An enlarged masseter muscle can create a bulky or square jawline and may be associated with teeth grinding or jaw clenching. Overactivity in this muscle can also contribute to jaw tension, headaches, and facial discomfort.
Botox reduces the strength of the masseter muscle by limiting excessive contraction. Over time, this allows the muscle to slim down, creating a softer jawline and more balanced facial shape.
In addition to aesthetic benefits, masseter Botox often provides functional relief for patients who experience jaw pain or bruxism, making it both a cosmetic and therapeutic solution.
