How is PDT performed?
PDT is a new therapy and there are currently different methods in use. For example, physicians may use blue light, red light, or intense pulse light. The photosensitizer is applied to the skin, and is left on for a variable period of time. The skin is then exposed to the light source and the photosensitizer is then removed. Reported side effects include transient burning, stinging, swelling, and redness.
