INCI: Sodium Acetylated Hyaluronate

In short · TL;DR

Category

Moisturizing

Effect

Offers a feel with better adhesion to the stratum corneum and longer-lasting moisture retention than ordinary hyaluronic acid

Concentration

Roughly 0.01–0.2% in toners and serums (varies by product)

Effect

Offers a feel with better adhesion to the stratum corneum and longer-lasting moisture retention than ordinary hyaluronic acid

Mechanism

Part of the hydroxyl groups of hyaluronic acid is acetylated to impart hydrophobicity. Aims to increase affinity for the stratum corneum and sustain moisture retention

Typical concentration

Roughly 0.01–0.2% in toners and serums (varies by product)

Onset

Moisturizing feel immediately after application; sustained supple feel with continued use

Cautions

Raw-material cost is high, so high loading is rare. Generally low-irritation
