What it is
A humectant naturally found in skin, capable of holding many times its weight in water — used in products across all molecular weights, from surface-hydrating high-molecular-weight forms to smaller "hydrolyzed" versions marketed for deeper penetration.
How it works
Binds up to 1000x its weight in water; acts as a humectant (sponge that attracts moisture)that draws moisture into the epidermis, temporarily plumping the skin surface — hydration-driven, not a collagen-building mechanism.
