The Blue-U® is a very special blue light that can kill the p. acnes bactemit in your skin. Treatments are simple—you sit with your face close to the light for a short time, usually a 15 minute session, about twice per week. Treatments generally continue for five weeks. The process is very safe; it is not hot or painful at all. The Blue Light Treatment is not a laser. It emits safe, cool visible blue light to provide the desired results.
Once lesions, spots or scales are gone, skin should return to normal. You would only have to have future treatments if spots, scales or lesions re-appeared. Your dermatology provider can discuss with you how many treatments would be recommended for your condition.
