[...] with bottles and tubes covered with claims, "it's really hard to make sense of what all the terminology means," says Roopal V. Kundu, M.D., an associate professor of dermatology at the Northwestern University Feinberg School of Medicine, who researches how people buy and use sunscreen.
Here, then, is the help you need: seven common terms and what they actually mean—and don't. The federal government requires sunscreen claims to be "truthful and not misleading." But only three of the main claims consumers see—"SPF," "broad-spectrum," and "water-resistant"—are strictly regulated by the [U.S.] government and therefore have agreed-upon definitions.

The article goes on to explain those terms as well as "sport," "dermatologist recommended," "natural," "mineral" and "reef safe."

Lighter skinned black people and mixed people of certain racial makeups definitely burn just as easy as white people.
However I have heard from non-black, but swarthy complected people, that some of them darken in hue as sunlight increases and don't burn unless they are out all day. One black woman I know, who was dark, but not overly so, didn't burn herself, nor did her mother, but her kids did as a result of her husband, who was of mostly spanish descent and apparently burned easily.
On the other hand, in exchange for good sun protection, many darker skinned black people have a vitamin deficiency (I think b12 or d) in reduced sunlight environments because their skin protects them from UV TOO well and keeps them from producing the vitamin metabolically in their skin, like they otherwise would.
