How Does Masseter Botox Work?

Jaw clenching and a square jawline are often caused by hypertrophy of the masseter muscles. When injected into the masseter, Botox relaxes the muscle → reduces clenching and tension → gradually slims the jawline → maintains natural chewing and expression.

Treatment Dosage Guidelines

17.5–20 units

Female patients

20–30 units

Male patients (greater muscle strength)

Dosage is individualized based on muscle activity, jaw shape, and treatment goals. Dr. Fuzayloff carefully adjusts the dose to achieve balance while preserving natural function.

What to Expect During & After Treatment

Consultation

Dr. Fuzayloff evaluates your jaw muscles, facial structure, and concerns such as clenching, teeth grinding, or jawline width.

Treatment

Several small Botox injections are placed directly into the bulk of the masseter on each side of the jaw. Injections are carefully distributed to ensure balanced relaxation.

Aftercare

You may notice mild swelling, redness, or tenderness, which usually resolves quickly. Normal activities can be resumed the same day.
