The term Mica is the name for a group of natural occurring minerals. Although Micas are found in nature, the Mica powders that are certified for cosmetic use are crushed, purified, or refined to make them safe for use on skin.
Micas can be used in lipsticks, lip balms, rouges, foundations, eye shadows, eyeliners and mascaras. Please note that the mica you are using in your cosmetic is safe for eye and lip application. Micas can also be used to colour soaps and candles.
