Sodium hyaluronate is the sodium salt of hyaluronic acid. The substance is able to bind 1000 times its own weight in water and is mainly used in skin care cosmetics due to its moisturizing properties.

Just like hyaluronic acid which is almost identical in its mode of action, it supports the skin to better absorb and store moisture. By replenishing the moisture depots in the skin it has a cushioning and smoothing effect.
