Sodium Acetylated Hyaluronate is an acetylated, sodium-salt derivative of hyaluronic acid used in skincare for its enhanced moisture retention and improved skin adherence compared to standard hyaluronic acid. The acetyl modification increases lipophilicity, allowing better surface binding and prolonged hydration.
