MICA

Mica is a mixture of minerals with a layered structure that can be easily split into thin platelets. In cosmetics, mica is used as a so-called effect pigment (glimmer)—for example, to create shine, shimmer, or a light-reflecting finish. Due to its optical and functional properties, mica is a popular ingredient in powders, foundations, eyeshadows, and other decorative products.(1-2)
