Abstract
With the advent of short contact and pulsed light techniques, topical 5-aminolevulinic acid photodynamic therapy (5-ALA PDT) has become a viable clinical modality. Intense pulsed light, the pulsed dye laser, and blue light-emitting lamps have become the most commonly used devices in inducing a cosmetic PDT effect. More recently, by combining the photothermal effects of pulsed light with the photochemical effects of PDT, an enhanced cosmetic effect has been demonstrated in a variety of dermatologic conditions. In addition, the use of shorter 5-ALA incubation times allows for improved patient tolerance during treatment and subsequently fewer adverse effects in the postoperative period. A review of the current literature on cosmetic uses of PDT as well as our personal techniques are discussed in detail.
