The PDT treatments will be done in two stages. ALA (Levulan® Kerastick™) will be applied to the entire treatment area, and then the longer light exposure (lasting up to 1 hr) will be performed on one-half of the treatment area (Side A). After that, a shorter (16 min 40 sec) light exposure will be done on the other half (Side B).
