low level light therapy with infrared light has been shown to be effective for the treatment of acne and other sorts of skin lesions. There have been some really nice studies actually where they use subjects as their own internal control. So people, believe it or not, agreed to have half of their face illuminated with red light or near-infrared light, and the other half of their face serve as a control, and to do that for several weeks at a time. And you can see pretty impressive reductions in skin lesions, reductions in scars from acne, and reduction in acne lesions themselves, meaning the accumulation of new acne cysts with low level light therapy, using red light and infrared light.
