What it does for you
Adds a soft, cushioned feel and helps hold water at the surface.
Why we use it
Chosen for how it makes the formula behave on skin. We include it for texture and surface hydration, not as a headline active.
Mechanism
Like other large polysaccharides, it holds water in a film at the skin surface, slowing evaporation.
Commonly confused with
Often described as a natural alternative to hyaluronic acid. That is a marketing analogy, not a tested equivalence, and we do not use it as a substitute.
