METHYL METHACRYLATE CROSSPOLYMER.

This ingredient functions primarily as a film-forming agent, creating a breathable, continuous polymer film upon application to the skin. Its distinct porous microsphere structure enables efficient absorption of excess sebum and oil, resulting in a pronounced mattifying effect crucial for managing shine and preventing blemishes. Additionally, it serves as a light-scattering agent and opacifier, optically diffusing light to visibly diminish the appearance of pores, fine lines, and other minor imperfections, yielding a 'soft-focus' effect. Beyond direct skin benefits, Methyl Methacrylate Crosspolymer acts as a texture enhancer, contributing to product smoothness and a luxurious silky feel, and improves formulation stability and makeup durability. It can also increase product viscosity and function as a sophisticated carrier system for the controlled release of active ingredients.
