The procedure starts with your dentist examining your ability to move certain muscles in your brow area and then determining where to administer the injections. The next step is administering the correct number of minuscule injections of BOTOX® directly into the muscles of your face. The procedure does not require anaesthesia and within 10 minutes, the complete BOTOX® injection procedure will be finished. There may be a minimal and brief amount of discomfort associated with a BOTOX® procedure.
