Is a masseter botox treatment suitable for treating chubby cheeks in men?

Thank you for your question. If your masseter is responsible for the increased volume in your cheeks, then injecting Botox into this area will slim your face. However, there are other causes of chubby cheeks and a man-shape of the jaw and underlying adipose tissue that can be addressed with skin tightening procedures or dermal fillers.. I recommend you schedule an appointment with a board-certified cosmetic dermatologist who can perform a comprehensive examination and listen to your concerns and goals in detail. From that meeting you should be able to create a customized treatment plan that meets your expectations. Good luck to you!

Botox injections to the masseter muscle can reduce the volume of cheek musculature but if a patient has "chubby cheeks" due to fatty deposits in the buccal mucosa this is often treated with buccal fat removal directly.  It may be best to discuss this in a 1-1 consultation with the surgeon to be sure what procedure is best suitable for you. Be sure to trust your face to a specialist and best of luck to you.

Occasionally, yes but each case is best determined by a consult with a professional.   Botox is useful for enlarged, tight cheeks if you  have TMJ but it is not useful if a person simply has excessive adipose (fat) tissue on their cheeks.  This is best remedied with surgery.
