One session lasts three to four months. The neck moves constantly with speech and head turning, so the same dose tends to wear off a little sooner than on the face. Keeping the result means repeating, and people with thicker vertical bands often need a shorter interval.

Rarely, swallowing can feel odd. The drug is placed shallowly and in divided amounts along the front-neck band so it does not spread to the swallowing muscles, so most people have no issue, and when it happens it clears in a few days. Staying upright for four hours after helps keep the drug from migrating.

The vertical cords soften over about two weeks. The bands only settle once the muscle loses its pull, so nothing changes overnight. Horizontal creases come from thinning skin rather than muscle, so they respond poorly to this and are approached separately with skin filler.
