Even black people can get this thing happening, because they have milano sites that produce different chemicals. And when you are more fair skinned, because of a lack of those chemicals, you do get burnt way worse. But it's a myth to think that putting on sunscreen will protect you from sunburn or dna damage regardless of how tanned you are.
