Reviews for our Face shaping (masseter jaw reduction) treatment
What is jaw slimming botox treatment like?

Aesthetic and medical benefits
Botox injections gently relax the masseter muscle, softening the shape of your jawline and reducing bruxism (teeth grinding), combatting the painful symptoms of TMJ disorder and damage to your teeth.
Pre-treatment consultations
Before your treatment you will meet with one of our medical practitioners to discuss the results you’re hoping for. They’ll ask you about your medical history to ensure that this treatment is safe and appropriate for you.
During your treatment
Your practitioner will administer carefully targeted injections into your masseter muscle. This causes relaxation in specific muscles, and triggers others to tighten and lift the jawline.
You may feel a slight stinging sensation as the botox is injected, but this is only momentary.
Usually patients require two botox treatments, eight weeks apart, to achieve the desired effect.
