Photodynamic
Therapy (PDT) is a non-invasive dermatologic treatment that uses a
photosensitizing agent activated by a specific light source to destroy abnormal
or damaged skin cells. It is commonly used to treat actinic keratoses and early-stage superficial skin cancers.
The treatment works by applying a topical
medication—typically aminolevulinic acid (ALA)—which is absorbed by targeted
cells. After a period of incubation, the treated area is exposed to a
specialized blue or red light, which activates the medication. This process
creates a reaction that destroys the problematic cells while preserving
surrounding healthy skin. PDT can be applied to the face, scalp, chest, and
extremities, depending on the condition being treated.
At our office, we offer non-invasive treatment options using the BLU-U Blue Light Photodynamic Therapy Illuminator. When combined with Levulan Kerastick (aminolevulinic acid HCl) 20% Topical Solution, the BLU-U is effective for treating minimally to moderately thick actinic keratoses on the face or scalp.
Treatment
begins with a thorough skin evaluation to determine whether PDT is appropriate
for the patient’s condition and skin type. During the procedure, our experienced providers will first apply a photosensitizing agent to your skin, which is then activated by a specific wavelength of light to target problem areas while protecting healthy tissue. This minimally invasive procedure is designed to reduce the risk of scarring compared to other treatments. Our team will monitor your progress and ensure optimal results.
The procedure
typically takes 30–60 minutes and may cause temporary redness, burning, or
peeling—similar to a sunburn. Most patients return to normal activity within
24–48 hours but must avoid sunlight for at least 48 hours post-treatment to
prevent additional photosensitivity. Multiple sessions may be needed depending
on severity and treatment goals.
