uses light-activated aminolevulinic acid to treat skin conditions
ALA-PDT, or Aminolevulinic Acid Photodynamic Therapy, is a medical treatment that uses a photosensitizing agent called aminolevulinic acid (ALA) combined with light exposure to target and destroy abnormal cells. This therapy is commonly used for treating certain skin conditions, including actinic keratosis and some types of skin cancer, by applying ALA to the affected area and then activating it with a specific wavelength of light, leading to the selective destruction of the abnormal cells.
