Swimming? Sweating? Here's How Fast Your Sunscreen Wears Off

Sunscreen is a must-have summer staple, but using it correctly might require an updated skincare routine.

Whether you are swimming, sweating, or even just working in your garden, sunscreen wears off, leaving you exposed to harmful rays that lead to blisters, sunburns, and a higher risk of skin cancer.

Skincare experts say many people aren’t applying enough sunscreen and they aren’t applying it often enough to prevent skin damage.

Here’s what you need to know about protecting your skin:

Apply Sunscreen And Give It Time To Dry

And don’t forget to use enough every time you apply. The MD Anderson Cancer Center recommends one ounce of sunscreen, or about a golf ball sized amount, to every part of your body that will be exposed.

Keep An Eye On The Time And Reapply Often

Reapply your sunscreen every two hours, especially if you are swimming or sweating, Johns Hopkins Medicine recommends. Everyone should follow this advice, whether you are spending the day at the beach, or mowing your lawn. Headed out for a walk during your lunch hour? Yup, reapply.

Not All Sunscreen Is Created Equal

The type and strength of sunscreen needed to protect your skin depends on how long you will be out in the sun. The SPF in moisturizers and cosmetics will often not be enough for high sun exposure. The U.S. Food & Drug Administration recommends a minimum of SPF 15 to keep you protected if you will be indoors most of the time, with brief exposure to the sun. SPF 30 or above is recommended for extended exposure or for those with fair skin.

No matter which type of sunscreen you use, don’t forget to apply it as many times as you need during the day.

Don’t Forget To Accessorize

Sunscreen is necessary to protect your skin from harmful UVB and UVA rays, but it’s not the only option. Experts recommend using wide-brimmed hats, tightly woven long-sleeve shirts or sun-protective clothing, and sunglasses with UV protection.
