This is the cordless handheld device only available from Hammacher Schlemmer that delivers both red and blue light therapy, helping users diminish wrinkles and rejuvenate skin while also fighting discoloration and blemishes. A study published in a leading German dermatology journal endorsed the use of 650nm red light to counteract the signs of aging, as the light waves penetrate the skin’s surface to boost circulation and amp up collagen production, leaving skin tighter and fuller-looking. Doctors recommend treating skin disorders with 415nm blue light, meanwhile, because this wavelength helps destroy the bacteria and shrink the oil glands associated with acne and other conditions. Users simply select their desired therapy on the device handle, and the octagonal surface area illuminates with 97 LEDs in that color, shining a comfortable, bright light and restoring skin in only 20 minutes of therapy twice a week for four weeks. Device recharges in two hours with the included AC adapter. 7" L x 3" W x 1 1/2" D. (2 lbs.)
