Photodynamic (PDT) therapy for actinic keratosisThe word "photo" translates to light. “Dynamic” indicates action. Photodynamic therapy puts the two together, using specific wavelengths of light energy to combat disruption in healthy skin cells.
What to expect during photodynamic therapyTo begin treatment, we cleanse the skin to create an oil-free surface. Topical medication (Levulan) is applied, and is given 60-120 minutes to be absorbed into the skin surface. This medication causes greater sensitivity to the light. Patients recline slightly while blue light is directed towards the treatment area. Most patients experience a slight stinging sensation during the procedure but it is usually well tolerated.
After your treatmentPhotodynamic therapy may cause minimal swelling and redness for a few days. The skin may also feel somewhat tingly for a short time. During the first week following treatment, sun damaged areas may appear red and scaly. It is crucial to avoid UV exposure during the first 48 hours after photodynamic therapy. We suggest wearing titanium and zinc oxide sunscreen on a daily basis, even if it is cloudy. A hat may also be worn outside to ensure direct exposure to sunlight is reduced as much as possible.
To achieve the desired result, we may recommend a few PDT sessions. Research suggests that one to two treatments lead to improvement in 90 percent of patients. Additionally, this improvement can last several years when complimented by regular sunscreen use and healthy skin care habits.
Photodynamic therapy can clear the skin of visible actinic keratoses, as well as those that cannot yet be seen.
