Blue light is probably the best-known light therapy for acne treatment. Dermatologists have been using Acne Blue Light Treatment to minimize and eliminate outbreaks for over two decades.The FDA approved blue light therapy for treating acne in August 2002.
In contrast to other treatments, patients do not have to apply a cream to their skin and it's free from side effects. The technique simply relies on the interaction of the blue light with the infected skin. Blue light acne treatment is a non-invasive treatment that uses light in the blue wavelength range of 405-420 nm to kill the Propionobacterium acnes or P. acnes bacteria in skin.

The healing quality of light has been understood for centuries. The power of red LED light energy activates the body's own natural rejuvenation processes to counteract the signs of aging by activating local cellular metabolism, promoting circulation and stimulating the skin's fibroblasts which leads to a natural increase in collagen and elastin production. Many studies have shown that the cellular and metabolic effects of Facial Light Therapy can improve skin tone & texture, help to refine fine lines and wrinkles, reduce redness and inflammation and promote brighter, smoother, more youthful-looking skin.
