Jaw slimming, also known as masseter reduction or facial slimming, is one of the most popular non-surgical facial contouring treatments at Mesglo Aesthetic Clinic Marylebone, London. Botulinum toxin injections into the masseter muscles reduce their bulk over time, creating a slimmer, more oval facial profile without surgery or downtime.

What Is Masseter Reduction?
The masseter is a large chewing muscle at the angle of the jaw. In some individuals, the masseter is hypertrophied (enlarged), either naturally or due to teeth grinding (bruxism), creating a square or wide jaw appearance. Botulinum toxin injections cause the muscle to atrophy gradually, resulting in a visibly slimmer jawline over 4 to 8 weeks.

Frequently Asked Questions
Who is a good candidate for jaw slimming?
Jaw slimming is suitable for patients who wish to achieve a more oval or heart-shaped facial profile, those with masseter hypertrophy from bruxism, and patients seeking facial feminisation without surgery. It is not appropriate for patients with very thin facial tissue or those whose jaw width is primarily skeletal rather than muscular.
How long do results last?
Initial results from masseter botulinum toxin are visible at 4 to 6 weeks and peak at 8 to 12 weeks. Results typically last 4 to 6 months, after which the muscle gradually returns to its original size. With repeated treatments, the masseter often remains smaller for longer periods. Most patients maintain results with 2 treatments per year.
