Topical photodynamic therapy, also known as PDT, is a treatment that has been used in dermatology for about 30 years. Photodynamic therapy is a treatment that utilizes a topical product to photo-sensitize specific areas of the skin to enhance the effects of light therapy. The treatment is most commonly used in dermatology for actinic keratosis and non-melanoma skin cancers for which it is FDA-approved. Dermatologists have evaluated its off-label use for the treatment of acne vulgaris, rosacea, sebaceous hyperplasia, and hidradenitis suppurativa. During research into the use of photodynamic therapy in the treatment of facial actinic keratosis, researchers noticed marked improvements in visible signs of aging such as fine lines, dyspigmentation, and texture. There is now a cosmetic form of photodynamic therapy available to aestheticians that improves the overall appearance of the skin. Cosmetic photodynamic therapy improves the appearance of fine lines and wrinkles, pore size, skin laxity, texture, and tone.
