety protocols for darker skin may increase the total treatment plan cost.

Understanding Fraxel Dual: The 1550nm vs 1927nm Wavelengths
Fractional laser technology represents a significant advancement in the field of skin rejuvenation and treatment. This approach allows precise targeting of skin imperfections while maintaining the integrity of surrounding healthy tissue.
The technology includes both ablative and non-ablative systems, with non-ablative options such as the Thulium 1927nm laser and Fraxel Dual offering a safer method for controlled skin resurfacing with minimal downtime.
How Fractional Laser Technology Works
Fractional laser technology is built on the principle of treating only a fraction of the skin at a time, creating controlled microthermal zones while leaving surrounding tissue intact. During a Fraxel laser treatment, the device emits a grid of microscopic beams that penetrate the surface, reaching precise depths within the skin cells.
These micro-injuries stimulate collagen and elastin production, essential for repairing fine lines and wrinkles and improving overall texture. By targeting specific treatment areas while preserving nearby skin, fractional delivery accelerates the body’s natural healing process.
This controlled regeneration reduces downtime compared to fully ablative lasers and provides long-term improvement for wrinkles and scars, sun damage, and uneven pigmentation.
The Science Behind Non-Ablative Laser Resurfacing
Non-ablative lasers, such as those used in the Fraxel Dual laser and Fraxel Dual Restore systems, work beneath the skin’s surface without removing the epidermis. Instead, they deliver heat energy to the dermal layer, encouraging collagen remodelling and promoting the growth of new, healthy skin cells.
This approach is highly effective for smoothing lines and wrinkles while maintaining the integrity of the skin barrier. Because non-ablative treatments don’t break the surface, patients experience faster recovery and minimal risk of infection.
With proper skin care after treatment, including hydration and daily protection using SPF 30 or higher, you can safely return to regular routines within days. Avoiding direct sun exposure post-treatment helps preserve results and reduces the risk of pigmentation changes or long-term damage such as skin cancer.
Why Fraxel Uses Two Wavelengths Instead of One (The Dual Concept)
The Fraxel Dual laser operates using two distinct wavelengths, 1550nm and 1927nm, each targeting different skin layers and concerns. The 1550nm wavelength penetrates deeper into the dermis to stimulate collagen growth and repair structural damage from wrinkles and scars, while the 1927nm wavelength focuses on the epidermis to improve tone, texture, and superficial pigmentation.
This dual treatment concept allows dermatologists to address multiple issues in one session, from deep fine lines and wrinkles to surface-level sunspots or roughness. The result is comprehensive rejuvenation, smoother texture, and improved radiance.
By combining both wavelengths, the Fraxel Dual Restore system enhances precision, minimises recovery time, and ensures optimal outcomes across various treatment areas, making it a gold standard for patients seeking total skin renewal through advanced Fraxel laser treatment technology.
Fraxel 1550 vs 1927: What Each Wavelength Targets
Fraxel is a brand known for pioneering fractionated laser technology that precisely treats microscopic zones of skin while preserving surrounding tissue.
Within the Fraxel Dual treatment system, two laser wavelengths, 1550nm and 1927nm, are employed to target both deep and superficial skin concerns.
Fraxel 1550 for Deep Dermal remodelling
The Fraxel 1550 wavelength penetrates deeply into the dermis, stimulating the body’s remodelling of collagen to repair structural damage beneath the surface. This wavelength excels at improving skin texture, smoothing wrinkles, and fading acne scars by delivering controlled energy that triggers cellular renewal.
During the healing process, collagen fibers reorganise, leading to firmer, smoother, and more healthy skin. The 1550nm setting is also ideal for patients concerned with laser treatment targets aging, such as deep lines and wrinkles, loss of elasticity, and textural irregularities caused by long-term sun exposure.
In medical terms, this wavelength works similarly to an erbium laser but with greater depth control and less surface disruption. Patients undergoing Fraxel repair or deep rejuvenation treatments typically experience longer-lasting tightening and smoother contours as collagen continues to rebuild over several months.
Fraxel 1927 for Superficial Epidermal Pigment
The Fraxel 1927 wavelength is designed to treat surface-level pigment and sun-damaged skin with microscopic laser precision. Operating at a shallower depth, it targets water in the epidermis to lift unwanted pigment, freckles, and melasma while improving skin brightness.
