Photodynamic Therapy: Treatment For Acne and Actinic Keratosis

Most adults know that skin problems don’t disappear once your teenage years are over. Certain conditions such as acne can persist well into adulthood, while other skin issues develop with age. Fortunately, photodynamic therapy (PDT) is a treatment that effectively controls a number of skin conditions, including actinic keratosis and moderate adult acne.

Photodynamic Therapy For Actinic Keratosis

Actinic keratosis is a pre-cancerous skin condition which form as a result of prolonged exposure to ultraviolet rays, usually from the sun or tanning beds. Sun-damaged skin affected by actinic keratosis appears as a dark, rough, scaly patch. If left untreated, it may turn into squamous cell carcinoma, a type of skin cancer.

PDT is a treatment that uses light to destroy the abnormal skin cells that cause actinic keratosis. The procedure is performed in three steps, starting with the application of a topical photo sensitizer, which is left on the skin for a period of several minutes, or up to several days. This is known as the incubation period. After the incubation period, the photo sensitizer is activated by the wavelengths of a light source. During this time, patients may feel a tingling or warm sensation. The area is then washed, and patients are free to go home. Most patients return to work a day or two following treatment. Depending on the severity of the condition, multiple sessions may be required to achieve optimal results.

Blue Light Therapy For Acne

BLU-U® Blue Light Photodynamic Therapy is a non-invasive treatment that controls moderate acne without drugs or antibiotics. This procedure uses advanced blue light technology to kill the bacteria that causes acne, while still being gentle on the skin.

During treatment, patients sit with their faces close to the blue light for a short period of time–usually a few minutes, once or twice per week. A typical session lasts about 16 minutes, however the length of time spent in front of the light and the number of therapy sessions depend on the severity of the acne.
