Know exactly when to tan.

    Tanning 101

    Tan smarter with the science.

    Three quick tools that explain how skin, UV, and burn time actually work. The same math Sundaze runs under the hood.

    Skin Type

    The Fitzpatrick scale ranks skin from Type 1 (always burns) to Type 6 (rarely burns). Tap a type to see what it means.

    Type III
    Medium skin. Sometimes burns mildly, tans gradually to a light brown. The most common type globally.

    UV Index Levels

    UV runs from 0 to 11+. Same color scale Sundaze uses across the app.

    Burn Time Calculator

    Pick your UV and your skin type. Get the minutes of unprotected exposure before redness starts. Same chart Sundaze uses.

    UV Index 8