This wavelength is ideal for those looking to refine tone, reduce blotchiness, and achieve a more radiant appearance without significant downtime. It works by creating microscopic thermal zones that trigger exfoliation and renewal while keeping the outer skin barrier largely intact.
For patients who are candidates for Fraxel Dual laser, the 1927nm setting offers a gentle yet effective solution for superficial pigmentation, uneven tone, and mild photodamage. When paired with proper post-care, including daily use of a sunscreen of SPF 30 and avoiding direct sun exposure, the treatment delivers clearer, more luminous skin.
Depth of Penetration and Thermal Profile
Each wavelength in the Fraxel Dual treatment has a unique penetration depth and thermal footprint. The Fraxel 1550 reaches deep into the dermis, generating controlled heat that remodels collagen and tightens underlying structures.
This makes it suitable for improving wrinkles and scars or addressing texture irregularities caused by chronic UV damage.
In contrast, the Fraxel 1927 penetrates the upper skin layers, creating a lighter thermal effect ideal for pigment and tone correction. The result is a comfortable treatment with shorter recovery, perfect for those seeking refreshed, healthy skin without aggressive peeling or extended downtime.
Water vs Collagen Absorption Differences
Absorption characteristics vary between the two treatments, particularly concerning water and collagen. Fraxel 1550 shows higher collagen absorption due to its deeper penetration, facilitating significant skin rejuvenation.
Fraxel 1927, while also beneficial, is primarily focused on water absorption at the surface level. This difference can impact post-treatment hydration and recovery, influencing how skin responds to each wavelength.
- Fraxel 1550: A 1550nm wavelength that penetrates deeply to remodel the dermis, offering high collagen absorption with low water absorption.
- Fraxel 1927: A 1927nm wavelength that targets superficial epidermal pigment, providing shallow penetration with moderate collagen absorption and high water absorption.
Key Differences Between Fraxel 1550 and 1927 (Side-by-Side Breakdown)
The Fraxel Dual laser combines two distinct wavelengths, 1550nm and 1927nm, each designed to target specific skin layers and concerns. These 1550 vs 1927 key differences explain why the device can address a wide range of issues within a single platform.
While both wavelengths belong to the fractionated laser category, they differ significantly in depth, recovery time, and ideal applications.
Targets & Skin Concerns
Fraxel’s two wavelengths work on different layers of the skin, giving each one a distinct role in improving texture, tone, and overall skin quality. The 1550nm targets deeper structural issues, while the 1927nm focuses on surface-level pigmentation and brightness.
Fraxel 1550 (Deep Dermis Targets)
- Treats wrinkles, acne scars, and deeper textural irregularities
- Stimulates collagen remodelling to improve firmness
- Helps correct long-term UV damage and age-related collagen loss
Fraxel 1927 (Epidermal Targets)
- Addresses pigmentation concerns like melasma, freckles, and sun spots
- Smooths and brightens the skin’s surface
- Gently resurfaces the upper layer while keeping the barrier intact
Fraxel Dual (When Both Are Used Together)
- Treats both deep structural issues and surface discoloration
- Enhances overall clarity, radiance, and skin texture
- Provides a more complete rejuvenation outcome
For most patients, combining both wavelengths within a single Fraxel Dual treatment yields optimal results, the 1550nm wavelength rebuilds deeper tissue while the 1927nm wavelength refines tone and clarity on the surface. This dual approach allows for total rejuvenation, restoring both radiance and firmness.
Downtime & Recovery
Downtime varies significantly between the two wavelengths due to their differing depths of action. The Fraxel 1550 penetrates deep into the dermis, triggering a stronger wound-healing response. As a result, patients often experience redness, mild swelling, and a sandpaper-like texture for 3–5 days following treatment. Full recovery may take up to a week, depending on treatment area and intensity.
The Fraxel 1927 wavelength provides a more superficial treatment and therefore a faster recovery period. Most patients experience mild redness and dryness. Light flaking or bronzing may appear as damaged skin cells shed naturally, revealing renewed skin beneath.
