Pullulan (a polysaccharide film-former)
INCI: Pullulan
Forms a light, fast-drying film that sets the serum quickly so mascara or makeup can be applied straight over the top without smudging or transfer.
Evidence and limitations
A recognised film-former in cosmetic science with manufacturer data on its film-forming and tightening behaviour; the fast-dry benefit is a formulation property, not a lash outcome claim.
