The mineral is similar to talc but is used to create the frost in your lipstick or eye shadow. When you break down mica, it breaks down flat—like a mirror—so, depending on the particle size, you can go from club glitter to frosty to illuminating to just glowy. "When you rub mica into your skin pure, it disappears," describes Casale.
