Jaw Slimming in London

Jaw slimming uses botulinum toxin to relax the masseter muscles at the angle of the jaw, which over time can soften a square or bulky jawline for a slimmer, more contoured appearance. It is also often used to help ease jaw tension and teeth grinding.

Results typically last around four to six months, though this varies with your muscle strength and how your body responds. Many clients return for maintenance treatments to sustain their result.

Prices start from £350 at our Mayfair clinic, with your exact cost confirmed at your consultation. The final cost depends on the amount of product needed for your individual muscles.

By relaxing the masseter muscles, this treatment can help reduce the tension associated with teeth grinding and jaw clenching for many people. We will assess your symptoms at your consultation to see whether it may be suitable for you.

Any tension relief can be felt within the first week or two, while the visible slimming effect develops more gradually over several weeks as the muscle softens. We often arrange a review to check your progress.

The treatment involves a few injections into the jaw muscles and most clients find it very manageable. Please raise any concerns about comfort at your consultation.

Side effects are usually mild and temporary and can include slight bruising, swelling or tenderness when chewing for a short while as the muscle adjusts. We will go through full aftercare guidance with you.

Some people notice a change after one treatment, while a slimmer contour often develops over a course of sessions as the muscle gradually reduces in size. We will recommend a plan tailored to you at your consultation.

There is generally little to no downtime and most people return to their normal routine straight away. We do ask you to follow some simple aftercare advice for the first few hours.

It suits many people with enlarged masseter muscles or jaw tension, but it is not suitable if you are pregnant or breastfeeding or have certain medical conditions, and it cannot be given to anyone under 18. We will confirm your suitability at your consultation.