Post-treatment care is vital for both wavelengths. Patients are advised to apply gentle moisturisers, avoid direct sun exposure, and use a sunscreen of SPF 30 or higher to protect healing skin. Following these skin care steps reduces the risk of post-inflammatory pigmentation and maintains the results of laser skin resurfacing.
Pain Level & Treatment Intensity
Comfort levels during Fraxel laser treatment depend on the wavelength, energy settings, and individual tolerance. The Fraxel 1550 tends to cause more discomfort because it delivers energy deeper into the dermis, engaging nerve endings more intensely. To manage this, practitioners typically apply topical anaesthetic creams and use cooling air devices throughout the session.
The Fraxel 1927 wavelength is much gentler, producing only mild heat or tingling sensations. Its shallower depth means it affects fewer nerve receptors, making it suitable for patients who prefer minimal discomfort. Most individuals describe the experience as a “warm prickling” rather than pain.
Despite these differences, both treatments are well-tolerated. Patients seeking improvement in fine lines and wrinkles or deeper textural irregularities may find the 1550nm wavelength worthwhile, whereas those targeting pigment or sunspots can achieve visible results with the 1927nm wavelength and minimal recovery disruption.
Safety for Different Skin Types
Safety is a key factor in selecting Fraxel Dual laser treatment. The Fraxel 1550 wavelength works well for most healthy skin types (Fitzpatrick I–IV) but can pose a higher risk of post-inflammatory hyperpigmentation (PIH) in darker tones. A patch test and pre-conditioning are advised for melanin-rich skin.
The Fraxel 1927 wavelength is gentler and safer for sensitive or pigmented skin, targeting the outer epidermis to treat sun damage, uneven tone, and fine lines and wrinkles with minimal downtime. This makes it a preferred choice when evaluating sensitive skin laser suitability.
After treatment, follow strict skin care, avoid direct sun exposure and apply sunscreen of SPF 30 daily. Those with melasma or skin cancer should consult a dermatologist first.
Here’s a quick comparison of both wavelengths:
Fraxel 1550
- Primary target: Deep collagen and texture repair
- Depth of action: Deep dermis
- Best for: Acne scars, wrinkles, rough texture
- Downtime: 3–5 days
- Discomfort: Moderate
- Skin type: Safe for most; caution advised in darker tones
- Aftercare: Hydrate, avoid sun, use SPF 30
Fraxel 1927
- Primary target: Surface pigmentation and tone correction
- Depth of action: Outer epidermis
- Best for: Sunspots, melasma, freckles, dullness
- Downtime: 1–2 days
- Discomfort: Mild
- Skin type: Safe for sensitive or pigmented skin
- Aftercare: Gentle care, moisturise, avoid sun exposure
In essence, Fraxel 1550 offers deeper collagen remodelling, while Fraxel 1927 refines tone and pigment. Together, they deliver a complete rejuvenation system for smoother, radiant skin.
What Is Fraxel 1550 Used For?
Fraxel 1550 is a powerful fractionated laser used for deep laser skin resurfacing, ideal for improving wrinkles and scars, uneven texture, and other long-term skin concerns. By delivering microscopic laser columns into the dermis, it stimulates the body’s remodelling of collagen, helping restore healthy skin from within.
The wavelength’s deeper penetration makes it an excellent choice for rejuvenating damaged tissue and improving elasticity.
Acne Scars & Indented Scarring
One of the most common uses of Fraxel 1550 laser treatment is improving the appearance of acne scars and textural depressions. The laser energy penetrates deeply into the dermis to break down old scar tissue and stimulate new collagen growth.
Over time, this process fills in indented scarring, smooths uneven skin, and enhances overall resilience. Unlike more aggressive procedures, the 1550 laser’s fractionated laser columns treat only microscopic portions of the skin at a time, leaving healthy skin cells intact to speed up recovery.
This targeted approach results in smoother, more balanced skin texture with reduced scarring after several sessions.
Deep Wrinkles & Texture Irregularities
For patients struggling with deep wrinkles, fine lines, and textural roughness, the Fraxel 1550 delivers exceptional results. Its deeper wavelength targets the dermal layer, stimulating fibroblast cells to produce new collagen and elastin. As this natural remodelling occurs, wrinkles gradually soften and the skin regains elasticity.
