HOW TO GET THE FULL PROTECTION FROM YOUR SUNSCREEN
Most people don’t apply sunscreen properly, so they end up getting much less protection than the label promises. Follow these tips to get your full protection.
When to apply? 30 minutes before you go out in the sun.
When to apply again? Every two hours, and immedi- ately after swimming, toweling off or sweating. How much? 1 ounce or about a shot glass full.
Finally, old sunscreen might not give you full protection. Throw out last year’s bottle and start each season with fresh sunscreen.
A DAY AT THE BEACH
If you apply sunscreen properly, one person will use about one-quarter to one-half of an 8-ounce bottle of sunscreen during a day at the beach.
Yes! 1/4 to 1/2 a
bottle EVERY day in intense sun.
How much sunscreen
to apply? One ounce (about a shot glass full)

Pick broad spectrum
Seriously, this much!
