The schedule

One session, then a wait of three to four months. The injector maps your muscles while you frown, lift and squint, because every face pulls differently, and the points follow your anatomy rather than a template. Facial sessions typically land three times a year; masseter shaping can hold six to twelve months from a single session, so it often needs only one or two a year. For migraine the pattern is fixed, across seven muscle groups of the head and neck, repeated about every twelve weeks.
