Iron Oxides

Iron oxides are naturally occurring mineral pigments used to give cosmetics a wide range of earthy tones from soft nudes and warm taupes to deep browns, reds and blacks. They provide stable, long-wearing colour in foundations, concealers, eyeshadows, blushes, lipsticks and nail polishes. Safe and non-irritating, they are one of the most commonly used colourants in UK beauty products.

How it works in skincare

In cosmetic formulations iron oxides are finely milled mineral powders that disperse evenly through creams, liquids and powders to deliver consistent, opaque colour. They are chemically inert, light-fast and resistant to moisture, making them ideal for long-wear makeup that stays true from morning to evening. Because they do not penetrate the skin, they sit on the surface to provide even coverage while remaining gentle enough for sensitive skin.

Iron oxides are naturally occurring minerals mined from the earth, primarily composed of iron and oxygen. In cosmetic grades they are highly purified and may also be produced synthetically to ensure consistency and safety.
