BLU-U^®

Photodynamic Therapy with BLU-U^® used to treat acne, pre-malignant actinic keratoses, and is useful in facial rejuvenation

Photodynamic therapy, PDT, uses a photosensitizing agent, delta aminolevulinic acid HCL, and a visible light source to treat pre-malignant lesions, acne, and rejuvenate the skin. The delta aminolevulinic acid is absorbed by the upper layer of skin and is broken down to protopohryin IX, a very potent photosensitizer. A light subsequently delivered to the treatment area releases free oxygen radicals that damage cells. This mechanism of action can help reverse pre-malignant changes. It also kills the P. acnes, the primary bacteria responsible for acne.

The area to be treated is cleansed and the photosensitizing agent applied. Approximately one hour later, it is washed off and the area is exposed to the BLU-U® or a yellow light for a specific amount of time. Light exposure is generally between 10 and 16 minutes and may be associated with a mild stinging sensation. A sunscreen is applied prior to leaving the office. However, the patient must remain indoors and avoid strong halogen, fluorescent, and visible (outdoor) light for 36-48 hours because available sunscreens do not protect against visible light. Visible light can cause a severe burn. Some redness and mild swelling are normal after treatment and subside with a couple of days.

The average patient requires between 3-4 treatments, but this may vary depending on the type and severity of the skin condition.
