This is where I should tell you which mineral sunscreens (that is, those using zinc oxide to protect against UV, rather than the modern, clearer variety using synthetic filters) are invisible on all skin tones, pale to deep. But I won’t, because I truly don’t believe one exists.
I hear recommendations given in all sincerity (and I’ve made some myself), but given what we now know about how much should be applied to the face (1.25ml, or around two full finger lengths), it’s true that even great mineral sunscreens, if used correctly, will show up to some degree.
