Polymethyl Methacrylate
Polymethyl Methacrylate · Methyl Methacrylate Crosspolymer
Smooth polymer microspheres used to blur texture and give a soft-focus, silky finish.
What it does
Polymethyl methacrylate is used as tiny smooth polymer spheres. They roll over the skin to fill in fine texture, scatter light for a soft-focus look, and add a silky slip to primers and color products. It is a texture-and-optical ingredient rather than a skin active.
