BotoxCalcBotox Cost — Masseter / Jaw Slimming
Answer first: Masseter Botox for jaw slimming typically uses 40–60 units total across both sides — about $520–$780 at a typical $13 per unit. It is the highest-unit cosmetic area on this site because the masseter is a large, strong muscle.

Jaw slimming vs TMJ — an important distinction
Answer first: Masseter treatment for cosmetic jaw slimming typically uses 40–60 units total across both sides (about $520–$780 at $13 per unit). Masseter injections are also discussed in the context of teeth grinding and jaw tension (often grouped under TMJ/TMD discussions), but BotoxCalc makes no treatment claims for any medical condition: whether masseter treatment is appropriate for a medical concern is a question for a licensed medical or dental professional after diagnosis, and coverage and dosing differ from cosmetic use.
Masseter muscles are large and strong compared with upper-face muscles, which is why unit counts — and therefore cost — are higher, and why results are usually assessed over weeks as the muscle gradually reduces in bulk. Chewing function and facial anatomy must be assessed in person before any treatment.
