Deep Red LED Mask from Monastery. This at home treatment mask features the deepest-colored bulbs on the market — a rich burgundy hue, unlike the orange-red tones commonly used in other devices. This deeper red light saturates the skin cells more effectively with a high irradiance of 35mw/cm² at the 660-nanometer wavelength. This ensures optimal energy absorption into the skin, boosting collagen production and promoting cellular turnover with professional-grade efficiency. With 470 LEDs — more bulbs per square inch than most devices — The Deep Red ensures uniform coverage for consistent, all-over treatment. This non-invasive at home treatment helps to stimulate collagen production, reduce fine lines, improve circulation and calm inflammation. This professional tool is the strongest and safest tool you can use at-home to experience the benefits of professional-grade light therapy.
