Methyl Methacrylate/Glycol Dimethacrylate Crosspolymer
A polymer related to the PMMA beads in primers, used for texture.
What it does
It’s a polymer related to polymethyl methacrylate (PMMA), with its chains tied into a network. It forms a film and thickens. It’s there for texture, not to change your skin.
The evidence, graded
expert consensusUS safety reviewers (2011) assessed polymethyl methacrylate (PMMA), methyl methacrylate crosspolymer and methyl methacrylate/glycol dimethacrylate crosspolymer, which products use to form a film or thicken. They based their verdict on the US FDA’s safety review of PMMA in medical devices, since the PMMA in cosmetics is substantially the same, and judged all three safe as used.Becker 2011 · International Journal of Toxicology ↗
