Botox to Contour Jawline?

Botox for the masseter achieves temporary results that last a few months. The exact dosing for your masseter reduction can be determined in consultation with your cosmetic physician, as it is important to see how strong your muscles are with an in-person evaluation. However, to give you an idea, you may require approximately 30 units of Botox per side. Multiply 30 with the average cost of a Botox unit, which would range from $300-$400.

There is not a standard dose of botox (# of units ) for treating a masseter muscle for hypertrophy.  Most patients require around 25 units per side with considerable amount of variation based on size of masster muscle itself.  

The amount of Botox into the masseuse muscle depends on how bulky the muscle is. 20-50 units per side is possible. Make sure you are properly examined by a physician who has experience with massager injections.
