The masseter is the main chewing muscle, running from the cheekbone to the angle of the jaw. When it is overworked — clenching through the day or grinding at night — it tightens and aches, can set off headaches and facial pain, and over time bulks up enough to square off the lower face.
A series of small injections into each masseter relaxes the muscle temporarily. Less clenching and grinding means less jaw pain and fewer tension headaches, and as the muscle softens the jawline tapers for a slimmer, more V-shaped lower face.
Results settle in over six to eight weeks. Regular treatments maintain the result and can prolong it over time, refining the jawline further.
Masseter treatment is priced per unit like all Botox. The number of units is set at consultation, and the 30-unit appointment minimum applies.
