What Are Nasolabial Folds and Marionette Lines?
Nasolabial folds, often called ‘smile lines’ or ‘laugh lines’, are the creases that run from the sides of the nose to the corners of the mouth. Marionette lines extend downwards from the corners of the mouth to the jawline. While a natural part of facial anatomy, they can deepen over time, creating a tired or aged appearance.
The primary cause of prominent nasolabial folds and marionette lines is the natural ageing process. As we age, our skin’s production of collagen and elastin—the proteins responsible for firmness and elasticity—declines significantly. Simultaneously, we experience a loss and redistribution of facial fat, particularly in the mid-face and cheek area. This loss of structural support causes the skin to sag downwards, making these facial wrinkles more pronounced. Other contributing factors that can accelerate this process include genetics, significant sun exposure, lifestyle choices like smoking, and repetitive facial expressions. At Rejuva London, we use expertly administered Nasolabial Fold Fillers to restore this lost volume, soften the appearance of these lines, and rejuvenate the lower face for a naturally refreshed and youthful look.
How Do Dermal Fillers Restore and Regenerate Volume?
At Rejuva London, our philosophy extends beyond simply filling lines; we focus on genuine facial restoration. Dermal fillers are not just about adding volume but about strategically replenishing the face’s natural architecture. The most common fillers are composed of hyaluronic acid (HA), a substance that occurs naturally in the body, which draws moisture to the area, providing immediate support and hydration to lift and smooth the skin.
However, our advanced, doctor-led approach embraces the next generation of aesthetic treatments: bio-stimulatory fillers. Unlike traditional HA fillers that primarily provide volume, bio-stimulators such as Sculptra and Radiesse work by activating your body’s own regenerative capabilities. When injected, these products create a scaffold beneath the skin, triggering a process called neocollagenesis—the production of new, strong collagen and elastin fibres. This means that over the weeks and months following your treatment, your skin rebuilds its own youthful structure from within. The result is not only the softening of facial wrinkles but a progressive and long-lasting improvement in skin quality, texture, and firmness. This regenerative technique, a specialism of Dr. Kristy Lau, ensures results are exceptionally natural, restorative, and align with our commitment to subtle, elegant enhancements rather than artificial-looking changes.
Are You a Suitable Candidate for Smile Line Fillers?
An effective smile lines treatment is suitable for a wide range of individuals seeking to address the signs of ageing in the lower and mid-face. You may be an ideal candidate if you have noticed that your smile lines or nasolabial folds are visible even when your face is at rest, contributing to a tired or sad appearance. This treatment is highly effective for those experiencing mild to moderate volume loss in the cheeks, which can exacerbate the depth of these folds.
Ideal candidates are adults in good overall health who have realistic expectations about the outcomes of a non-surgical procedure. They are looking for a significant, yet natural-looking improvement rather than a complete transformation. This treatment is perfect for those who wish to achieve a refreshed, more youthful look without the downtime and risks associated with surgery. During your comprehensive consultation with Dr. Kristy Lau, she will conduct a holistic facial assessment to determine if nasolabial fold filler is the most appropriate treatment for your unique anatomy and aesthetic goals. In some cases, addressing volume loss in the cheeks first may provide the best and most natural-looking lift, a testament to our doctor-led, patient-first approach.
Your Doctor-Led Treatment Journey on Harley Street
Your safety and comfort are the cornerstones of the Rejuva London experience. Your journey begins with a thorough, one-on-one consultation with our highly esteemed Medical Director, Dr. Kristy Lau. With decades of medical experience and advanced training from Imperial College London, Dr. Lau conducts a meticulous facial analysis, discussing your concerns and aesthetic aspirations to create a bespoke treatment plan tailored precisely to you.
The dermal filler treatment itself is performed with the utmost precision and care in the pristine, clinical environment of our Harley Street clinic. To address the common question, “Are smile line fillers painful?”, we prioritise your comfort at every stage. A topical anaesthetic cream is applied to the treatment area to minimise sensation, and the premium fillers we use contain a local anaesthetic (lidocaine) for a virtually painless experience. Dr. Lau employs advanced injecting techniques, often using a cannula where appropriate, to reduce the risk of bruising and swelling, ensuring a smoother recovery. This doctor-led protocol guarantees that your procedure is not only effective but is performed under the strictest medical safety standards, providing you with the ultimate peace of mind that you are in the hands of a true expert.
What Natural-Looking Results Can I Expect and How Long Do They Last?
