The LED light treatment mask uses the principle of photodynamic therapy. When the light is absorbed by the skin, the energy of light is converted into intracellular energy and leads to the production of photochemical/enzymatic reaction. The activity of catalase (Catalase) and superoxide dismutase (SOD) in the cell increases. It stimulates the secretion of fibroblast growth factor (BFGF) and epidermal growth factor (EGF). The production of collagen and protein is increased, promoting the synthesis of new cells that replace the old ones. Collagen fibers rearrange, cell growth is accelerated, blood circulation is enhanced and skin elasticity is increased. In combination with other treatments it restores aging skin, acne skin while it also promotes skin hydration and tightening.
