Photodynamic Therapy (PDT)
Photodynamic Therapy (PDT) helps to eliminate actinic keratoses and improve sun-damaged skin via a photochemical reaction between aminolevulinic acid (ALA) and a visible blue light source.
In this therapy, first the photosensitizing chemical is placed on the skin.
After the ALA has had a chance to penetrate the skin cells either the face or scalp (depending upon the area being treated) are exposed to the BLU-U light. Only damaged cells are affected. The treatment is usually tolerated well, though it may sting a bit. For 48 hours after treatment you must stay out of the sun and protect yourself completely from additional sun exposure in order to avoid a serious sun-burn type reaction as the ALA remains active in the skin during this time.
PDT can greatly decrease the need for other therapies to treat actinic keratoses. This procedure is typically covered by insurance carriers, including Medicare.
