REVIVE is a dual light system designed with two very powerful lights, Pure Blue Light (465nm) and Pure Red Light (640nm). The wavelengths have been carefully selected to help clear skin, fight dull complexion, and restore skin radiance. Alternating between sessions of Red light and Blue light will contribute to faster skin recovery and reduce the risks of scarring. REVIVE offers these two lights at the switch of a button, so go from Red to Blue as you need for the whole face.
