Will masseters keep shrinking with repeated Botox? How can I maintain the effect without further slimming?

Hello Ginger_Snap123! My name is Jessica, I am a physician assistant, and one of the providers at Shah Facial Plastics. Thank you for your question. In general, patients who receive Botox treatment for TMJ related pain need 2-3 treatments followed by maintenance treatments every 6-12 months depending on the results. Further, based on your results, in order to balance the slimming effect and reduce pain, its important to properly dose the Botox during each treatment. I recommend scheduling an appointment for an in-person consultation to better assess your face. I hope this helps and best of luck!
