Dmpa/Isophthalic Acid/Smdi Copolymer
Also-called-like-this: Part of ChronoSphere® Opticals
Details
A clear polymer (big molecule from repeated subunits) molecule that is used to coat silica beads to modify its light reflecting properties and create the illusion of a smoother skin surface and obscures imperfections.
Based on the manufacturer's in-vivo (made on real people) tests, 3%-5% ChronoSphere Opticals (the trade name of the technology) makes a pretty visible difference in smoothing out fine lines and wrinkles on the face. Don't forget, this is only an instant fix that lasts until you wash your face, but pretty cool.