This laser is particularly beneficial for individuals with long-term sun-damaged skin with microscopic laser changes, where collagen fibers have weakened over time. Compared to surface-focused lasers, the 1550 wavelength repairs damage at its root, leading to lasting improvement in tone and firmness.
When combined with the 1927 setting in a Fraxel Dual treatment, patients achieve a comprehensive rejuvenation, improving deep structure and surface radiance simultaneously.
Stretch Marks & Surgical Scars
Fraxel 1550 is also highly effective in reducing the appearance of stretch marks, surgical scars, and injury-related scars. The laser energy penetrates deep into the dermal matrix, encouraging tissue remodelling and gradual replacement of damaged collagen.
This process strengthens the skin’s support network and smooths the transition between scarred and healthy skin. Over a series of treatments, stretch marks fade in both colour and depth, while surgical scars become flatter and less visible.
Because the treatment promotes natural regeneration, the skin looks healthier and more uniform over time. It’s a preferred method for patients who want meaningful results without the downtime associated with more invasive erbium laser procedures.
When Fraxel 1550 Is Preferred Over 1927
Fraxel 1550 is the treatment of choice for patients whose main goal is to improve skin texture and repair deep structural concerns rather than surface pigmentation. It’s best suited for wrinkles and scars, acne scarring, and areas that require collagen rebuilding, such as the cheeks, temples, and forehead. Those seeking substantial dermal tightening or scar remodelling often respond better to the 1550 wavelength than to the lighter 1927 option.
Following a Fraxel laser treatment, patients should follow strict aftercare: avoid direct sun exposure, use a sunscreen of SPF 30 or higher, and keep the skin well-hydrated. This helps maintain results and prevents skin cancer risks associated with UV exposure during healing.
What Is Fraxel 1927 Used For?
Fraxel 1927 is a fractional laser treatment that targets surface-level skin issues like pigmentation, sun damage, and early ageing. Working in the epidermis, its 1927 nm wavelength removes damaged cells and stimulates renewal for smoother, brighter skin with minimal downtime.
It’s especially effective for freckles, melasma, and actinic keratosis, offering gentle correction for UV-related damage. As part of the Fraxel Dual laser system, it’s ideal for patients seeking clearer, more even-toned skin without extensive recovery.
Sun Damage, Freckles & UV Pigment
Fraxel 1927 laser treatment excels in repairing sun-damaged skin with microscopic laser precision. It gently removes pigmented skin cells and stimulates new, healthy cell turnover in the upper layers. This process effectively fades freckles, sunspots, and uneven pigmentation while promoting smoother texture.
Because UV exposure accelerates the breakdown of collagen and darkens pigment cells, this wavelength is particularly beneficial for individuals with mild photoaging or fine lines and wrinkles caused by long-term sunlight exposure. The laser’s ability to resurface the epidermis helps restore brightness and even tone while preserving the surrounding tissue.
Following each session, strict skin care is crucial, patients must avoid direct sun exposure and use a sunscreen of SPF 30 or higher to prevent pigment recurrence or sensitivity.
Melasma (With Proper Protocols)
Fraxel 1927 can effectively improve melasma when used under proper clinical protocols. Since melasma involves both epidermal and dermal pigment layers, treatment requires cautious settings to avoid triggering inflammation or pigment rebound. The fractionated laser energy breaks apart melanin clusters in the superficial layer, allowing them to fade gradually as the skin regenerates.
Dermatologists often combine Fraxel 1927 with pigment-stabilising serums, antioxidant-rich skin care, and post-laser cooling techniques to maintain safety and control inflammation. When paired with consistent sun protection, patients typically notice a clearer, more balanced tone over multiple sessions.
Unlike older erbium laser systems, which can aggravate melasma by overheating deeper tissue, Fraxel 1927’s precise wavelength confines energy to the epidermis, reducing the risk of relapse while supporting gentle rejuvenation.
Actinic Keratosis (FDA-Approved Indication)
Fraxel 1927 is FDA-approved for treating actinic keratosis (AK), rough, scaly patches caused by chronic UV exposure that can sometimes progress to skin cancer if untreated. The laser vaporises damaged keratinocytes in the epidermis, stimulating new, healthy cell growth beneath the surface.
