The Whitening Collagen Bed has a calming and relaxing red light that penetrates the skin to a depth of 8-10mm which increases circulation by the formulation of new capillaries. These new capillaries in turn speed up the healing process of damaged skin. The light rays stimulate the production of collagen, a protein with a high elasticity level that is used to repair damaged tissue.This therapy is beneficial for the treatment of wrinkles, acne, age spots, scars, and sun-damaged skin.
