Jaw Reduction Treatment in London
Achieve a Slimmer, More Defined Jawline
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 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.

What is Jaw Reduction with Botulinum Toxin?
A strong, bulky masseter muscle can lead to a square jawline and excessive teeth grinding (bruxism). Botulinum toxin injections help by:
✔ Relaxing the masseter muscle, reducing its size over time
✔ Creating a slimmer, more contoured jawline
✔ Minimising excessive clenching & grinding, reducing jaw tension
✔ Enhancing facial balance & cheek definition
This procedure is also known as the Botox V-shape treatment, as it softens the lower face for a more feminine, refined appearance.
Benefits of Jaw Reduction Treatment
✅ Slimmer jawline – Reduces the width of the lower face for a contoured look
✅ Non-surgical & minimally invasive – No downtime, no incisions
✅ Relieves teeth grinding (bruxism) – Reduces pressure, preventing jaw pain & enamel wear
✅ Balances facial proportions – Enhances the cheekbones for a more sculpted appearance
✅ Quick & effective – The procedure takes 20–30 minutes with no recovery time
