What Is Masseter Botox?
Masseter Botox is a non-surgical injectable treatment that targets the masseter muscles, which are responsible for chewing and jaw movement. When these muscles become enlarged due to genetics, teeth grinding, or chronic jaw clenching, they can create a wide or square-looking lower face. By relaxing the masseter muscles, Botox helps slim the jawline and soften facial contours.
