Photodynamic Therapy (PDT) is the process of using a topical medication called LevulinTM (aminolevulinic acid) and activating this medication with a light source (usually blue light). PDT has been used successfully for treatment of many skin problems. Probably the best usage has been to treat acne, aging spots called seborrheic keratosis, and precancerous skin lesions called actinic keratosis. Additionally, PDT has been studied and successfully used for many other medical uses.
At Laser Away, we have used PDT for a variety of medical treatments but by far we have used it most for acne treatments and skin blemishes. LevulinTM is a photo-sensitizing medication that has the unique ability to reduce pores and glands, thus improving acne.
At Laser Away, this treatment is a 3-step process. First, we gently cleanse your skin using microdermabrasion to remove the dead skin on the skin’s surface. Next, we apply the topical medication Levulan over the face (or other areas to be treated). The LevulinTM is left on the skin for 60 minutes (called the incubation time). Lastly, the LevulinTM is “activated” using the Blu-U light for a short time (8-12 minutes).
The treatment is usually painless. However, sometimes people will report a stinging sensation during the activation of the LevulinTM. Afterwards you must stay out of the sunlight for 48 hours. Treatments can be repeated in 2-4 weeks if they are needed. Usually 1 - 3 treatments are needed.
