Botox for V shaped face?

I love botox for this area.  I suggest an expert as if this is done improperly it can cause chewing and smiling issues.  Best, Dr. Emer.

Botox for masseter reduction will certainly reduce the fullness along the angles of your mandible - where the masseter muscle attaches to your jaw.  A typical starting dose for Botox is 25 units on each side.  The most significant slimming effect will be experienced in the first month, and will continue for 3-4 months while the Botox is active.  

Botox can be injected into the masseter muscle.  This is the muscle that clenches the jaw shut.  Over many treatments, the muscle can atrophy, making the face look slimmer.  Botox however, doesn't slim down "chubby cheeks."  Good Luck.
