What are Mineral Cosmetics?

OK guys...this is taken from my website :

Mineral makeup is simply the most simple, natural product you can put on your skin. "Mineral makeup" takes its inspiration from minerals and inorganic pigments that exist in nature, which are finely milled and purified, then treated or coated with other pigments to create different colors and effects. Some mineral pigments are matte, some have a slight shimmer, and some are positively sparkling! Endless combinations of these beautifully colored minerals, such as mica, titanium dioxide, zinc and iron oxides, can be created to make every cosmetic from foundation to eyeshadow to shimmer powder for the body!

Ciel Minerals has taken these finely milled, cosmetic-grade mineral pigments and formulated them together to create our own unique color palette. You can use our products just as they come, or mix them together in various combinations, making new color creations that are perfect for you.

Mica, for example, is a transparent mineral which is mined from the earth in thin sheets. It can be opalescent and sparkling or completely matte, ranging in color from grey to blue to green. It is often treated with iron oxides to yield brilliant color effects. Due to the sheer, translucent and skin-hugging effect of the mica mineral, your natural skin tone shines through when you use our blush, facial powders or eye shadows. All of our cosmetics contain mica powder, which reflects light from the face, creating an illusion of a smoother, softer and more radiant skin tone. Fine lines are softened; skin texture appears more even and more lucid.
