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. You'll find it in our Ruby Rose for a rosy glow, Calm Bronze for sun-kissed warmth, and Blackberry Vanilla for deeper berry tones. It's combined with iron oxides for color and suspended in our butter base for smooth application. We also use mica in many of our soap bars to create the swirls, shimmers, and visual dimension you see on the surface.
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.
