What is PDT for Acne?
Photodynamic Therapy (PDT) is an effective way to treat acne. The process involves the use of a photosensitizing agent (Aminolevulinic Acid) and the application of a light source to activate the chemical. A short rest period is associated with the treatment to allow time for the medication to “incubate” on the skin.
This treatment is ideal for patients with inflammatory acne that has not responded to topical treatments or for patients who cannot tolerate or wish to be on oral medication. It does require 48 hours of sun and bright light avoidance. Several days of redness, swelling and peeling is expected followed by a much smoother, even-toned appearance of skin. Depending on the severity of acne, 2 to 3 sessions might be required at 6-week intervals.
