Cosmetic-grade sodium hyaluronate is recognized in the industry as an excellent moisturizing ingredient. It not only increases skin hydration but also slows down the formation of dryness-related fine lines by improving the moisture state of the stratum corneum and skin elasticity, helping skin maintain smoothness and firmness. Thanks to its safety, stability, and multi-molecular-weight structure, it has become an indispensable functional ingredient in anti-aging and fine line care products.
