How do you know if sunscreen is working?
There are a few ways to tell if your sunscreen is working:
The first way is to look at the SPF (sun protection factor). The higher the SPF the better protection your sunscreen will offer. However even the highest SPF will not block all of the sun's rays so it's important to reapply regularly and stay out of the sun during peak hours (10am-2pm).
Another way to tell if your sunscreen is working is to check the expiration date. Sunscreen expires after a certain amount of time so if you're using an expired product it probably won't work as well.
Finally if you're using a physical sunscreen (one with zinc oxide or titanium dioxide) you should be able to see a white film on your skin. If you can't see this film it means that the sunscreen has been rubbed off and you'll need to reapply.
