Masseter Botox helps to slim the lower face by relaxing strong jaw muscles. Ideal for clients with a square or heavy jawline, it creates a more tapered, V-shaped contour — no filler required.
Book OnlineMasseter Botox is a non-surgical treatment used to slim the lower face by relaxing the masseter muscles — the chewing muscles at the back of your jaw. For clients with a naturally strong or enlarged jaw, or those who clench and grind their teeth, this can reduce width and tension in the area. At Dr Naz Clinics, we use precise doses to soften bulk without affecting function. The result? A slimmer, more balanced facial shape — especially flattering from the front and in profile.

Masseter Botox works gradually to reduce muscle activity over time. Clients often notice both aesthetic and functional benefits — like fewer headaches or less clenching.
It’s a powerful but gentle option that doesn’t add volume or change your facial structure — it simply lets the muscle relax, leading to natural slimming. And for those who grind their teeth at night, it can bring welcome relief.
