The difference between thirty and one hundred is obvious: one hundred is bigger, older, and wiser. In the case of SPF protection, the same holds true, right?

As a consumer, it’s important to understand that even though the SPF is dramatically higher, you are only getting a fraction of a difference in protection. Regardless of how high you go, the FDA recommends using sunscreen with an SPF of at least 15. Whether you opt for a factor of 15 or 50, however, don’t skimp on the amount of sunscreen, use liberally and frequently (at least every two hours and again after sweating or swimming).
