Sodium Hyaluronate
Sodium Hyaluronate · Hydrolyzed Sodium HyaluronateHydrator
Salt form of hyaluronic acid. The form most often used in formulations; better solubility than HA itself.
What it does
Sodium hyaluronate is the sodium salt of hyaluronic acid — the same molecule with better solubility for formulation purposes. Most products marketed as 'hyaluronic acid' technically use sodium hyaluronate on the INCI. Different molecular weights penetrate to different skin layers — small (low MW) reaches deeper, large (high MW) stays at the surface for film-forming hydration.
The evidence, graded
strongHydrating ingredients (hyaluronic acid, glycerin) show immediate plumping and dewy-finish effects within minutes. Barrier-repair products (ceramides, panthenol, niacinamide-as-barrier) show measurable improvement in 1–2 weeks.Pavicic 2011 · Journal of Drugs in Dermatology ↗
