Photodynamic Therapy (PDT) is an effective procedure used to treat pre-cancers called actinic keratosis (AK). The treatment combines the application of a topical solution called Levulan® Kerastick®. When absorbed by the skin, it will become activated by the blue light source to destroy damaged cells. PDT has a high success rate with good preservation of normal skin with little chance for scarring. PDT allows for an entire area of sun damaged skin to be treated at once, thereby reducing the chance of undetected pre-cancer cells going untreated.
PDT has three steps:
Immediately following the PDT treatment you may experience the following common symptoms of redness, scaling and slight swelling which may become increase during the next 24-48 hours. Itching and mild to moderate pain may occur.
Flakiness, crusting and rarely blistering may occur during days 2-7 following treatment and is best referred to as an intense sunburn-like reaction.
Generally days 7-10 you will notice the redness and scaling have subsided therefore the healing process has already begun.
