Put it on repeat! Re-apply your sunscreen every 2 hours because sweat tends to make your sunscreen patchy over time, which in turn reduces the protection you’re getting. This, of course, is an average time frame, which may decrease for people with sensitive skin who might want to reapply it every 1 hour. With sunscreens becoming versatile in the form of spray sunscreens, stick sunscreens and so on, reapplication has become a lot easier. Shop your fave sunscreens and have a happy, tan-free summer!
