The muscles in the forehead, such as the procerus and corrugator supercilli, often respond well to a few units of the medically prepared toxins, administered by shallow injection, and the 'relaxation' of such muscles can reduce the recipients ability to frown; thereby often giving a 'smoothing effect' to the area over its duration of action.
If they respond positively, then the corrugator supercilli muscle is removed during a small operation, which takes about 45 minutes.
Treatment usually begins with 10 MU into each corrugator supercilli and can be repeated as necessary.