This treatment offers a safer, less invasive alternative to traditional cryotherapy or chemical peels. Because the fractionated laser targets only damaged areas, it preserves surrounding healthy tissue, resulting in faster healing and fewer side effects. Patients often experience smoother, rejuvenated skin within days, with visible improvement in tone and texture over time.
Regular use of sunscreen of SPF 30 or higher and periodic maintenance sessions can help prevent recurrence, especially for those with fair or UV-sensitive skin types.
When Fraxel 1927 Is Preferred Over 1550
Fraxel 1550 is usually selected when deeper structural change is needed rather than mainly surface level brightening. It tends to be preferred when:
- The main concerns are wrinkles, acne pitting, surgical or traumatic scars and rough or uneven texture
- There is age related collagen loss or long term UV damage affecting firmness and dermal support
- Patients want remodelling of deeper tissue for better elasticity, not just pigment and surface tone improvement
- Textural irregularities and deeper lines are the primary focus and cannot be fully corrected with epidermal resurfacing alone
- Patients are prepared to accept more downtime in exchange for stronger structural improvement and longer lasting results
This way, 1927 reads clearly as the surface and pigment focused option, and 1550 reads clearly as the deeper remodelling option, without changing the clinical meaning of your original section.
Downtime: Fraxel 1550 vs 1927 Recovery Differences
Downtime and recovery are among the most important factors patients consider when comparing Fraxel 1550 and Fraxel 1927 treatments.. The Thulium laser downtime period is generally short, similar to Fraxel 1927, with most patients experiencing only 1–2 days of mild redness or peeling. This helps plan sessions and post-care routines effectively while keeping skin comfortable during recovery.
Immediate Post-Treatment Reactions
After a Fraxel laser treatment, you can expect mild but noticeable reactions immediately following the procedure. Both wavelengths trigger controlled micro-injuries in the skin that stimulate repair, so short-term effects are normal and temporary.
Typical post-treatment responses include:
- Redness and mild swelling in the treatment area (similar to a light sunburn).
- Warmth or tingling that may persist for several hours.
- Temporary sensitivity or tightness, especially in thinner skin regions.
For Fraxel 1550, these sensations may be more pronounced due to the laser’s deeper thermal effect in the dermis. Fraxel 1927, by contrast, produces lighter surface heat and tends to settle faster. Cooling devices, cold compresses, and soothing post-care products recommended by your practitioner can help reduce discomfort.
Avoid direct sun exposure, hot showers, and vigorous exercise for 48 hours post-procedure, and always use a broad-spectrum sunscreen of SPF 30 or higher to protect healing skin.
Healing Timeline for 1550
Because Fraxel 1550 penetrates deeply into the dermis, its recovery time is slightly longer. The laser creates microscopic treatment zones that trigger the body’s remodelling of collagen, improving deep wrinkles and scars over time.
Here’s a typical healing progression for Fraxel 1550:
- Days 1–3: Redness and swelling peak. The treated area may feel warm or tight, and minimal pinpoint bleeding can occur in sensitive zones.
- Days 4–7: Redness gradually fades, and micro-scabs or MENDs (tiny bronzed dots) form as part of the skin’s healing response.
- Weeks 1–2: Scabs naturally exfoliate, revealing smoother, clearer skin beneath. Some residual redness may linger for up to two weeks.
Patients often notice firmer, more even skin within a few weeks as collagen production continues beneath the surface. Makeup can usually be resumed after 5–7 days, provided irritation has resolved.
Healing Timeline for 1927
Fraxel 1927 recovery is generally quicker and more comfortable because it targets only the epidermal layers. It’s ideal for treating sun-damaged skin, freckles, and uneven tone, offering visible brightness and texture improvement with minimal downtime.
Typical healing pattern:
- Days 1–2: Mild redness and swelling, similar to a sunburn. Skin may feel slightly rough or dry.
- Days 3–5: Redness fades quickly. Light peeling or flaking begins as damaged cells shed and healthy skin emerges.
- Weeks 1–2: Skin tone evens out, with enhanced smoothness and glow. Some dryness may persist but can be managed with moisturisers and gentle skin care.
