Jaw Slimming/Masseter Reduction

The masseter is one of the muscles that helps you chew it’s located on the side of your face.

When Botox is injected into the masseter, it’s called a masseter Botox. It’s sometimes called jaw Botox. The treatment uses botulinum toxin to temporarily block nerve signals in the masseter. As a result, the muscle is unable to move.

This is a very popular treatment for those suffering from bruxism/TMJ dysfunction. It can also help in those patients wishing to create the illusion of a slimmer lower face. I have performed hundreds of masseter Botox injections.






6 - 12 MONTHS


When you arrive at your appointment, your provider will talk you through the process. You may be asked to lie down on your back, though some providers will perform this procedure with you sitting up. They may apply a topical anesthetic, like lidocaine. Next, we’ll use a thin, sterilised needle to inject Botox into the skin around the sides of your nose. This procedure will typically require multiple injections, but it shouldn’t take long.


Side effects from botulinum toxin injections vary depending on the area receiving treatment. Most issues are mild and improve in a day or two. Possible Botox side effects include pain, swelling, redness or bruising at the treatment site.
