This amazing hand-held device delivers blue light therapy that improves acne-prone skin with its purifying and antibacterial properties. Blue light is absorbed by the bacteria that produce the inflammation associated with acne, ultimately destroying them. With the elimination of the bacteria, acne starts to clear. According to findings of the American Academy of Dermatology, exposure to blue light for 15 minutes twice a week, for 4 weeks, has produced a 60% reduction of acne on 80% of patients.Light therapy is safe, non-invasive, and requires no post-treatment down time.
