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 for masseter jaw reduction – your questions answered

Who is botox for masseter jaw reduction for?

Non-surgical jaw reduction, or jaw botox as it is sometimes called, is a very popular treatment for female patients who wish to recontour a strong jawline or wider lower face, to achieve a more feminine, oval shaped face. 

Botox treatment to reduce the masseter muscle is also helpful for male patients who wish to soften a strong, wide or square jawline.

This method achieves face reshaping without the need for surgical intervention and its associated risks and expense.

How does botox for masseter jaw reduction work?

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. 

What is the science behind botox for masseter jaw reduction?

Botulinum toxin or ‘botox’ works by blocking the release of acetylcholine, a neurotransmitter that triggers muscle contraction.

By inhibiting acetylcholine release, botox temporarily relaxes the masseter muscle, reducing its ability to contract.
