Developed as a treatment for actinic keratosis (AK), PDT (photodynamic therapy) also may provide the patient significant aesthetic enhancements.
Photodynamic Therapy combines a topical drug (called a photosensitizer) that is preferentially absorbed by certain kinds of cells and a light source. When used together the photosensitizer and the light destroy undesired lesions. When PDT is used for rejuvenation of the skin aminulevulinic acid, a clear solution is applied to the entire surface of the skin to be treated. After an appropriate amount of time, the skin is exposed to a light or laser source.
After the treatment the skin is extremely light sensitive for 48-72 hours. Light exposure is to be avoided to protect the skin during this time. Most of the time, redness and mild peeling occur over the next 2-3 days. Occasionally, there can be a burning discomfort for 24 hours and prolonged peeling and redness of up to 5-14 days can occur. Gentle skin care should be used for 48 hours post treatment. Do not use AHA or any abrasive products for 48 to 72 hours after PDT treatment. Sessions are generally 2 to 3 weeks apart and 1 to 3 treatments are advised.
