And, believe us, you will have to be fearful about each.
“UVA rays penetrate even more deeply and are responsible for most skin aging, hyperpigmentation, damage to collagen fibers, and more aggressive skin cancers including melanomas,” Dr. Ciraldo notes.

What about Korean sunscreens?
Consistent with Lam-Phaure, South Korean sunscreen formulation are advancing at a fevered clip in comparison to the U.S. “The FDA considers sunscreens over-the-counter drugs, so formulators are limited with what ingredients they can use,” Lam-Phaure tells Attract. “The addition of any new active ingredients to the Title 21 Monograph, which regulates these drugs, would require extensive testing,” she provides. But Asian sunscreen formulators now have filters like Tinosorb at their disposal, which delivers a double-whammy via protective towards each UVA and UVB rays. “In fact, the last time the FDA made any decisions regarding sunscreens was in the 1970s,” says Lam-Phaure. “It’s unlikely that’ll we see new approved UV filters any time soon due to a lack of FDA funding for the cosmetics sector, as well as a lack of data,” she notes.
