The Treatment
Masseter reduction uses anti-wrinkle injectable to gently relax the masseter muscle, the strong chewing muscle at the angle of the jaw, slimming a square jawline into a softer, more contoured shape.
It's a popular treatment for clients whose jaw looks wider due to overactive muscles, or who experience tension and clenching in the jaw.
Over a few weeks the muscle gradually reduces in size, revealing a slimmer lower face while preserving your natural movement.
What It Treats
Every treatment at Amy-Lucy Clinic & Academy is bespoke to you, designed around your features, your goals, and your comfort. Delivered from our Brentwood clinic in the heart of Essex.

The Process
STEP 01
Amy-Lucy assesses your jawline and masseter muscle to determine the right dose and confirm suitability.
STEP 02
A precise amount of product is placed into the masseter muscle on each side, with minimal discomfort.
STEP 03
Over 4 to 6 weeks the muscle gently reduces in size, revealing a softer, slimmer jawline.
Why Choose Amy-Lucy Clinic in Essex
Anti-wrinkle injections are one of the most popular aesthetic treatments in the UK, and at Amy-Lucy Clinic in Brentwood, Essex, every treatment begins with a thorough consultation to understand your concerns, your facial anatomy, and the result you're hoping to achieve.
