A person's natural skin color affects their reaction to exposure to sunlight. An individual's natural skin color can vary from a dark brown to a nearly colorless pigmentation, which may appear white. In 1975, Harvard dermatologist Thomas B. Fitzpatrick devised the Fitzpatrick scale which described the common tanning behavior of various skin types, as follows:
Type | Also called | Sunburning | Tanning behavior | von Luschan scale |
---|---|---|---|---|
I | Very light or pale | Often | Occasionally | 1–5 |
II | Light or light-skinned | Usually | Sometimes | 6–10 |
III | Light intermediate | Rarely | Usually | 11–15 |
IV | Dark intermediate | Rarely | Often | 16–21 |
V | Dark or "brown" type | No | Sometimes darkens | 22–28 |
VI | Very dark or "black" type | No | Naturally black-brown skin | 29–36 |
