What the Fitzpatrick scale is for
The scale groups skin by typical burn and tanning response. For TanPilot, that input changes burn-risk timing, tanning window suggestions, and reminder urgency.
-
Type I-II
Usually burn easily and tan little or with difficulty. Burn-risk reminders should be early and conservative.
-
Type III-IV
Often tan more gradually or easily, but high UV can still cause redness and damage.
-
Type V-VI
Burn less often, but UV protection still matters for skin and eyes.
