You've got that glow

A light-therapy machine called ReGen, produced by Energist, in Swansea, Wales, uses highintensity 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.
