Iron Oxides
Mineral pigments – red (CI 77491), yellow (CI 77492), black (CI 77499). Color foundations, BB creams, eyeshadows, lipsticks, and mineral sunscreens. They also block visible light – the only pigments that protect against HEV/blue light. Safe during pregnancy and for sensitive skin.
Evidence by route
Topical application
BLimited evidence. One RCT or several controlled studies with limitations.
Beyond color, RCTs (Boukari 2015, Ferrand 2014) show that iron oxides combined with mineral UV filters reduce visible-light and HEV-induced pigmentation by 60-100% in melasma and PIH patients. This is why tinted sunscreens are recommended for hyperpigmentation.
