Myth #7: You don’t need sunscreen in the winter.

It’s cold and cloudy, so you can retire your sunscreen until sunny days at the beach this summer, right? Wrong, says Debra Jaliman, MD, a New York City–based dermatologist. “The sun and UV rays are present winter, spring, summer and fall,” she says. “I recommend that you wear a sunscreen with SPF 30, and it’s best to wear a UVA/UVB blocker. The best ones contain zinc or titanium.”
