Functional texturizing microspheres. Safe.
Methyl Methacrylate Crosspolymer (INCI: Methyl Methacrylate Crosspolymer) consists of spherical polymer microspheres. In a formula they give a soft matte finish, fill fine irregularities and blur skin relief, creating an optical smoothing effect. This is a functional and decorative ingredient, not a treatment active. It improves the feel and immediate look of a product but does not act on skin biology. Its role is texture and finish. The microspheres are inert and do not penetrate, so systemic absorption is nil. It can be used during pregnancy and breastfeeding without restriction. Tolerance is very good. Irritation and allergy risk are low, suitable for sensitive skin. It is not usually linked to clogged pores, though on very oily skin it is worth checking the whole formula.
