Mica
Appears in 2 scanned products.
A naturally occurring mineral that forms in thin, shiny sheets, ground into fine powder for cosmetic use. It is often coated with other pigments to create shimmer effects.
Why it’s used
It gives cosmetics and soaps a pearlescent or shimmering finish and is used purely for visual effect.
What the evidence says
Mica itself carries no credible safety concern at cosmetic use levels. Ongoing scrutiny in the industry has focused less on mica's chemistry and more on labor conditions in some mining regions, which is a supply-chain and ethics issue rather than a matter of ingredient safety on skin.
Context
Used in both rinse-off and leave-on products purely for color and shimmer; concentration has no meaningful safety implication either way.
