What Is a Nasolabial Fold Filler?
Nasolabial foldsâcommonly known as smile lines or laugh linesâare the visible creases that extend from the nose to the corners of the mouth. Over time, these lines deepen due to collagen and elastin loss, repetitive facial movements, and natural volume loss.
â
A nasolabial fold filler is a dermal filler injection designed to add volume and soften these folds, restoring a youthful appearance. At the Institute of Medical Physics in London, we use premium hyaluronic acid-based fillers to smooth away these lines safely, effectively, and naturally.
â
Whether youâre looking to prevent early signs of aging or reduce already prominent folds, our non-surgical filler treatment offers a customised approach to revitalise your appearance without altering your expressions.
What Can Nasolabial Filler Treat?
Our expert injectable solutions target multiple concerns related to facial aging. A nasolabial treatment can address:
- Deep Smile Lines and Laugh Lines: Reduce the appearance of static lines that run from the nose to the corners of the mouth.
- Volume Loss: Restore lost volume in the mid-face, improving support and reducing sagging.
- Facial Asymmetry: Balance uneven folds or creases for a more symmetrical look.
- Crease Reduction: Smooth stubborn nasolabial and marionette lines without overfilling.
- âFold Prevention: Treat early fine lines before they develop into deeper folds.
Our filler treatments are personalised to your facial anatomy and aesthetic goals to ensure subtle, balanced, and age-appropriate enhancements.
How Does Nasolabial Fold Filler Treatment Work?
We use hyaluronic acid dermal fillers, a naturally occurring substance in the skin known for its ability to attract and retain moisture. When we inject this type of filler into the nasolabial fold, it fills the crease, smooths the area, and supports surrounding skin structures.
â
Hereâs how our approach differs:

Advanced Techniques
We use a combination of needle and cannula methods to precisely place the filler used, minimising trauma and ensuring even distribution.

Facial Mapping
Each filler treatment is guided by your individual bone structure, fat pads, and skin elasticity for the most natural look.

Layered Approach
We may also treat adjacent areas like the cheeks to better restore lost volume and enhance the outcome of the nasolabial correction.
Unlike Botox, which relaxes muscles, fillers add volume and physically smooth the skin. Youâll see immediate improvement with optimal results emerging over the following week.
Treatment Overview
Your journey with treatment begins with an in-depth consultation at our London clinic.

During this session, we
- Assess your skin condition, fold depth, and volume status
- Discuss goals, ideal type of filler, and treatment timeline
- Create a personalised treatment plan for optimal facial rejuvenation
Each injection session lasts about 30â45 minutes. A topical anaesthetic may be applied to improve comfort. You may feel a light pressure or pinch during the injection process.

Aftercare
slight swelling or redness may occur but typically resolves within 48 hours. Most patients resume normal activities immediately.
How Long Do Nasolabial Fillers Last?
The longevity of fillers depends on factors such as the type of filler used, your metabolism, and skincare routine. Typically, results last:
- 9 to 18 months with hyaluronic acid fillers
- Maintenance sessions recommended once a year
Our team will advise you on when to return for top-ups based on how your body metabolises the hyaluronic filler and how your smile lines evolve.

Discover StoryFrequently Asked Questions
What is a nasolabial fold filler?
It is a type of dermal filler injection used to treat the lines running from the nose to the corners of the mouth. It restores volume and smooths the folds to achieve a more youthful, refreshed appearance.
Most clients find the treatment comfortable. We apply a topical anaesthetic before the injection, and most fillers used also contain lidocaine to enhance comfort throughout the procedure.
Whatâs the difference between filler and Botox?
Botox relaxes muscles to prevent wrinkles caused by movement. Filler, on the other hand, adds volume and fills in static lines such as smile lines or nasolabial folds.
Absolutely. Our goal is to smooth the creases while maintaining your natural expressions. We avoid overfilling and focus on subtle enhancement that restoresânot changesâyour features.
What aftercare is required?
Avoid strenuous exercise, alcohol, or facial treatments for 24 hours post-injection. Minor swelling or bruising may occur. Full results are visible within 7 days.
Why choose your clinic for nasolabial filler in London?

How do I know if I need a filler for nasolabial folds?
If youâve noticed deepening of nasolabial foldsâthe lines that run from the sides of the nose to the corners of your mouthâor if you feel these lines make you look tired or older than you feel, a nasolabial fold filler treatment may be ideal.Â
Are dermal fillers for nasolabial folds safe?
Yes, dermal fillers are injectable treatments that are generally very safe when administered by qualified professionals. At our clinic, we only use premium hyaluronic acid-based filler products that are biocompatible and reversible.
How long does the nasolabial fold filler procedure take?
The nasolabial fold filler procedure typically takes 30 to 45 minutes, including consultation, facial analysis, and the filler injections themselves. Thereâs no need for anaesthesia beyond a topical numbing cream, and thereâs little to no significant recovery time required.
Can dermal fillers be combined with other treatments?
Absolutely. Many patients combine filler for nasolabial folds with complementary treatments like cheek filler (to lift the mid-face), lip filler, or chin filler for improved facial symmetry. In some cases, we may also recommend line filler for fine lines and wrinkles around the mouth.Â
What are the long-term benefits of nasolabial fold fillers?
Beyond the immediate improvement in the appearance of smile lines or laugh lines, nasolabial fillers can also stimulate collagen production in the treated area, leading to firmer, more youthful skin over time. While results vary depending on the type of filler used, many patients report that nasolabial folds become less pronounced even after the filler has been absorbed.
