1 . Fortunately, the days of being spread on thick baby oil and lying in the sun to get you skin yellowish-brown—or more likely burnt—are long over. Many sunscreens work by filtering (过滤) the sun’s ultraviolet (UV) rays to keep them from reaching skin cells and causing the DNA damage that can lead to wrinkles and skin cancer. But in recent years, the safety of some of those filtering chemical ingredients, particularly oxybenzone (氧苯铜), has been in question.
A 2019 study published in JAMA found evidence that oxybenzone is absorbed into the bloodstream, leading to concerns about whether it might affect functions of our body. Oxybenzone has also been detected in breast milk for newborn babies. Because of concerns about higher intake in children, doctors from the American Academy of Pediatrics advise against sunscreen with oxybenzone for kids.
The Environmental Working Group, an activist organization that monitors chemical safety, has called for a ban, but the U.S. Food and Drug Administration considers sunscreens with oxybenzone safe. “It’s uncertain,” says Deborah S. Sarnoff, president of the U.S. Skin Cancer Foundation. “Just because you’re absorbing the chemical doesn’t mean it’s dangerous.” Further study is required.
But oxybenzone is a risk to coral reefs. Hawaii and the U.S. Virgin Islands have banned the sale of sunscreens with oxybenzone. In a 2022 study published in Science, researchers found that some certain sea plants, when exposed to sunlight, turn oxybenzone into energy or something needed in a way that damages and kills corals.
Some companies have been trying to stop using oxybenzone gradually in stages, and many big brands offer oxybenzone-free options. For anyone who is pregnant or breastfeeding, or simply looking to avoid these chemical filters, Dr. Sarnoff recommends mineral sunscreens, which contain mainly physical barriers.
