Photodynamic Therapy

Treatment for acne, sun damage and more

Photodynamic therapy (PDT) is a procedure that uses a photosensitizing drug (Levulan Kerastick™ – aminolevulinic acid HCl) to apply light therapy selectively to target precancerous lesions, acne and sun damage.

PDT can help clear actinic keratoses which are common premalignant lesions found in sun-exposed areas. It is also very effective for moderate to severe acne. A series of treatments of PDT alternating with blue light alone can put acne into remission for months and even help with scarring. PDT can also help improve the appearance of sun-damaged skin over time.

It is important to note that PDT makes the skin sensitive to sunlight for 48 hours after treatment. For patients with extensive actinic keratoses, significant redness and peeling can occur after treatment and last for up to a week.
