2. SPF Facts
The Mistake: You think "sun protection factor" (SPF) protects against everything.
It doesn't. The ingredients that provide SPF will shield you from only UVB rays. Even so, the protection SPF provides is critical, because UVBs (along with UVAs) play a role in the development of skin cancer.
Experts advise wearing a broad-spectrum sunscreen with an SPF of at least 15. Those who burn easily (blondes, redheads, and anyone with fair skin) should opt for SPF 30. (Research shows that SPFs above 30 do not significantly increase protection.)
