Jaw Reduction Treatment London - Masseter Slimming Marylebone
Jaw reduction treatment at Mesglo London in Marylebone, London uses botulinum toxin injections to slim and refine the jawline by reducing the masseter muscles. This non-surgical treatment is ideal for those with a square or wide jaw who desire a more V-shaped, elegant facial contour. It is also highly effective for treating bruxism (teeth grinding) and the associated jaw pain, tension headaches, and dental wear that accompany this condition.
Price: From £300 | Duration: 20-30 minutes | Results: Gradual slimming over 4-6 weeks
What Is Masseter Jaw Reduction?
The masseter is a powerful chewing muscle located at the angle of the jaw. In some individuals, this muscle is naturally larger or becomes hypertrophied (enlarged) through habitual teeth clenching, grinding, or chewing. When the masseter is overdeveloped, it creates a square, wide, or heavy jaw appearance that can make the face look broader than desired.
Botulinum toxin injections into the masseter muscle cause it to gradually reduce in size over 4–6 weeks. The result is a slimmer, more V-shaped jawline and a softer, more refined facial contour. For clients with bruxism, the treatment also significantly reduces the force of jaw clenching, providing relief from jaw pain, headaches, and tooth sensitivity.

Who Is a Good Candidate?
Jaw reduction treatment is suitable for adults who are bothered by a square or wide jaw due to masseter hypertrophy, those who suffer from bruxism or jaw clenching, and anyone seeking a more defined, V-shaped facial contour without surgery. It is equally popular with both men and women, and is particularly effective for those of East Asian heritage where masseter hypertrophy is more prevalent.
A thorough consultation at our Marylebone clinic will assess your masseter size, jaw anatomy, and facial proportions to determine the optimal dosage and injection technique for your goals. For those also seeking jawline definition, our practitioners may recommend combining jaw reduction with cheek enhancement or chin and jawline dermal fillers for a comprehensive facial contouring result.
The Treatment Process
- Detailed consultation and masseter assessment
- Palpation of the masseter muscle to determine size and injection points
- Precise marking of injection sites
- Targeted botulinum toxin injections into the masseter muscles
- Post-treatment care instructions
- Follow-up assessment at 4–6 weeks to review results
Aftercare and Recovery
There is no downtime after jaw reduction treatment. You may experience mild tenderness at the injection sites for 24–48 hours. We advise avoiding chewing hard foods, strenuous exercise, and applying pressure to the jaw area for 24 hours post-treatment. The slimming effect develops gradually over 4–6 weeks as the masseter muscle reduces in size.
Long-Term Results
With repeated treatments, the masseter muscle gradually and permanently reduces in size. Many clients find that after 2–3 treatment cycles, the muscle remains smaller and they require less frequent maintenance appointments. This cumulative reduction effect makes jaw reduction one of the most cost-effective non-surgical facial contouring treatments available.
Frequently Asked Questions
How long do jaw reduction results last?
Results typically last 4–6 months initially. With regular treatments, the masseter muscle gradually reduces in size, and many clients find they need less frequent treatments over time as the cumulative effect builds.
Is jaw reduction treatment painful?
The treatment involves minimal discomfort. We use fine needles and the procedure is quick, typically taking 20–30 minutes. Most clients describe the sensation as a mild pinch. Topical numbing cream is available on request.
Will jaw reduction affect my ability to chew?
No. The treatment reduces the size of the masseter muscle but does not eliminate its function. Normal chewing is unaffected. The reduction in muscle force is only noticeable in the context of hard chewing or clenching, where it provides relief from bruxism symptoms.
Can jaw reduction be combined with other treatments?
Yes. Jaw reduction is frequently combined with cheek enhancement, chin fillers, and anti-wrinkle injections for a comprehensive facial contouring and rejuvenation result. Our practitioners will design a bespoke treatment plan during your consultation.
