The 17 Best Mineral Sunscreen 2021 That Won't Leave a White Cast - Glamour

Finding the best mineral sunscreen isn't the chore it once was. What were once gloppy, greasy, heavy creams guaranteed to leave a chalky white cast are now just as sophisticated as their chemical counterparts. A quick refresh: Sunscreens come in two forms—chemical, which are absorbed by your skin, and mineral or physical, which sit on your skin's surface (which is why they can be a little trickier to rub in). 

“Mineral sunscreen is a type of sunscreen that is formulated with the minerals zinc oxide or titanium oxide—or sometimes both—as the active ingredient that provides UV protection,” says Orit Markowitz, board-certified dermatologist and founder of OptiSkin in NYC. “The minerals sit on your skin's surface and act like microscopic mirrors to reflect harmful rays. In contrast, chemical sunscreens work by absorbing UV rays and convert them to heat, which is then released by the skin.”

While the best mineral sunscreen is whatever you will use every day, Markowitz recommends physical sunscreens for those with acne-prone or sensitive skin. Since mineral SPF doesn't get absorbed by your skin, it's less likely to clog pores and tends to be gentler on sensitive skin than chemical sunscreen. She also prefers mineral-based sunscreens since they are immediately effective against sun's rays, while most chemical sunscreens take about 20 to 30 minutes, and tend to need less reapplication.  

There's also recent concern over ingredients found in chemical sunscreens, and in May 2019 the FDA proposed new regulations for chemical sunscreens. 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. (More info on that here.) The FDA called for more research regarding the other 12, which are typically found in chemical sunscreens. If you're concerned about these ingredients, it's best to stick with mineral.

The good news is there are plenty of options out there for physical sunscreens that don't feel heavy or leave a white cast. These are the best mineral sunscreens to stock up on this summer.
