A light-therapy machine called ReGen, produced by Energist, in Swansea, Wales, uses high-intensity LEDs, which the company claims will soften skin, smooth wrinkles, and erase blemishes. Each of the four light boxes has a 255- by 70-millimeter panel containing 1024 LEDs. At wavelengths of 415 nanometers, they glow blue; when they’re set at 630 nm, they’re red. A third mode—which produces purple light by mixing blue and red—is claimed to combine the benefits of both treatments. Twenty minutes twice a week is supposed to reduce the signs of aging.
