A consultation with a dermatologist-trained SOM provider is required to confirm candidacy, dose plan, and safety. Precise placement helps protect smile and chewing function.
Masseter Botox uses precise neuromodulator placement in the masseter muscle, which contributes to jaw clenching and grinding. Reduced muscle activity may soften a square jawline and may support some patients with TMJ-related tension.
Masseter Botox is non-surgical and temporary. It is not a diagnosis or cure for TMJ disorders, and candidacy depends on symptoms, anatomy, medical history, and a clinical assessment.

At SOM, dosing is mapped to your facial movement, asymmetry, and goals, not a generic chart. The result: softer lines that still let your face be your face. Over 3–4 months, Botox gradually metabolizes and muscle function returns.
• Stop blood-thinning supplements 48h prior
• No alcohol 24h before
• Clean skin, no makeup on the jaw
• Mention any jaw, TMJ, or dental changes
• Plan a relaxed 24h after

The appointment typically takes 10–15 minutes. A dermatologist-trained SOM provider maps the masseter muscles and places precise injections based on anatomy and the treatment plan.
• 10 to 15 minute appointment
• A few precise injections per side
• Mild pinch, no numbing needed
• No downtime, walk in and out

Avoid rubbing or massaging the area for 24 hours, stay upright for about 4 hours, and skip strenuous exercise that day. Jawline slimming develops gradually over 6 to 8 weeks as the muscle relaxes. Results typically last 3 to 4 months.
• Stop blood-thinning supplements 48h prior
• No alcohol 24h before

SOM providers may combine masseter Botox with other treatments when a balanced lower-face plan is appropriate.

Platysmal bands, laxity, texture, and contour planning for the neck and décolletage.

Masseter Botox relaxes the chewing muscle before the face looks slimmer. Jaw tension may begin to ease within 2 to 3 weeks, while visible jawline slimming usually develops over 4 to 8 weeks and may continue through 10 to 12 weeks. Timing varies with muscle size, dose, and individual response.
Temporary chewing fatigue or an uneven smile can occur if treatment affects nearby muscles. Careful mapping and conservative dosing help reduce this risk. Contact SOM if you notice unexpected weakness, asymmetry, difficulty chewing, or another change in normal function.
Masseter Botox may reduce chewing-muscle overactivity in selected patients and can lessen jaw tension or clenching. It does not treat every cause of TMJ symptoms and does not replace dental or medical evaluation. A dermatologist-trained SOM provider reviews your symptoms and history before recommending treatment.
Effects often last about 4 to 6 months, but the interval varies with muscle activity, dose, and whether the goal is jawline slimming, clenching relief, or both. SOM reassesses jaw function, symmetry, and facial balance before repeating treatment instead of using an automatic schedule.
Botox cannot be dissolved, but its effect is temporary and gradually wears off as muscle activity returns. Conservative dosing and clear goals help reduce the risk of over-slimming or imbalance. Contact SOM if the result feels uneven or affects normal function so the area can be evaluated.
Cosmetic jawline slimming is generally self-pay. Any insurance coverage for medically diagnosed symptoms depends on the plan and is not guaranteed. SOM confirms provider-neutral pricing after evaluating muscle strength, symmetry, and treatment goals.
