What is Masseter Botox?
Masseter Botox (jaw botox) is a non-surgical treatment that involves injecting small amounts of botulinum toxin type A (Botox) into the jaw muscles. The masseter muscle is responsible for chewing, and when it is overdeveloped, it can cause a wide, square-shaped jawline, which may be undesirable for some people.
By injecting Botox into the masseter muscle, it relaxes the muscle and reduces its size, resulting in a slimmer, more contoured jawline.
How Masseter Botox Works
Masseter botox works by injecting into the muscles in your face to block the nerve signal so that the muscle is unable to move.
The procedure is relatively simple and can be done in a medical professional’s office. The treatment itself takes only a few minutes, and the botox results typically last for 3-6 months. After the treatment, patients can resume their normal activities immediately, and there is no recovery time required.
