ABSTRACT
Enhancement of pulsed light sources and visible wavelength lasers can be performed with short contact photodynamic therapy. Topical 5-amino levulanic acid is applied for 60 to 90 min before treatment with pulsed light or pulsed dye laser treatment. Enhancement of photorejuvenation ( 5 ) with a variety of light sources has been reported, requiring fewer treatments and also leading to a greater “resurfacing” effect ( Fig. 30.1 ). Another photosensitizer, Metvix (MAL) is also being investigated for this application.
