Photodynamic Therapy is a light treatment performed with a topical photosensitizing agent called Levulan (aminolevulinic acid). This therapy is used to treat pre-cancerous lesions called actinic keratosis, sun damage, and pigmentation from sun damage. It is also used to reduce oil production from oil glands which help with acne breakouts. Most people obtain good results with one to three treatments but may require more treatments to obtain desired results.
