7 Sunscreen Tips and Tricks From Dermatologists — Expert Recs

“However, in the real world, we do not apply as much sunscreen as we should, and we do not reapply,” Zeichner says. “This ultimately means that the SPF value is diluted out. Starting out with a higher SPF to begin with serves as a safety net to ensure the highest quality of protection for the longest period of time.”

4. You should reapply every couple of hours.

“Ideally, sunscreen should be reapplied every two hours, or more frequently if you are swimming or sweating heavily,” says Zeichner. “The best time to apply sunscreen is before you go outside because there are [fewer] distractions and you can make sure that you have adequately covered all exposed skin areas.”

As for how much, Tanzi recommends about a thin layer on both the face and body, which equals a shot glass’s worth for the entire body and a dime-sized dollop for the face.

5. Mineral sunscreen is dermatologist-recommend.

Blame it on chemical sunscreens’ controversial ingredient list (and how it could be potentially harming the world’s coral reefs), but dermatologists seem to all agree that mineral sunscreen is your best bet for sun protection.

“I really like mineral sunscreen formulas with zinc and titanium because they’re natural ingredients,” says Tanzi. “These physical sunscreens sit on the surface of the skin to deflect the rays.” Even better, mineral formulas are better suited for those with sensitive skin, as they don’t irritate the skin. We love the Best of Beauty 2019 winner for this. The Unsun Mineral Tinted Sunscreen SPF 30 is great because it leaves behind no white cast making it a winner for all skin tones.

6. Your clothes can count as SPF, too.

Sun protection doesn’t just involve slathering on sunscreen. “Be sure to wear sun-protective clothing, hat, and sunglasses,” says New York City board-certified dermatologist Amy B. Wechsler. “I know I sound like a maniac, but UV exposure is the number one cause of premature aging in the scan as well as skin cancer.”

7. Your lips need protecting, too.

“People forget to protect their lips and skin cancer in this area can be particularly dangerous,” says Tanzi. ” Everyone needs lip balm with SPF.” Our pick? The Supergoop Play Lip Balm SPF 30 with Acai, it’s packed with rich shea butter and nourishing vitamin E.
