How can I avoid white cast from sunscreen on dark skin?

Use a chemical sunscreen with ingredients like avobenzone, octocrylene, or Tinosorb M — they’re invisible once rubbed in. If you prefer mineral sunscreen, look for “micronized” or “nano” versions, or try a tinted mineral sunscreen, though finding the right shade for dark skin can be tricky. Test on your jawline before buying full-size.