Because of its superficial action, Fraxel 1927 is often chosen by patients who want rapid recovery or need to resume professional or social activities within days.
How Long Redness, MENDs & Peeling Last for Each
After a Fraxel Dual session, redness, dryness and some degree of flaking are normal parts of the healing process. The duration depends on which wavelength was used, because Fraxel 1550 penetrates deeper while Fraxel 1927 focuses on the surface. Here’s how each typically heals:
Fraxel 1550 (Deeper Penetration)
- Redness can last up to 10–14 days, especially with stronger settings
- MENDs (bronzed micro-dots) are common and remain visible for several days
- Peeling or flaking usually continues for 5–7 days as deeper skin begins to remodel
- Recovery feels more “intense” because the wavelength creates deeper thermal impact
Fraxel 1927 (Surface-Level Resurfacing)
- Redness usually fades within 3–5 days, often sooner with proper aftercare
- MENDs are rare, as the wavelength stays within the epidermis
- Light flaking or dryness typically lasts 3–5 days as pigment lifts and the skin brightens
- Overall downtime is milder and more manageable for day-to-day routines
Understanding these timelines helps you plan your treatment schedule and set realistic expectations for visible healing and results.
Results: Fraxel 1550 vs 1927: What to Expect
The results of Fraxel Dual laser treatments depend on both the wavelength used and your skin’s individual response. While both Fraxel 1550 and Fraxel 1927 deliver noticeable rejuvenation, the depth of correction and timeline for visible improvements differ.
The 1550 wavelength focuses on collagen remodelling and deep structural repair, while the 1927 wavelength refines the epidermal layer for smoother texture and even tone.
How Many Sessions Are Needed?
Achieving optimal results typically requires three to five sessions, spaced four to six weeks apart, allowing the skin to heal and generate new collagen between treatments. The exact number varies depending on your goals and skin concerns.
- Fraxel 1550 often requires multiple sessions for deep wrinkles, acne scars, and surgical scars, as collagen renewal occurs progressively.
- Fraxel 1927 may yield faster visible improvement for pigmentation, freckles, or sun-damaged skin, though multiple treatments enhance tone and clarity further.
For maintenance, many patients schedule a touch-up session every 6–12 months to preserve their results and promote consistent collagen activity.
When Results Become Visible
Results from Fraxel 1927 can appear within 1–3 weeks, as surface cells renew and pigment fades. You’ll notice a brighter, smoother complexion and improved tone soon after initial healing.
With Fraxel 1550, results develop more gradually over 2–4 weeks, as deeper collagen remodelling takes effect. Early changes may include softer skin texture and reduced pore visibility, while deeper improvements, such as wrinkle reduction and scar refinement, continue for several months as the dermis regenerates.
Because both treatments rely on the body’s natural healing response, the results compound over time, creating ongoing enhancement rather than an instant transformation.
Longevity of Improvements
Results from Fraxel treatments can last 6–18 months, depending on lifestyle, skincare habits, and natural ageing. The Fraxel 1550 wavelength provides longer-lasting outcomes due to its deep collagen stimulation, while Fraxel 1927 offers faster but slightly shorter-term results for surface renewal.
Longevity is influenced by:
- Sun exposure: consistent use of SPF 30 or higher preserves results.
- Skin care: using antioxidants, retinoids, and moisturisers helps extend the benefits.
- Lifestyle factors: smoking, dehydration, and poor diet can accelerate collagen breakdown.
Patients can maintain results for years with proper aftercare and periodic maintenance sessions, especially when combining both wavelengths as part of a Fraxel Dual laser regimen.