The goal of our anti-aging fillers is to restore and refresh, not to alter your natural appearance. Immediately following the treatment, you will notice a visible softening of the nasolabial folds and a subtle lift in the mid-face. The results are designed to be elegant and harmonious with your facial features, leaving you looking rested and rejuvenated, as if you’ve just returned from a relaxing holiday. Friends and family may notice you look well, but the treatment itself will be imperceptible.
The longevity of your results depends on several factors, including the type of filler used, your individual metabolism, and lifestyle. At Rejuva London, we use only premium, FDA-approved dermal fillers renowned for their quality and durability. You can typically expect the beautiful, natural-looking results to last between 9 to 18 months. For those who opt for bio-stimulatory fillers, the collagen-building effects can provide a longer-lasting improvement in skin quality. Dr. Lau will recommend a personalised maintenance plan during your consultation to ensure you enjoy your refreshed appearance for as long as possible.

| Bio-Stimulatory Fillers | CaHA or PLLA | 18 – 24+ Months | Long-term collagen stimulation and skin firming |
Risks & Aftercare: Ensuring a Safe and Smooth Recovery
While nasolabial fold filler is a minimally invasive procedure with an excellent safety profile when performed by a qualified medical doctor, it is important to be aware of potential side effects. The most common reactions are temporary and mild, typically resolving within a few days. These include redness, swelling, tenderness, and bruising at the injection sites. Lumps or bumps may occasionally be felt under the skin, which usually smooth out on their own over a week or two.
More serious complications, though very rare, can include infection, allergic reaction, or vascular occlusion (where filler is inadvertently injected into a blood vessel). The extensive anatomical knowledge and precise injection techniques of an expert like Dr. Kristy Lau significantly mitigate these risks. To ensure a smooth recovery and optimal results, we provide comprehensive aftercare instructions. We advise patients to avoid strenuous exercise, excessive sun or heat exposure, and alcohol for 24-48 hours post-treatment. It is also recommended to avoid applying firm pressure to the treated area for the first few days. Adhering to this guidance will help minimise swelling and allow the filler to settle perfectly into place, ensuring a beautiful, safe outcome.

Your Questions Answered: Nasolabial Fold Filler FAQs
Do dermal fillers work for smile lines?
Yes, dermal fillers are exceptionally effective for treating smile lines, also known as nasolabial folds. By precisely restoring lost volume with a sophisticated hyaluronic acid-based gel, fillers can soften the crease, smooth the surrounding skin, and create a more refreshed, natural-looking facial contour.
A successful outcome relies on a detailed facial assessment by an experienced medical professional to determine the optimal filler type and placement for your unique anatomy.
Are nasolabial fold filler treatments painful?
Most patients report minimal discomfort during nasolabial fold filler treatments. At our Harley Street clinic, Dr. Kristy Lau uses premium dermal fillers that contain a local anaesthetic (lidocaine) to enhance your comfort, and a topical numbing cream is applied beforehand to ensure the procedure is as gentle as possible.
You may feel a slight pinching sensation upon injection, but the procedure is generally very well-tolerated.
What type of filler is best for nasolabial folds?
The most suitable fillers for nasolabial folds are typically based on hyaluronic acid (HA), a substance that naturally provides hydration and volume in the skin. For certain patients, Dr. Lau may recommend collagen-stimulating fillers (bio-stimulators) to encourage long-term skin regeneration and structural support.
The choice is entirely bespoke, tailored to your skin quality and aesthetic goals during your comprehensive, doctor-led consultation.
Is there any downtime after the treatment?
There is typically no significant downtime following nasolabial fold filler treatment, allowing most patients to resume their normal activities immediately. You may experience some mild, temporary redness, swelling, or bruising at the injection sites, which usually resolves within a few days.
We provide all patients with thorough aftercare instructions to minimise these effects and ensure a smooth, swift recovery.
Can fillers help prevent marionette lines from forming?
While fillers primarily treat existing lines, a strategic and holistic treatment plan can help prevent the worsening of marionette lines and other facial wrinkles. By supporting the mid-face structure and stimulating your own collagen, treatments can proactively maintain a youthful contour and delay the formation of deeper folds.
This preventative approach is a cornerstone of our doctor-led philosophy, focusing on long-term, natural-looking rejuvenation.
How much do nasolabial fold fillers cost in London?
The cost of nasolabial fold filler treatment is tailored to each individual, as it depends on the specific type and volume of product required to achieve your desired result. At our Harley Street clinic, a clear and transparent pricing structure will be discussed during your initial consultation with Dr. Lau.
This ensures your investment is precisely aligned with a bespoke treatment plan designed to meet your unique aesthetic goals.
