Water-resistant film polymer
INCI: VP/Eicosene Copolymer
Forms a smudge-resistant film around each lash so the lifted, lengthened look holds through humidity and wear.
Evidence and limitations
Film-forming and wear-resistance functions are documented in polymer suppliers' technical data and established formulation practice; there is no independent peer-reviewed lash research, and none is expected for a film polymer.