When Patients Usually See Best Results (Time Curve)
Fraxel results develop gradually because the skin continues to remodel and renew in the weeks and months after treatment. Fraxel 1550 works deeper and therefore takes longer to reach full effect, while Fraxel 1927 delivers faster improvements on the skin’s surface. Here’s how the time curve typically looks for each wavelength:
Fraxel 1550 (Deeper remodelling Timeline)
- Most patients need 3–5 sessions for optimal improvement
- Early changes may appear at 2–4 weeks, but full results take longer
- Peak results are usually seen between 2–6 months as collagen rebuilds
- Improvements in wrinkles, scars, and texture can last 6–18 months with good care
Fraxel 1927 (Surface-Level Results Timeline)
- Typically performed in 3–5 sessions, depending on pigmentation severity
- Visible brightening and tone improvement often appear within 1–3 weeks
- Best results continue to develop for 1–3 months as pigment lifts
- Results last around 6–12 months, especially with regular SPF and skincare
Consistent sun protection and a supportive skincare routine help extend your results, and together both wavelengths create smoother, clearer, and naturally rejuvenated skin over time.
Which Fraxel Treatment Is Better for Your Skin Concerns?
Selecting between Fraxel 1550 and Fraxel 1927 depends on your individual skin goals, tone, and tolerance for downtime. Each wavelength has unique advantages, targeting different skin layers and concerns.
While the Fraxel 1927 excels in treating pigmentation and sun damage, the Fraxel 1550 wavelength penetrates deeper to address wrinkles, scars, and texture irregularities.
Choosing Based on Pigmentation vs Texture
The right Fraxel laser treatment depends on whether your focus is tone correction or structural improvement:
- Fraxel 1927 is designed for pigmentation and superficial issues. It effectively treats sunspots, freckles, melasma, and other signs of sun-damaged skin by targeting the epidermis where pigment accumulates. This wavelength works best for those seeking brighter, more even-toned skin with minimal downtime.
- Fraxel 1550, on the other hand, penetrates deeper into the dermis to stimulate collagen production and remodel tissue. It’s ideal for addressing fine lines and wrinkles, acne scars, surgical scars, and rough texture.
By matching your main concern, pigment vs texture, to the right wavelength, you ensure your treatment is precisely aligned with your skin’s biological needs. Those seeking both brightness and firmness often benefit from a customised dual protocol combining both wavelengths.
Combination Treatment (Using 1550 + 1927 Together)
Many patients have overlapping concerns, uneven tone, wrinkles and scars, and loss of radiance. In these cases, the Fraxel Dual laser system combines both 1550 nm and 1927 nm wavelengths in a single session for layered results.
This dual treatment approach rejuvenates the skin on multiple levels:
- The 1927 wavelength renews the outer layer, fading pigment and boosting glow.
- The 1550 wavelength works deeper, strengthening skin structure and improving elasticity.
By addressing both surface irregularities and underlying collagen depletion, this synergy delivers a smoother, firmer, and more even complexion. The combined therapy is especially beneficial for mature skin or those seeking all-around rejuvenation without resorting to fully ablative resurfacing.
A professional evaluation helps determine how to balance both wavelengths for your specific needs, adjusting intensity, number of passes, and treatment intervals for optimal results with minimal downtime.
When to Avoid Each Option
Although both Fraxel systems are safe and non-invasive, certain situations require postponing or avoiding treatment altogether:
- Active skin infections, open wounds, or active acne breakouts can increase irritation and risk of complications.
- Recent tanning or direct sun exposure makes skin more photosensitive and prone to pigment changes.
- Pregnancy, severe eczema, rosacea flare-ups, or autoimmune conditions may contraindicate treatment.
- Those with a history of keloid formation or poor wound healing should discuss these concerns with their dermatologist before proceeding.
In such cases, a delay or modified treatment plan ensures that your skin remains safe and healthy. Your provider may recommend pre-conditioning protocols, such as topical brighteners, antioxidants, or gentle exfoliation, to prepare the skin before laser sessions.
When Fitzpatrick Skin Scale Impacts Selection
The Fitzpatrick skin scale helps determine how different skin types respond to laser energy. It ranges from Type I (very fair) to Type VI (deeply pigmented) and is crucial in guiding wavelength choice and intensity settings:
- Types I–III (lighter tones) generally tolerate both Fraxel 1550 and 1927 safely, achieving excellent results with minimal pigment risk.
- Types IV–VI (medium to dark tones) require extra caution. While Fraxel 1550 can often be used with adjusted energy levels, Fraxel 1927 should be approached conservatively due to its higher interaction with epidermal melanin.
