The new generation of LED masks for rejuvenation is here. Etherna The Rejuvenator is equipped with convex LED lights, the same type used in professional settings, ensuring deeper penetration and more effective results. With five wavelengths, it works both on the surface and deep beneath the skin, targeting acne, eczema, and other visible skin concerns. Deep effects include stimulating collagen and elastin production, which reduces wrinkles and improves skin firmness. Wavelengths & light: Blue (415 nm) Yellow (590 nm) Red (630 nm) Near-Infrared (850 nm) Near-Infrared (1072 nm) The unique combination makes it far more effective than simpler consumer products. The mask also has a longer battery time than most competitors. This is the choice of red-light expert Fredrik Paulún, author of the book Light Revolution.
