Here are some insider tips and tricks to keep your skin glowing and healthy:
Coat Yourself Before You Put on Your Clothes
"Working around your clothes will make you more likely to miss a spot," says dermatologist Jeannette Graf. On your body, slather on a shot glass's worth of a broad-spectrum sunscreen that's at least SPF 30. For your face, you'll need another teaspoon.
Don't Wait Until You're Outside
Another reason why it's good to apply sunscreen before you get dressed: SPF needs a good 20 minutes to sink in before your skin is completely protected from UV rays, Graf says. If you wait, you might as well be wearing no sunblock at all for that first half-hour you're outdoors.
Keep It Fresh
We all have that leftover bottle of sunscreen lurking in the medicine cabinet, but it's critical to start fresh each summer. "The active ingredients in sunscreens can lose their potency, so check the expiration date," says dermatologist David Bank.
Think Ahead
People often forget to protect their scalp—and end up with a burn in their hair part. When in doubt, wear a hat.
