Skin Type I (Very fair)
Pale white skin, often with red or blond hair, light eyes and freckles. Always burns, never tans.
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
Pale white skin, often with red or blond hair, light eyes and freckles. Always burns, never tans. 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 are at the highest risk of burning and need the most protection: high-SPF sunscreen, a hat, sunglasses and shade in the middle of the day, even when it is cloudy or you are near snow or water, which bounce UV back at you.
What it means for vitamin D
Your skin makes vitamin D quickly, but you will usually burn long before spending a "useful" amount of time in strong sun — so a few short exposures beat one long one, and diet or supplements matter in winter. 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.
