The COSRX Hydrium Triple Hyaluronic Moisturizing Cleanser is a scientifically formulated skincare product designed to hydrate and cleanse the skin effectively. This cleanser contains three forms of hyaluronic acid, a naturally-occurring compound in the skin known for its superior moisturizing properties. Hyaluronic acid is a glycosaminoglycan composed of repeating units of glucuronic acid and N-acetylglucosamine, which attracts and retains moisture within the skin. The different molecular weights of hyaluronic acid included in this cleanser allow for multi-level hydration, penetrating different layers of the skin for optimal moisture retention. The low molecular weight hyaluronic acid in the formulation enhances skin penetration, providing deep hydration to the epidermis. In contrast, the high molecular weight hyaluronic acid forms a protective barrier on the skin's surface, preventing moisture loss. The medium molecular weight hyaluronic acid contributes to the overall hydration balance of the skin. Additionally, this cleanser contains surfactants that effectively cleanse the skin by removing dirt, oil, and impurities without stripping away its natural oils. The mild cleansing agents maintain the skin's pH balance, ensuring that the skin remains hydrated and comfortable after use. The COSRX Hydrium Triple Hyaluronic Moisturizing Cleanser is formulated to be non-irritating and suitable for all skin types.
