Detailed informed consent will be obtained prior to treatment at study enrollment. The first four treatment visits will involve clinical evaluation, photography and application of the ALA to the affected area. After a 45 minute incubation period, the area will be washed and then treated with either blue light or intense pulsed light (IPL), depending on body area/investigator choice. One and three-month follow-up visits will involve evaluation of efficacy, but no active treatment.
