Description of sodium hyaluronate
Sodium hyaluronate is the salt of hyaluronic acid.
Discovered in the 1930s, hyaluronic acid is abundant in the dermis of young skin, but its quantity decreases with age: the skin then appears more damaged, with wrinkles. Hyaluronic acid is a fairly large molecule that has difficulty penetrating the skin, and is much more effective when injected. In a cosmetic, it is its salt that is used: sodium hyaluronate is a much smaller molecule, which penetrates more easily and can then move into the deeper layers of the skin. It is said to be more bioavailable.
It shares the same advantages as hyaluronic acid, including its remarkable ability to help the skin retain a lot of moisture (one gram of hyaluronic acid can contain up to six liters of water). As a “smart” ingredient, when used on the skin sodium hyaluronate helps skin maintain its moisture balance, which is essential for healthy-looking skin.
In addition to its hydrating and plumping properties, sodium hyaluronate is also considered a postbiotic, meaning it can help nourish and maintain the skin’s microbiome.
