LED face and and neck silicone mask set from Nourished Bodynskin. Used just once, like new condition. Nothing wrong with it, though I didn't like the straps. Specs: 7-Mode Near-Infrared Light Therapy Mask Set: Features seven colors like red and blue lights, each combined with NIR for deeper skin rejuvenation, offering high-precision LEDs with 35 mW/cm² irradiance. Red light: 630nm, NIR light: 850nm. 228 LEDs carefully set in a medical-grade silicone base to target neglected areas like the undereye and upper lips to help soften smile lines. Powered by rechargeable control pack that allows selection of power level, color and time. The control pack can run both the face and chest mask at the same time.
