Have you ever roamed the sunscreen aisle and wondered exactly what the term SPF meant?
SPF is the measure of the sunscreen's ability to protect the skin from UVB rays –– the kind of radiation that causes sunburns.
Let's break is down like this:
If your skin normally burns after 10 minutes, applying an SPF 15 would allow you to stay in the sun (without burning) for about 150 minutes. If it takes 20 minutes, using an SPF 15 sunscreen is meant to protect you for 15 times longer.
However, you still need to reapply sunscreen every two hours. This is VERY important and an important tip to know in order to stay extra sun safe this summer.
