The COSRX Hydrium Triple Hyaluronic Water Wave Mask is a skincare product formulated with a combination of hyaluronic acid compounds known for their hydrating properties. Hyaluronic acid is a glycosaminoglycan that naturally occurs in the skin, providing structure and moisture retention abilities. The three types of hyaluronic acid present in this mask are low molecular weight, medium molecular weight, and high molecular weight, each offering unique benefits. Low molecular weight hyaluronic acid penetrates the skin more easily due to its smaller size, delivering hydration to deeper layers and promoting firmness and elasticity. Medium molecular weight hyaluronic acid works on the skin's surface, improving the skin's moisture content and overall appearance. High molecular weight hyaluronic acid forms a protective barrier on the skin, preventing moisture loss and enhancing the skin's natural defenses against external aggressors. Additionally, the COSRX Hydrium Triple Hyaluronic Water Wave Mask contains panthenol (provitamin B5), a humectant and skin conditioning agent that attracts and retains moisture, promoting soft and supple skin. Panthenol also supports skin barrier function, helping to protect against environmental stressors and maintain skin integrity. The pH of the COSRX Hydrium Triple Hyaluronic Water Wave Mask is carefully balanced to optimize skin compatibility, while its lightweight texture ensures easy absorption without leaving a greasy residue.
