Environmentalists have also taken issue with chemical sunscreens, and have found that the ingredients oxybenzone and octinoxate are damaging to coral reefs. In January 2020 the FDA shared results of a clinical study that shows six of these ingredients- avobenzone, oxybenzone, octocrylene, homosalate, octisalate, and octinoxate-enter the bloodstream after one application, which could potentially be associated long-term health issues. (Check out our guide to the best mineral sunscreens for our favorites.) The FDA called for more research regarding the other 12, which are typically found in chemical sunscreens. Meanwhile, PABA and trolamine salicylate were deemed unsafe. Out of the 16 currently approved sunscreen ingredients brands can use, the only two deemed officially safe were the physical blockers, zinc oxide and titanium dioxide. But in May 2019 the FDA proposed new regulations for chemical sunscreens because of increasing safety concerns. Physical blockers also tend to be thicker and more difficult to rub in.Ĭhemical formulas have a history of being more user-friendly since they are the easiest formula to apply and leave less of a white cast.
They also work immediately, and don't require any downtime before you can go in the sun (chemical sunscreens, meanwhile, take about 20 or 30 minutes to start working properly). Derms say mineral blocks tend to be less irritating for sensitive skin. If you see the ingredients titanium dioxide and zinc oxide, you're dealing with a physical sunblock.
COUPON FOR BULLFROG SUNSCREEN SKIN
Chemical sunscreens also often include antioxidants that disarm free radicals-which cause UV-ray-based harm-and cut down damage to your skin cells.Īside from the “sunscreen” and “sunblock” label, you can tell what type of protection you're getting by taking a peek at the ingredients label. “Sunblocks, or physical sunscreens, work by sitting on top of your skin to reflect UV rays, whereas chemical sunscreens sink into your skin to absorb UV rays and convert them into heat,” says Shereene Idriss, MD, a dermatologist in New York City. Although both protect your skin from the sun, the way they do that on a scientific level is very different. There are two types of sunscreen formulas: mineral (also known as physical blockers) and chemical. What’s the difference between chemical and physical sunscreen?
But before we get into our sunscreen reviews, here's everything you need to consider to find the best sunscreen for you.
We asked dermatologists to recommend the SPFs they swear by, then our editors put those formulas to the test to see which ones fit our extremely picky criteria. The good news is that the latest generation of formulas will change the way you feel about slathering it on. Add in the fact that the FDA is currently investigating the safety of common sunscreen ingredients (more on that below), and it makes the task of choosing an effective sunscreen that looks and feels good even more complicated. Sunscreen has a bad rap for being chalky, greasy, and generally all-around annoying. But finding the best sunscreen isn't easy-there's a reason people hate it. Ask any dermatologist: The fact that we need to wear sunscreen is not up for debate.
