Photodynamic Therapy

PDT destroys abnormal cells by harnessing the power of a topical photo sensitizer called Levulan, or aminolevulinic acid (ALA), combined with a special light and molecular oxygen. ALA, a natural substance found throughout the body, is activated by light to destroy target tissue cells.

The dermatological community regards PDT as an effective method for treating actinic keratoses (AK’s) and Bowen's disease, leaving you with clearer skin that also shows improvement of fine lines and blotchy pigment.

PDT also has the power to minimize pores, reduce oil production, and kill acne causing bacteria, effectively treating stubborn acne vulgaris, acne rosacea, and even the appearance of acne scars. Better yet, PDT acts not only to decrease active acne breakouts but also to reduce pore size, helping to prevent future acne by minimizing the breeding ground available to bacteria.

For acne-related PDT treatment, you can expect to be in our office for about 30 minutes. Prior to the procedure, your skin will be prepped, ensuring skin is clean and free of all makeup, moisturizers, and sunscreens. The PDT protocol for acne involves sitting under the Blu-U light source with goggles on for an 18-minute session.

If you are getting PDT treatment for sun-damaged skin and/or precancerous lesions, your appointment will last approximately 90 minutes. Your skin will be prepped, ensuring skin is clean and free of all makeup, moisturizers, and sunscreens. Topical ALA will then be applied to your skin and will be allowed to incubate for approximately 1 hour. The protocol for AKs involves sitting under the light for 22 minutes.

You may feel a very mild stinging when your skin is exposed to the light. After the session is complete, you should feel no pain. You can expect mild to moderate redness and scaling that may persist for up to 5 days, similar to a mild sunburn.

Patients usually require at least 3 treatments spaced at 3 week intervals, with maintenance sessions recommended to achieve long term reduction in lesions.
