What is Photodynamic Therapy?

Photodynamic Therapy (PDT) is an FDA-approved treatment for actinic keratoses (AKs) or precancerous lesions. Although primarily used for precancerous lesion treatment, it can be effective for treatment of early superficial skin cancers as well.

Photodynamic Therapy Procedure

Photodynamic Therapy (PDT) is completed in a 2-stage process. Stage 1 includes topical application of a photosynthesizing agent that makes the skin extremely sensitive to light. Stage 2, which takes place 14 to 18 hours after the medicine is applied and includes a 20 minute session exposing the area being treated to a BLU-U Blue Light. After stage 1 - avoid exposure to sunlight or bright indoor light.

After the procedure is complete, protect treated area from the sun by wearing a wide-brimmed hat or head covering. Sunscreen will not help protect against a photosensitive reaction. Side effects may include redness, swelling, and crusting which may last up to 4 weeks. You may begin reapplying makeup after crusting resolves.
