Will Botox & jaw reduction make my upper cheeks look more prominent? I'm now 39 and had botox jaw reduction 18 months ago.

I have been injecting Botox for aesthetic purposes for twenty years and for masseter (lower jaw) reduction for nearly a decade, particularly in patients of Asian decent. In that time, I have not seen (nor have even read about) any secondary beneficial effects of this technique in enhancing or augmenting the cheeks.However, we are now fortunate to have two wonderful injectable volumizing agents, Radiesse and Voluma XC, that work well for nonsurgical cheek augmentation and typically achieve in about ten minutes gratifying results that last for approximately two years. I routinely use the latter two agents for creating higher cheekbones and improving light reflection and projection in my Upper East Side Manhattan office. In my Israel satellite facility, where a far greater number of regulatory agency approved fillers and volumizers are available, I prefer Emervel Volume and Stylage XXL for these purposes).

Masseter injections have no effect on the cheeks.  I do this treatment daily for many years now and have never seen a change in the masseter effect the cheeks.  Best, Dr. Emer.

chewing is done by the masseter muscle and the temporalis muscle.  "upper cheek" muscles do not replace the masseter.
