Why do some people get sunburns and some people tan?

Updated February 21, 2017 | Factmonster Staff

Humans have many shades of pigment in their skin. Skin with deeper pigment absorbs more of the Sun’s burning rays of light. Anyone, even those with dark skin, can burn if they are exposed to enough sun. Redheads with pale skin are most sensitive to the sun. No matter who you are, use sunscreen to prevent burns. You’ll have healthier skin as you grow.
