Our LED Neck & Décolletage Mask features 50 LEDs that emit the two most clinically recognized wavelengths for anti-aging: red at 633nm and infrared at 830nm. Red light wakes up your skin's collagen production, helping to reduce the signs of aging, while infrared light energizes the cells below your skin, resulting in a firmer, tighter, and brighter complexion. Visible Anti-Aging Patented pillow technology Our patented Pillow Technology improves skin coverage by diffusing the LED wavelengths across the neck and chest area. Each LED is embedded in a transparent silicone case within the flexible mask, which diffuses the light to boost skin coverage for maximum results. Fast shipping.
