What is SPF?
SPF means Sun Protection Factor and the number refers to the measure of effectiveness of the sunscreen. The SPF number is the indication of time duration the sunscreen will be able to protect your skin.
How to calculate SPF?
Select your skin type according to the amount your skin can safely stay in the sun before burning. We call it "Burn Time".
Fair skin - 10 min
Olive skin - 15 min
Dark skin - 20 min
- Check SPF number on your sunscreen.
- Using SPF 50 as an example and a burn time of 10 min.
- 50 *10 = 500 minutes = 8 hours of sun protection
