Botox can be used to slim and contour the face by targeting the masseter muscles at the back of the jaw. These muscles can give the face a more square appearance due to their size and shape. Botox works as a muscle relaxant and can help patients sculpt a slimmer jawline by relaxing the masseter muscle and making it appear less prominent. This creates an oval-shaped face for patients while relieving jaw tension in the treatment area. The result is a reduction in the size of the muscle over time, leading to a slimming of the facial and jaw area. Jawline slimming with Botox utilizes strategic injections into the posterior muscles of the jaw (masseter muscle) to gradually reduce the jaw muscle size over time. Botox injections can also be used in the masseter to relieve symptoms of TMJ, such as jaw pain, headaches, TMJ damage, and poor range of motion in the jaw. Overall, Botox can help slim and contour the jawline by reducing the size and prominence of the masseter muscles, leading to a more oval-shaped face and relief from jaw tension and TMJ symptoms.
