Why You Need SPF 100 — and the Best Sunscreens to Buy This Summer

Memorial Day Weekend has come and gone, meaning the unofficial start of summer is already here. And though there’s plenty to look forward to in the coming months (Hello, BBQ season!) there’s one thing we all fear: the dreaded sunburn.

Luckily, it’s easier than ever to protect yourself from the sun’s harmful rays. But just how protected do you need to be? According to a new analysis published in the Journal of the American Academy of Dermatology, everyone should be rocking SPF 100 all summer long.

According to the researchers, wearing SPF 50 sunscreen simply won’t cut it as it can lead to significantly more sun-induced skin damage than if you were wearing SPF 100 or more.

But what does SPF mean anyway? As Sejal Shah, a dermatologist in New York City, explained to Allure, SPF stands for "sun protection factor” and indicates how much sun exposure you're actually getting when you're outside. "SPF 15 protects against 93 percent of UVB rays, SPF 30 protects against 97 percent, and SPF 50 is about 98 percent," Shah said.

SPF 100, on the other hand, will keep out 99 percent.

“It doesn’t sound like much of a difference, but if you look at it the other way, you’re getting twice the exposure with the 50 than with the 100,” Darrell Rigel, dermatologist and co-author of the new SPF study, told The Cut. “Cumulatively over time, that adds up. The analogy I give is: there are two taxis. In one taxi the meter is going twice as fast. Over time, you’re going to damage your skin twice as fast.”
