Light Therapy is a non-invasive treatment to treat sun damaged skin and acne. This treatment utilizes a photosensitizing molecule (frequently a drug that becomes activated by light exposure) and a light source to activate the administered drug. It helps in shrinking or destroy the sebaceous (oil) glands that cause acne and it also helps the skin retain moisture, and distributes antioxidants, hormones, and pheromones over the skin.
