What is PDT?
Photodynamic Therapy (PDT) is a special treatment performed with a topical photosensitizer called Levulan or Aminolevulinic Acid (ALA) and a special light to destroy abnormal cells called Actinic Keratosis (AKs).
How is PDT used?
Levulan is applied to AKs and the surrounding skin. Depending on the area and the number or the severity of the lesions, the medication will be allowed to penetrate into the skin from 1 to 4 hours. After that incubation time, a special light will be used to activate the Levulan which will cause destruction to the pre-cancerous cells.
PDT is also used for photorejuvenation and sun damaged skin. The protocols are the same as AK therapy resulting in a smooth, more even-toned complexion.
What can I expect?
After PDT, you may experience a mild sunburn feeling along with redness and possible swelling. You will be photosensitive and must avoid sunlight and bright light for 48 hours. Peeling and/or superficial crusting is usually seen during the first week and may last up to 4 weeks.
How long do the effects last?
Sometimes more than one treatment is needed to achieve desired results depending on the severity of the AKs and sun damage. Subsequent AKs may develop over time and future treatments may be needed.
PDT is a medical treatment and may be covered for the treatment of AKs by most insurance companies. PDT for photorejuvenation is considered a cosmetic procedure and
not reimbursable by insurance plans.
