What is Masseter Botox (Jaw Reduction Botox)?

Masseter Botox, also called jaw reduction Botox, is a non-surgical treatment that reduces the size of the jaw muscles by injecting botulinum toxin (Botox) into the masseter muscles. Overactive or enlarged jaw muscles can cause a square or bulky jawline. By relaxing these muscles, the jawline becomes slimmer and more contoured, resulting in a softer and more feminine or V-shaped appearance. The procedure is quick, minimally invasive, and requires no downtime compared to surgical jaw reduction.

Ideal candidates are individuals with a wide or square jawline caused by enlarged masseter muscles. It is also suitable for those who grind their teeth (bruxism) or clench their jaw excessively. Patients should prefer a non-surgical approach, be in good health, and have realistic expectations regarding gradual results that improve over several weeks.
