What causes smile lines

Nasolabial folds are not really lines in the skin. They are a shadow cast by volume that has moved or been lost above them.

The nasolabial folds, commonly called smile lines, run from the side of the nose to the corners of the mouth. They deepen as the face loses volume with age, and they can appear earlier after significant weight loss or with sun damage. Repeated expression sets them further in over time.

Hyaluronic acid filler treats them by replacing the volume that has been lost, which lifts the skin and softens the shadow. It also helps prevent the fold becoming a static line, one that stays visible even when your face is completely at rest.

The treatment takes no longer than 10 minutes and results are immediate, so you can go straight back to your normal day. Every appointment starts with a consultation and assessment so we understand what you want before anything is placed.

The fold is often not where the problem is

Filling a deep nasolabial fold directly is the obvious move and frequently the wrong one. If the fold is deep because the cheek above it has lost support, treating the fold alone leaves a heavy result that looks filled rather than lifted.

We assess the mid-face as a whole before deciding where product goes. Sometimes the answer is cheek support with very little in the fold itself, and that is a conversation worth having before you commit to a treatment.

What to expect during your treatment.

01

Consultation

A detailed consultation assesses your facial structure, skin quality and the depth of your folds. We discuss the outcome you want and build a personalised plan, including whether the fold or the cheek above it is the right target.

02

Treatment

Numbing cream is applied and treatment only begins once the area is numb. Premium hyaluronic acid filler is placed into the folds to restore volume and soften the lines. It takes around 10 minutes.

03

Aftercare

Results are visible immediately and continue to settle over the following days. Mild swelling, redness or tenderness is common and usually resolves within a few days. No recovery time is needed.

Who is a suitable candidate?

Smile line treatment suits you if the folds beside your mouth have deepened enough to be visible when your face is at rest.

The lines from your nose to your mouth are visible when you are not smiling
Volume loss or weight loss has deepened the folds
You want softening rather than complete removal
You want a reversible treatment rather than a permanent one
You are in good general health, 18 or over, with realistic expectations
You are not currently pregnant or breastfeeding

If we think the fold is not the right place to treat, or that the result would look overfilled, we will tell you and explain what would work better.

Questions, answered.

Dermal filler is injected strategically into the smile lines to restore lost volume and soften their appearance. Results are instant and the treatment takes around 10 minutes.

Numbing cream is applied to the area and treatment only starts once it is numb, making the experience as comfortable as possible. Most patients report minimal discomfort.

We start with a thorough consultation to understand your requirements and confirm your suitability. Once we have a full assessment and you are happy to proceed, we carry out the treatment.

No recovery time is needed. You can return to your daily routine straight away without taking time off work.

Typically 12 to 18 months, depending on the product used, the amount placed and individual factors such as metabolism and lifestyle.

Unlike surgery, this treatment is fully reversible. The filler can be dissolved, allowing the area to return to its original form.

It can if it is overdone or placed in the wrong position. We assess the cheek and mid-face as well as the fold itself, and often the better result comes from using less product in the fold than you might expect.

We are known for natural-looking results and honest assessment. If we do not think a treatment is suitable for you, we will not recommend it.

Look forward to the best version of you.
