Functions
Humectant
A moisture magnet. Pulls water from the air and deeper skin layers up to the surface to keep skin plump and hydrated.
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Locks In Moisture
Traditional Use
The sodium salt form of hyaluronic acid, developed as a more stable, smaller-molecular-weight derivative for cosmetic use. Became popular in skincare formulations from the 1990s onward as a humectant with superior penetration compared to high-molecular-weight hyaluronic acid.
