How long can skin type VI tan without burning?
Fitzpatrick type VI (almost never burns, always tans) reaches the first redness after about 50 min at UV 8, 80 min at UV 5 and 2 h 13 at UV 3, with no sunscreen. No level is risk-free for any skin type — these estimate when to come in.
A weather-based estimate, not a personal safety limit. Skin damage builds up before any redness shows. Do not rely on these times for children, or if you have a history of skin cancer, a skin condition, or take photosensitising medication.
Deeply pigmented dark brown to black skin.

What type VI actually means
At 600 J/m², type VI has three times the tolerance of type I: 50 minutes at UV 8 against 17. The natural protection of deeply pigmented skin is real and it is roughly equivalent to a low-factor sunscreen — not to an absence of exposure.
How to recognise it: Type VI is deeply pigmented skin that almost never burns. It still receives UV, and the numbers on this site still apply — they are simply longer.
What to do: The relevant risk for type VI is not sunburn but cumulative dose, and the places where it stops being theoretical are the equator, the mountains and the snow.
Where type VI sits among the six
- Type I 17 min at UV 8 · MED 200 J/m²
- Type II 21 min at UV 8 · MED 250 J/m²
- Type III 25 min at UV 8 · MED 300 J/m²
- Type IV 33 min at UV 8 · MED 400 J/m²
- Type V 42 min at UV 8 · MED 500 J/m²
- Type VI 50 min at UV 8 · MED 600 J/m²

Skin type VI — the questions people actually ask
How long can skin type VI stay in the sun?
It depends entirely on the UV index, not on the temperature or the season. Type VI has a minimal erythemal dose of 600 J/m², which gives about 2 h 13 at UV 3, 80 min at UV 5, 50 min at UV 8 and 36 min at UV 11, with no sunscreen and a clear sky. Those figures mark where damage becomes visible, not a safe allowance to use up.
What UV index is safe for skin type VI?
None, in the risk-free sense — a tan is type VI's response to UV damage like any other skin type's, and the index only sets the speed. The World Health Organization recommends sun protection from UV 3 upward for everyone. What changes with type VI is the clock: about 2 h 13 to visible redness at UV 3 against 50 min at UV 8.
Am I skin type VI?
Deeply pigmented dark brown to black skin. Almost never burns, always tans. Type VI is deeply pigmented skin that almost never burns. It still receives UV, and the numbers on this site still apply — they are simply longer.
How much does sunscreen change things for type VI?
It slows the dose without cancelling it: no sunscreen filters 100% of UV, and the protection you actually get depends on how much you applied and how long ago. For type VI the rule that matters at UV 8 is reapplication every two hours plus shade at the peak, not a multiplication of the 50 min above.
