Mica
Part of our Ingredient Glossary — educational information about raw materials we may use in our products. We don't sell raw ingredients.
Mica is what gives shimmer its shimmer. This silicate mineral forms in layered, sheet-like crystals that reflect light in soft, diffused patterns. Unlike synthetic glitter (which is essentially tiny plastic mirrors), mica creates luminosity that looks natural. It catches light without screaming for attention.
The mineral has been used in cosmetics for thousands of years. Ancient Egyptians ground mica into their eye makeup. The Aztecs used it in ceremonial pigments. Today, cosmetic-grade mica is refined to remove impurities and ensure consistency, but the basic principle remains unchanged: thin mineral sheets reflecting light.
In our shimmer sticks, mica provides the luminescent quality that makes skin look healthy and lit-from-within rather than made-up. It's often combined with iron oxides (for color) and suspended in our butter base (for application). The result is color and shimmer that blend seamlessly with your natural skin.
A note on sourcing: the cosmetics industry has faced scrutiny over mica mining practices, particularly regarding child labor in some regions. We work with suppliers who can verify ethical sourcing and chain of custody. This costs more. It's worth it.
``` --- ### 2. Iron Oxides ``` Display Name: Iron Oxides URL Handle: iron-oxides Pop-up Summary: Earth-derived pigments that have colored human art and adornment since prehistory. These stable, non-toxic minerals create the reds, yellows, browns, and blacks in our natural makeup. Brief Description: Iron oxides are mineral pigments derived from iron ore. Different oxidation states create different colors: red (ferric oxide), yellow (ferric hydroxide), and black (ferrous-ferric oxide). We use cosmetic-grade iron oxides to create safe, stable, vibrant color in our makeup products. Best Suited For: All skin types. One of the most stable and non-reactive colorants available. Suitable for sensitive skin and eye area. The Science: Three primary forms create the full color spectrum: red (Fe2O3), yellow (FeOOH), and black (Fe3O4); Extremely stable and resistant to light, heat, and pH changes; Non-toxic and approved for use around eyes and lips; Synthetic versions are purer and more consistent than mined, with no heavy metal contamination Tags: I, Minerals, Iron Oxides
