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
