Does tinted mineral sunscreen protect against visible light?

Short answerYesModerate evidence: At least one human study or a well-supported mechanism, but not yet full scientific consensus.

Yes — a cited synergy. Iron oxides in tinted mineral sunscreen extend protection into visible light, which UV-only filters miss — meaningful for visible-light-driven pigment disorders like melasma.
