Jaw Reduction Treatment in Marylebone, London
Non-Surgical Jaw Slimming at Mesglo Aesthetic Clinic in Marylebone, London
A wide or square jawline can result from an enlarged masseter muscle, which is responsible for chewing and jaw clenching. While this can be a desirable feature for men, some individuals seek a softer, more contoured lower face. At Mesglo Clinic in Marylebone, London, we offer non-surgical jaw reduction using botulinum toxin (Botox) to slim the jawline, reduce teeth grinding (bruxism), and create a more balanced facial shape.
Raheena is friendly, professional, and knowledgeable. She made me feel comfortable, listened to what I wanted, and gave me great advice. The treatment was smooth, and I love the results. Highly recommend!

Frequently Asked Questions
HOW DOES JAW REDUCTION TREATMENT WORK?
Botulinum toxin is precisely injected into the masseter muscles (the strong chewing muscles at the angle of the jaw). This temporarily relaxes the muscle, reducing its activity and size over time. As the muscle becomes less bulky, the jawline appears slimmer and more contoured, creating a more oval facial shape.
IS THE TREATMENT PAINFUL?
Most clients report minimal discomfort during the procedure. We use ultra-fine needles and can apply a topical numbing cream if needed. The sensation is often described as a slight pinch that lasts only a few seconds per injection.
WHEN WILL I SEE RESULTS?
You may notice initial changes within 1-2 weeks as the muscle activity begins to decrease. However, the full slimming effect develops over 6-8 weeks as the masseter muscle gradually reduces in size. For optimal results, some clients may require a second treatment session.
WILL JAW REDUCTION AFFECT MY ABILITY TO CHEW?
No, the treatment is carefully calibrated to reduce excessive muscle activity while maintaining normal function. You will still be able to chew normally, but the excessive clenching force is reduced. This actually benefits many clients who experience jaw tension or teeth grinding.
CAN I COMBINE THIS WITH OTHER TREATMENTS?
- Chemical Brow Lift for upper face rejuvenation
- Cheek Enhancement for mid-face volume
- Chin Enhancement for improved profile
- Anti-Wrinkle Treatments for overall facial rejuvenation
HOW MANY TREATMENTS WILL I NEED?
- Initial Phase: 1-2 treatments spaced 4-6 weeks apart to achieve desired jawline reduction
- Maintenance: Follow-up treatments every 4-6 months to maintain results
