A film-forming polymer. It holds SPF filters and pigments in an even layer and improves wear. Inert to skin.
Topical application
BLimited evidence. One RCT or several controlled studies with limitations.
A functional film former. Safe.
Allyl Stearate/VA Copolymer (INCI same) is a film-forming polymer. In a formula it keeps sunscreen filters and pigments in an even layer and improves the product's resistance to sweat and water. That is why it appears in sunscreens and long-wear makeup. On efficacy: this is a functional film and fixation ingredient, not a skincare active. It does not treat skin. Its real contribution is helping SPF and color spread evenly and last longer, which genuinely matters in a sunscreen. It is topical, with no meaningful systemic absorption. It can be used during pregnancy and breastfeeding. Tolerance is high: low irritation and allergy potential, suitable for sensitive skin. It is an inert polymer that does not clog pores under normal conditions.
