What is masseter Botox and does it slim the jawline?

Masseter Botox is a botulinum toxin treatment applied to the chewing muscle (masseter). It is highly effective for treating bruxism (teeth grinding) and slimming the facial contour. An overdeveloped masseter muscle gives the face a square appearance; Botox reduces this muscle, allowing the facial line to become oval and refined. Effects become visible within 2-4 weeks and last 4-6 months. It also provides significant relief from jaw pain and headaches.
