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.

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
Jaw Reduction Treatment Showcase
Our jaw reduction treatment delivers noticeable yet natural-looking results:
  • Slimmer jawline – Gradual reduction in masseter muscle size creates a more contoured lower face
  • Reduced jaw tension – Decreased muscle activity relieves symptoms of teeth grinding and clenching
  • Enhanced facial harmony – Improved balance between the upper, mid, and lower face
  • Natural-looking results – Subtle refinement that enhances your natural features
Results develop gradually over 2-4 weeks after treatment, with maximum effect visible by 6-8 weeks. The slimming effect typically lasts 4-6 months, after which a maintenance treatment is recommended.

Frequently Asked Questions

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.

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.

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.

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.

Yes, jaw reduction treatment works excellently alongside other facial contouring procedures. Many clients combine it with:
During your consultation, we can create a comprehensive treatment plan tailored to your aesthetic goals.
For optimal results, we recommend:
  • 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
Some clients with very strong masseter muscles may require more frequent treatments initially, with longer intervals between maintenance sessions as the muscle adapts.
