Skin Type IV (Olive / moderate brown)
Olive or moderate brown skin, common around the Mediterranean and parts of Asia and Latin America. Rarely burns, tans easily and well.
General sun-safety information, not medical advice. Burn times vary enormously with skin, the UV index, altitude, reflection off snow or water, and some medicines — when in doubt, cover up. Any new, changing or unusual mole or spot should be checked by a doctor.
How this skin reacts to the sun
Olive or moderate brown skin, common around the Mediterranean and parts of Asia and Latin America. Rarely burns, tans easily and well. Remember that burn time is not fixed — it rises and falls with the UV index, altitude and reflection off snow, water or sand, so the same skin can be fine one day and burnt the next.
Protecting your skin
You burn rarely, but "rarely" is not "never" — intense sun, altitude and reflected UV can still catch you, and sun exposure still ages skin and carries a skin-cancer risk. Protect on the strongest days and watch for any changing moles.
What it means for vitamin D
You need somewhat longer in the sun than fair skin to make the same vitamin D, so winter deficiency at high latitudes is worth keeping an eye on. At high latitudes the winter sun is too weak for anyone to make vitamin D from it, so diet and supplements bridge the gap regardless of skin type.
