Sodium salt of hyaluronic acid. Structurally more stable than the acid itself and more common in formulations. Molecular weight determines behaviour: high-MW (> 1 MDa) holds water at the surface, low-MW (< 50 kDa) penetrates deeper. Cosmetics typically use a mix of MWs. A baseline moisturising active across all segments.
Topical application
AProven efficacy. Two or more independent RCTs with instrumental endpoints.
Moisturising effect is demonstrated in dozens of RCTs. When applied topically it retains water in the stratum corneum and visually plumps fine lines. Efficacy depends on molecular weight and concentration (typically 0.1-2%). Does not replace barrier lipids but combines well with them.
Irritation potential
LowAllergen risk
LowPregnancy
