Hollow polymer microspheres. They give a light airy texture and softly fill in unevenness and smooth skin relief. Inert to skin.
Topical application
BLimited evidence. One RCT or several controlled studies with limitations.
Functional texturizing microspheres. Safe.
Expancel microspheres (INCI: Acrylonitrile/Methyl Methacrylate/Vinylidene Chloride Copolymer) are hollow polymer microspheres. In formulas they give a light, airy texture, softly fill in irregularities and create an optical effect of smoother relief. This is a functional ingredient with a purely sensory and optical effect. The smoothing it provides is cosmetic and instant, sitting on the surface; it does not change the skin or treat real wrinkles. To improve a formula's feel and finish it works, without promising more. Topically it is inert and not meaningfully absorbed, so it can be used during pregnancy and breastfeeding. Tolerance is good: irritation and allergy risk are both low. Since these are particles that stay on the surface without penetrating, they rarely cause discomfort, even on sensitive skin.
