Shimmer, reflective, luster, pearlessence — whatever you call it, the multitasking wonder known as mica is probably in it. Mined from the earth in thin sheets, this mineral is finely ground for use in cosmetics such as eyeshadow, mineral makeup, powder, lipstick, and even nail polish.
The word mica comes from the Latin word "micare," meaning to shine or glitter. Used as an alternative to talc, mica gives a buildable, yet translucent glow to skin, making it a perfect ingredient for use in cosmetics. Who can resist a mineral that can help hide imperfections and fine lines, provide natural UV protection, and adhere smoothly to the skin? Oh, and if you already aren't wowed by its amazing abilities, it's also very safe — regulated by the FDA, this mineral is neither toxic or reactive.
