Masseter Reduction

A masseter reduction slims the jawline for a softer, more rounded face shape. This is done by injecting the masseter muscles with a temporary muscle relaxer such as botulinum toxin.

What is a Masseter Reduction?

The masseter is a muscle located between the cheekbone and the lower jaw, and is primarily used for chewing food. Strong masseter muscles (a potential result of genetics or medical conditions such as bruxism) can lead to a wide, square-shaped jaw.

To slim and reshape the jawline, a masseter reduction involves the injection of the temporary muscle relaxer botulinum toxin. Botox, Azzalure, Dysport and Xeomin are all types of botulinum toxin (or ‘botox injections’ as they’re often referred to).

This procedure can also be used to treat medical issues such as habitual teeth grinding (bruxism), jaw clenching and tension headaches.

How Does a Masseter Reduction Work

A masseter reduction works by relaxing the masseter muscles using an injectable such as Botox. This temporarily freezes the muscle, which in turn weakens and reduces its mass and size. The result is a slimmer, softer, more oval-shaped jaw line.

A non-invasive cosmetic procedure, a masseter reduction should take just 10 to 15 minutes to perform, and results generally last around six months. For best results, we recommend that patients receive a second treatment around eight weeks after their first.

Who Can Benefit from a Masseter Reduction?

A masseter reduction may prove beneficial for anyone that feels unhappy with the size or shape of their jawline but wants to avoid surgical fixes. A masseter reduction can provide a more balanced facial shape and a slimmer, more oval-shaped jawline with just a few injections.

A masseter reduction can also offer relief from bruxism (habitual teeth grinding), and related issues such as temporomandibular disorder (TMD) and tension headaches. Weakening the masseter through this treatment relaxes the jaw and prevents symptoms such as head and ear pain, tooth damage, a tight or locked jaw, and more.

The Advantages of Masseter Reduction

A masseter reduction is the only way of reducing the shape and size of the jawline without surgery. A non-invasive cosmetic surgery, it takes just 15 minutes and with very little pain, no downtime and no long-lasting side effects such as not being able to eat.

Other benefits of a masseter reduction include:

Balancing the facial shape by reducing the size of the jawline and creating a more soft, oval shape.

Providing relief for conditions such as bruxism (habitual teeth grinding), temporomandibular disorder (TMD) and tension headaches, as well as their symptoms.
