Burning Truth: Is A Higher SPF Better?

Q: Is a higher SPF better to use? 

A: According to the American Academy of Dermatology (AAD), a broad-spectrum sunscreen with an SPF of at least 30 is best for your skin. 

Higher SPFs don't provide that much additional protection. An SPF 15 sunscreen blocks 93 percent of UVB radiation, while an SPF 30 sunscreen blocks nearly 97 percent. And, an SPF 50 blocks an estimated 98 percent of UVB rays. 

According to the FDA, "there is not sufficient data to show that products with SPF values higher than 50 provide greater protection for users than products with SPF values of 50.” 

Relying solely on a high SPF (like 50 or 100) can lead to a sunburn –– causing the consumer to not apply enough sunscreen (should be a shot glass full). No matter what SPF you are using, always remember to reapply every two hours



What is SPF?

Have you ever roamed the sunscreen aisle and wondered exactly what the term SPF meant?

SPF is the measure of the sunscreen's ability to protect the skin from UVB rays –– the kind of radiation that causes sunburns. 

Let's break is down like this:

If your skin normally burns after 10 minutes, applying an SPF 15 would allow you to stay in the sun (without burning) for about 150 minutes. If it takes 20 minutes, using an SPF 15 sunscreen is meant to protect you for 15 times longer.

However, you still need to reapply sunscreen every two hours. This is VERY important and an important tip to know in order to stay extra sun safe this summer.

SPF 30 Sunscreen May Prevent Skin Cancer By 80 Percent

A new study from Ohio State University found that applying sunscreen reduces the risk of skin cancer by 80%.

“We have developed a mouse model that allows us to test the ability of a sunscreen to not only prevent burns but also to prevent melanoma…. We hope that this model will lead to breakthroughs in melanoma prevention,” Christin Burd, assistant professor of molecular genetics at Ohio State University

The new study tested various SPF 30 sunscreens, and found all delayed the onset of melanoma.

According to the American Academy of Dermatology, skin cancer affects 1 in 5 Americans, and more than 73,000 are expected to be diagnosed with melanoma this year. Don't forget to apply (and reapply) your sunscreen this summer!
