How do I avoid white cast from mineral sunscreen?
Look for tinted mineral sunscreens that include iron oxides these blend into most skin tones and actually provide additional protection against visible light. Formulas that use micronized or nano zinc oxide also produce less white cast, though they may be slightly less effective at blocking visible light. Applying the sunscreen in thin, layered coats rather than one thick application also helps it blend more seamlessly.
