6 Things to Know About Sunscreen Reapplication

Reapply sunscreen every 40 to 80 minutes when swimming or sweating heavily. Check the label for the exact time.

Sunscreens labeled “water resistant” are tested for either 40 or 80 minutes. That number is the maximum time before reapplication is needed.

Most people do not reapply enough. Water, toweling off, and sweat remove sunscreen even if it feels like it is still there.

Spray sunscreens often cause missed spots. The FDA requires water resistance testing, but it does not account for movement or wiping your face.

Reapply after every swim, after every heavy sweat session, and after drying off with a towel. Set an alarm if you are outside all day.

Buy a sunscreen labeled “80-minute water resistant” and reapply every hour. Your skin will benefit from the consistency.
