Sodium Hyaluronate Description

Sodium hyaluronate is the salt form of the skin-replenishing ingredient hyaluronic acid. It shares the same benefits as hyaluronic acid, including its remarkable ability to help skin retain a lot of moisture - one gram (or 0.03 oz.) of hyaluronic acid can hold up to six liters of water. Used on skin, it doesn’t hold that much water; instead, as a smart ingredient, sodium hyaluronate helps skin maintain water balance, which is critical to its healthy appearance.

In addition to its moisture-binding (humectant) properties, sodium hyaluronate is also considered a postbiotic, meaning it can help nourish and maintain skin’s microbiome.

The chief difference between hyaluronic acid and sodium hyaluronate is that sodium hyaluronate is more bioavailable – meaning skin more readily absorbs it than hyaluronic acid. This doesn’t necessarily mean it’s better than hyaluronic acid, merely that many skin care products contain both forms, so your skin sees maximum benefits. Both hyaluronic acid and sodium hyaluronate are available in different molecular weights for multi-level results (lower molecular weight can penetrate deeper into skin’s layers, where higher weights deliver immediate results on the surface).
