A fermented-sugar polysaccharide used as a light film-forming humectant and texture agent.
What it does
Dextran is a polysaccharide made by fermenting sugar. It holds water at the skin surface, forms a light smoothing film, and adds body to a formula, so it is used as a humectant and texture helper. It is a hydration-and-texture ingredient rather than a skin active.
