Can Botox Be Used for Face Slimming?

Botox can relax prominent masseter muscles, which would make them less visible and thus slim down your jawline. 

Botox is not able to reduce the fat component of the cheeks but if there is hypertrophy of the masseter muscles Botox can be used to decrease the mass of the muscle.by doing this the cheek slims down.

Botox can be used in a specific way to make the lower portion of the face narrower, by reducing the size of the masseter muscle. That is the muscle you can feel just above back half of the jaw when you clench your teeth. It is commonly done in Asia but less common in other regions, so you want to find an injector with specific experience. The dose is more than typically used for facial wrinbkles so it will cost a bit more.
