Masseter slimming is a doctor-led treatment designed to reduce excessive activity and bulk in the jaw muscles.
It can gradually create a slimmer, softer lower-face appearance while also helping selected patients who experience jaw clenching or teeth grinding.
What is the masseter muscle?
The masseter is one of the main muscles used for chewing. It sits at the angle of the jaw and can become enlarged through genetics, frequent clenching, bruxism or habitual chewing.
What can masseter slimming improve?
- A slimmer-looking lower face
- Softer jaw angles
- Improved facial balance
- Reduced jaw-muscle bulk
- Less jaw tension
- Improvement in selected cases of clenching or teeth grinding
The treatment does not remove bone or facial fat. It works by gradually relaxing excessive muscle activity, allowing an enlarged masseter muscle to become less prominent over time.
Can it create a V-shaped face?
For suitable patients, reducing masseter-muscle bulk can create a softer and more V-shaped lower face. It is most effective when lower-face width comes from enlarged jaw muscles rather than bone structure, facial fat or skin laxity.
When will results appear?
Jaw tension may begin to improve before facial slimming becomes visible. The muscle gradually becomes less bulky over the following weeks, creating a progressive and natural-looking change.
Will the result look natural?
Yes. The aim is not to weaken the face excessively or create an unnatural appearance. The doctor assesses the strength, size and symmetry of both muscles before tailoring the treatment.
Can it be combined with other treatments?
Depending on anatomy and goals, masseter slimming may be combined with jawline lifting, chin refinement, Ultraformer MPT, skin tightening or collagen-stimulating treatments.
Why choose a doctor-led treatment?
The masseter is a powerful functional muscle involved in chewing and jaw movement. Accurate assessment and placement are essential. At London Finsbury Clinic, treatments are performed by a doctor and personalised according to facial anatomy, muscle strength, symmetry and the desired result.
