Mica

Mica is a naturally occurring silicate mineral with a distinctive layered crystalline structure that creates a characteristic pearlescent shimmer and light-reflecting properties. Formulators prize it for its ability to impart luminosity and a soft-focus effect to cosmetics, particularly in makeup products, while its plate-like particles help improve product adhesion and slip on skin. It serves as both a base for pearl pigments (when coated with titanium dioxide or iron oxides) and as a texturizing agent that enhances the sensory experience of cosmetic formulations.
