Will jaw muscles start to feel weaker after Botox?

Thanks for your question and yes, as a rare effect, one might notice this after Botox but most of the time this is nothing major and nothing that should be worrisome for you.  Botox effects are not permanent so if it does occur, it will resolve over time.

Thank you for your question clairexx12. Botox is a purified protein used to address wrinkles associated with
facial expression. Botox can be placed in the masseter muscle to contour the lower face. Botox will relax this muscle that is used for biting. Depending on the dose, chewing may be more difficult. Please consult with a doctor for specific recommendations. Good luck!
