Iron Oxides and Colour Pigments
Iron oxides and colour pigments are the mineral-based powders that give most cosmetics their rich, stable shades. From the neutral beige of your foundation to the bold red of your lipstick, these safe, finely milled minerals deliver consistent colour without fading. They are widely used in UK beauty products because they are gentle, non-irritating and perform reliably across creams, powders and liquids.
How it works in skincare
In cosmetics and skincare, iron oxides and other colour pigments are dispersed throughout creams, powders, lipsticks and mascaras to provide immediate, opaque colour. The finely ground mineral particles sit on the skin or hair surface, reflecting specific wavelengths of light to create the desired shade while remaining stable under light exposure and throughout the day. Because they are inert and do not react with other formula ingredients, they allow brands to achieve precise colour matching and long-wearing performance without compromising the texture or feel of the product.

Where it comes from
Iron oxides occur naturally as minerals in the earth’s crust, primarily extracted from hematite, magnetite and limonite ores. They are carefully purified and milled into cosmetic-grade pigments for safe use in beauty products.