For melanin-rich skin, practitioners typically perform a patch test and use pre-treatment brightening agents to stabilise pigment. Post-procedure, strict sun avoidance and the daily use of sunscreen of SPF 30 or higher are essential to prevent post-inflammatory hyperpigmentation (PIH).
By tailoring laser settings based on your Fitzpatrick type, practitioners can achieve visible improvements while preserving tone balance and minimising risk.
Fraxel 1550 vs 1927: Cost Differences & Treatment Value
When comparing Fraxel 1550 vs 1927, cost differences mainly reflect the treatment depth, energy levels used, and practitioner expertise. Fraxel 1550 sessions generally cost more because they require deeper dermal penetration, more precision, and longer recovery guidance. Fraxel 1927 is typically priced slightly lower, as it focuses on surface pigmentation and tone.
Average Cost Per Session
Across major clinics in the UK, Fraxel treatments usually fall within a $700–$1,200 (£550–£950) per-session range. Smaller areas such as the cheeks, temples, or under-eye region are priced on the lower end, while full-face or combined 1550 + 1927 sessions sit on the higher end.
Tentative Cost Ranges
Fraxel 1550 (dermal resurfacing): $900–$1,350 (£700–£1,100) per session. Higher pricing reflects deeper tissue targeting, increased discomfort management, and the precision required for dermal-level resurfacing.
Fraxel 1927 (epidermal resurfacing): $700–$1,000 (£550–£850) per session. Lower costs are associated with its superficial nature, shorter downtimes, and reduced need for post-treatment management.
Treatment Frequency: Most patients need 3–5 sessions, spaced 4–6 weeks apart, for full results.
Note: These figures are indicative estimates. Actual pricing will vary by clinic, city, practitioner expertise, treatment duration, device model, and the level of correction required.
Why Pricing Differs
The pricing gap between Fraxel 1550 and 1927 comes from treatment intensity and depth:
- Fraxel 1550: Works in the deeper dermis, stimulating collagen remodelling; requires higher energy settings, more clinical oversight, and longer post-care support.
- Fraxel 1927: Focuses on exfoliating superficial pigment, removing sunspots, and brightening the complexion with less procedural intensity.
Additional reasons for cost variability include:
- Technology & consumables: Fractional laser tips and cooling systems raise operating costs.
- Practitioner skill: Board-certified dermatologists charge more due to training and safety standards.
- Clinic environment: High-end or metropolitan clinics often include follow-ups, LED therapy, or medical-grade skincare.
Note: Device generation (e.g., original Fraxel vs Fraxel Dual) may also influence pricing.
Factors That Influence the Total Treatment Cost
Your final investment depends on several variables:
- Treatment area size: Full face > neck > spot treatment.
- Number of sessions: Fraxel 1550 usually requires more sessions than 1927.
- Skin condition severity: Deep scars, etched wrinkles, and long-term sun damage need stronger settings.
- Maintenance products: Gentle cleansers, barrier creams, and SPF increase total cost but protect results.
- Clinic location: Urban centres (London, NYC, LA, Sydney) charge more due to higher demand and premium devices.
Note: Individual responses and treatment plans will determine exact costs.
When Fitzpatrick Skin Scale Impacts Cost and Selection
Your skin tone can influence which wavelength you receive,and therefore affect treatment pricing.
- Fitzpatrick I–III (light to medium skin tones): Eligible for both Fraxel 1550 and 1927; often benefit from dual-wavelength sessions (which cost more).
- Fitzpatrick IV–VI (medium-deep to dark skin tones): Usually better suited to Fraxel 1927 to reduce the risk of post-inflammatory hyperpigmentation (PIH). Providers may perform patch testing or require pre-treatment brightening, which adds minor cost.
Note: Safety protocols for darker skin may increase the total treatment plan cost.
Before You Go
Whether you’re considering Fraxel Dual or just Thulium laser treatment, it’s important to consult a qualified practitioner who understands both laser physics and skin biology.
Choosing the right wavelength, whether Fraxel 1550 for deep remodelling or Fraxel 1927 for surface pigment, depends on your skin type, goals, and medical history.
Always prioritise clinics that follow strict safety standards, use evidence-based protocols, and offer structured aftercare; the same principles we follow at the Institute of Medical Physics to ensure safer, long-lasting results.
