UV Index Exposure Risk Gauge
Estimate burn time, SPF protection time, and reapplication interval from UV index and skin type.
What this means
Recommended SPF for this UV: SPF 30-50.
Formula used
Burn time = base minutes / UV * 3; SPF multiplies protection and water halves it.

Common questions
Can I use this internationally?
Yes. Currency selectors are display-only unless a tool explicitly says otherwise; no currency conversion is performed.
How exact is the result?
It follows the published Technofatty formula for this tool, but real life can add fees, rules, timing quirks, and context.
Plain-English summary
UV 7 with skin type II: burn time about 4 minutes.
This section translates the result into a short, direct takeaway rather than leaving the page at a bare number.
