Iron Oxides

What is it

What are Iron Oxides?

Iron oxides are naturally occurring mineral pigments long used in cosmetics for their color properties - but they have emerged as a clinically significant ingredient in modern sun protection. Unlike traditional sunscreen filters that only address UV radiation, iron oxides protect against visible light - a portion of the light spectrum that can independently trigger melanin production and worsen conditions like melasma. Their inclusion in tinted mineral sunscreens is a deliberate clinical decision, not just a cosmetic one.
