Photodynamic Therapy

Photodynamic therapy (PDT) combines a topical drug, called a photosensitizer, with a special light source to treat a variety of skin disorders and has recently emerged as an effective treatment for aging skin. Photodynamic therapy may be recommended to treat actinic keratoses (precancerous skin growths on sun-damaged areas), as well as moderate-to-severe acne, wrinkles, visible blood vessels, rosacea, certain cancers, including skin cancer, enlarged sebaceous glands, and psoriasis.
