PHOTODYNAMIC THERAPY IS LIGHTING THE WAY FOR MEDICAL AND COSMETIC TREATMENTS

March 3, 2006

For the millions of people who suffer from acne, sun damage or even worse, skin cancer, there is a light of hope - photodynamic therapy or PDT. Originally approved by the U.S. Food and Drug Administration (FDA) to treat cancer, dermatologists initially focused on using PDT to treat actinic keratoses (AKs), the earliest stages in the development of skin cancer. As PDT treatments became refined, the therapy expanded to provide patients with a safe, non-invasive treatment option for acne, sun damage and potentially basal and squamous cell carcinomas, the two most common forms of cancer in the world.
