What Iron is & what it does
Iron, listed as the elemental metal, is most often present in cosmetics in the form of its oxide pigments rather than as free metal. In that pigment role it contributes color and opacity and can help products in the red, yellow, and brown range. When the listing reflects iron oxides, these are well-established, stable mineral colorants widely used in tinted and mineral sunscreens. The ingredient is generally regarded as inert and non-reactive on skin.
