Photodynamic Therapy (PDT) is a convenient in-office treatment that targets and destroys precancerous cells known as actinic keratoses (AKs) on various areas of the body. By treating sun-damaged skin more broadly, PDT can help reduce the need for frequent freezing treatments and biopsies during routine skin checks. Most insurance plans, including Medicare, commonly cover this therapy, and our office performs a benefits verification prior to scheduling to review your specific coverage details.

We offer Photodynamic at our Columbia location. If you or your referring provider is interested in scheduling a consultation or treatment, please complete our online request form, and a member of our team will be happy to assist you!

How does PDT work

  1. Application of a photosensitizing topical (aminolevulinic acid) is applied to the treatment area. Curettage may be performed on visible sun-damaged skin to maximize absorption.
  2. Incubation period, time dependent on treatment area, allows for the photosensitizing agent to be absorbed primarily by rapidly dividing, precancerous cells.
  3. Blue light (417 m) on the skin for approximately 17 minutes. This light activates the photosensitizing agent, producing reactive oxygen species that damage and destroy the precancerous cells. Healthy, normal skin cells are largely unaffected by this treatment.

What is the recovery process like?

Expect the treatment area to likely feel similar to a sunburn and may appear red and sensitive. Redness, peeling, and flaking are common and expected parts of the healing process. Blistering is very rare. The intensity of the skin reaction is generally proportional to the degree of underlying sun damage.

Patients should strictly avoid sunlight (both direct and indirect exposure) for 3 days post-treatment. Sun protective measures are essential and include wearing broad-spectrum sunscreen, protective clothing and hats, and avoiding peak sun hours.

Healing is typically complete within 10-14 days, depending on the area treated (healing may take longer on the legs).
