LED Light Therapy is a pain-free, non-invasive treatment that soothes and rejuvenates skin. Interestingly, different colors of light triggers different reactions beneath the epidermis and penetrates skin at varying depths. For example, blue light can kill acne causing bacteria and effectively treat blackheads and whiteheads, versus red light, which can speed up healing and stimulates collagen production, thus simultaneously shrinking enlarged pores and tightening skin. Studies have indeed shown, “red and infrared LED therapy represents and effective method of photo rejuvenation.”
