Sodium Acetylated Hyaluronate
Sodium Acetylated Hyaluronate is a modified form of hyaluronic acid that has been acetylated to make it more oil-soluble. This allows it to penetrate deeper into the skin than regular hyaluronic acid while still providing excellent hydration. It is a popular ingredient in modern UK skincare serums, creams and sheet masks for delivering long-lasting moisture.
How it works in skincare
In cosmetics and skincare, Sodium Acetylated Hyaluronate works by combining the intense water-binding ability of hyaluronic acid with improved skin affinity thanks to the addition of acetyl groups. This modification gives it both hydrophilic and lipophilic properties, enabling it to penetrate the upper layers of the stratum corneum more effectively than standard HA. Once there it helps bind moisture, smooth the skin’s surface and support a healthy skin barrier without leaving a sticky residue.

Where it comes from
While hyaluronic acid is naturally found in the human body, the cosmetic grade Sodium Acetylated Hyaluronate is produced by fermentation of plant-derived sugars (typically from corn or soy) followed by acetylation.
