The Jaw Muscles
Botox for the Jaw Muscles (Masseter Muscles)
BOTOX® Cosmetic to slim the face: Some patients have very active jaw muscles that give their face a very square shape. These are called the masseter muscles and are the main muscles used for chewing and biting. Injecting BOTOX® Cosmetic in these muscles can reduce their size and give a square face a much more tapered or oval appearance.
