Botox side effects
Thank you for your question ali_alicia07. I am sorry to hear about your situation. Botox is a purified protein used to address wrinkles associated with facial expressions. In the lower face Botox can be placed in the masseter to contour the face. Any time Botox is placed in the skin there is a possibility of spreading of the Botox. If Botox spreads to nearby muscles, these muscles can be relaxed. Nearby the masster are the zycomaticus muscles which are used for smiling. If these muscles are relaxed smiling may be affected. Typically Botox lasts 3-4 months but with higher doses it can last longer. Please follow up with your doctor for specific recommendations. Good luck!
