Chemical sunscreen vs mineral sunscreen: Chemical wins for avoiding white cast on dark skin

The white cast comes from mineral sunscreens (zinc oxide, titanium dioxide) that sit on skin and reflect UV — great for protection but terrible for dark skin tones. Chemical sunscreens with avobenzone or Tinosorb M go on invisible. If you need mineral for sensitivity, look for micronized or nano versions, or try tinted mineral — but finding the right shade is a hassle. Chemical is simpler and more reliable for avoiding ghost-face.
