Photodynamic therapy (PDT) is a minimally invasive procedure used to treat precancerous lesions (Actinic Keratoses), skin cancer and other conditions such as acne. PDT uses a topical photo sensitizer called Levulan, along with a light energy source to destroy abnormal skin cells. The Levulan is applied to the skin and incubated for a certain amount of time before it is exposed to light energy to activate the medication and destroy the targeted cells.
Many people see successful results from PDT after one treatment session, but periodic treatments are usually required to maintain clear skin. This procedure may be combined with other treatments in order to maximize results and leave skin as healthy and beautiful as possible.
