A functional polymer. Safe.
Polymethyl Methacrylate (PMMA) is a synthetic polymer in the form of fine spheres. INCI: Polymethyl Methacrylate. In a formula it works as a texturizing and soft-focus component: it visually smooths skin relief, mattifies, gives a smooth slip, and sometimes carries other substances. It is a functional sensory component, not a skincare active. It is used in primers, foundations, and pore-blurring creams. Environmental caveat. PMMA in microparticle form is classed as a synthetic microplastic, whose use in rinse-off products is being phased down in the EU under the REACH regulation. Manufacturers are moving to degradable alternatives. Pregnancy safety and tolerance. It is inert, does not penetrate skin, and its irritation and allergen potential are low. It can be used during pregnancy and lactation.

The Evigrade extension adds an evidence panel to iHerb, Sephora, Druni and 12 more stores. This ingredient and every other one in the product show evidence-tier, allergen risk and pregnancy/lactation flags at a glance.
Polymethyl Methacrylate is considered safe during pregnancy at typical cosmetic concentrations. Systemic absorption through the skin is minimal.
Polymethyl Methacrylate suits: normal, dry, combination, oily, sensitive.
