Photodynamic Therapy for Acne: Use of the Pulsed Dye Laser and Methylaminolevulinate

Recent decades have seen the inclusion of acne vulgaris as a potential new indication for photodynamic therapy. Photodynamic therapy and light sources can be considered to be additional tools for primary or adjunctive therapy in patients with recurrent acne or those in whom it is not possible to use other treatments. We investigated the use of pulsed dye laser plus methylaminolevulinate for photodynamic therapy and have performed a comparative study of the use of this laser alone and as an element in photodynamic therapy.
