What is Bruxism & Jawline Slimming treatment?
Bruxism involves jaw clenching/grinding, often enlarging the masseter muscles over time and creating a wider lower face. By carefully relaxing these muscles, we aim to ease clenching-related tension and soften jaw width, giving a slimmer, more V-shaped appearance—without surgery and while preserving natural function. Your plan can be combined with dentist-advised measures (e.g., night guards) if appropriate.

Frequently Asked Questions
Procedure
The appointment duration is 30 mins. We use very fine needles to administer the Botox into the desired muscle area which are relatively painless and no numbing required.
Duration & Longevity
Optimum results will be experienced within two weeks following the treatment. Botox on average lasts around 3-4 months after which the muscles resume their normal activity.
Downtime
There is no downtime needed and can return to normal activities. You may have small raised blebs on the skin but these settle within 30 mins. Common side effects are slight bruising, mild headache/tenderness in the injection sites but this is all temporary. Post treatment- stay upright for 4-6hours so that botox doesn’t migrate and no facials/massages for 2 weeks.
Common misconceptions
Clients often become concerned with botox and the ‘frozen’ look. I will adjust the dosing appropriate for the type of look the client wants.
Botox treatment is best done preventatively and the most people assume botox should be done when the lines are present at rest. It’s best to start earlier before the lines on the forehead become fixed at rest in order to maintain a smoother youthful appearing skin.
