Pullulan
A fermented-sugar polysaccharide used as a film-former that gives a smooth, temporary tightening feel.
What it does
Pullulan is a polysaccharide made by fermenting starch. As it dries it forms a thin, flexible film on the skin surface that delivers a smooth, momentarily taut feel and can hold other ingredients in place. It is a film-forming and texture ingredient rather than a skin active.
