Masseter Neuromodulator & Facial Slimming in San Francisco
Masseter treatment can change muscle activity and, over time, lower-face contour in selected patients. THCB evaluates facial width, asymmetry, clenching history and broader lower-face proportions before treatment planning.
Lower-face width has more than one cause
A broad or square lower face may reflect masseter hypertrophy, skeletal structure, soft tissue, parotid prominence, jawline shape or a combination. Neuromodulator treatment only addresses the muscle component, which makes proper assessment important before promising a slimming effect.
Aesthetic goals and jaw symptoms should be separated
Some patients are primarily interested in facial contour; others also report clenching or jaw discomfort. Those are not identical treatment objectives, and patients with significant pain or functional symptoms may need appropriate dental or medical evaluation rather than treating an aesthetic injection as a complete diagnosis or solution.
Compare resting and clenched masseter prominence.
Assess side-to-side asymmetry.
Clarify aesthetic slimming versus symptom-related goals.
Consider chin and jawline structure before combining filler and neuromodulator treatment.

Frequently asked questions
Does masseter Botox make every face slimmer?
No. It can only influence the muscle component of lower-face width, so anatomy and baseline masseter prominence matter.
Is it the same as TMJ treatment?
Patients may have overlapping clenching or jaw symptoms, but aesthetic masseter treatment should not be presented as a complete evaluation or treatment for every temporomandibular disorder.
How long does facial slimming take?
Visible contour change can be more gradual than the initial change in muscle activity and varies by individual.
Can it be combined with chin or jawline filler?
Combination planning may be appropriate in selected patients, but each modality should address a defined anatomical goal.
