Photodynamic therapy is a relatively new and rapidly evolving therapeutic option in dermatology. Initially used for the treatment of actinic damage and nonmelanotic skin cancer, more recent work indicates efficacy in the treatment of a wide range of conditions, such as acne, infectious processes, cutaneous T-cell lymphoma, and photorejuvenation, among others. This article provides a comprehensive review of applications and outcomes that use topical photodynamic therapy in the treatment of dermatologic disease.

ALA-PDT is a safe, well-tolerated, and effective treatment for many dermatologic conditions. Current data most strongly support its use in the treatment of actinic damage, but further investigation into alternative uses continues. Current efficacy is limited primarily by the depth of penetration of the photosensitizing agent and the activating light source. Even with this limitation, the potential applications of PDT are numerous. As new technology is developed to overcome current restraints, the future of PDT is wide open.
