Anti-wrinkle to this area is a fantastic way to treat concerns of teeth grinding (bruxism), and Jaw clenching. These conditions are typically responsible for head aches and dental problems. Anti-wrinkle treated at the back of the jaw will help relax the muscle responsible (masseter muscle) and relieve tension to the area, this will help reduce the effects of bruxism and jaw clenching. Another benefit of anti-wrinkle to the masseter muscle is, as it relaxes, it also creates a more slimming result. The procedure is referred to as ‘masseter reduction’. Typically, people who suffer from bruxism, tend to have strong masseter muscles resulting in a strong square jaw line. Injecting this muscle reduces its activity which can have a dramatic slimming effect on the contour of the face.
