Photodynamic therapy is a non-invasive medical method of treating common skin conditions such as acne, psoriasis, age spots, sun damage, wrinkles and rosacea. A photosensitizing chemical substance is used on the patients affected area, when combined with the light source those specific cells are targeted. Photodynamic therapy is also used to treat and help eliminate pre-cancerous cells (actinic keratosis).
PDT usually results in great cosmetic outcomes, and is less painful and intrusive as other forms of treatment.
Present in natural sunlight, ultraviolet B (UVB) is an effective treatment for psoriasis. UVB penetrates the skin and slows the growth of affected skin cells. Treatment involves exposing the skin to an artificial UVB light source for a set length of time on a regular schedule.
