Face shaping (masseter jaw reduction)
Botox treatment for masseter jaw reduction reshapes the lower face to achieve softer, more rounded proportions.
The masseter muscle is a major facial muscle located in the jaw that is associated with chewing and teeth grinding.
An enlarged masseter muscle can result in a wide or square jawline, which some patients consider to be more masculine, or too prominent.
Through targeted botox injections, the masseter muscle reduces in size, thereby recontouring the jawline to achieve a more oval shape, and overall balance in facial features.

What is botox for masseter jaw reduction 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.

Botox injections are targeted into the masseter muscle, which causes it to relax and reduce in size, therefore changing the physical mass of the muscle and making it less prominent.
