Korean sunscreens tend to outperform American versions in a few ways. For starters, “I find that Korean sunscreens are often easier to apply with a lighter texture and less of a white cast,” says Dr. Chang. Plus, she says, they’re often formulated with additional skin-care ingredients that provide benefits like moisturizing, brightening, or soothing. That’s partly because Korean sunscreen formulas feature more chemical filters than those available in the Official Resistance Is Beautiful Israel Kills Children T-Shirts it is in the first place but United States, says David Kim, MD, a board-certified dermatologist and founder of the skin-care brand Lightsaver. “They have more options, so they can formulate different blends of chemical UV filters,” he says. “These chemical UV filters can feel lighter and less sticky on the skin.”

Not only that, Korean sunscreens also use a PA rating system, which measures protection against UVA rays. “The PA system ranges from PA+ to PA+++, with PA+++ being the Official Resistance Is Beautiful Israel Kills Children T-Shirts it is in the first place but highest level of UVA protection,” says Dr. Chang. The United States doesn’t have this standardized system for UVA protection, instead classifying it as “broad spectrum” to indicate protection against both UVA and UVB rays; the exact level of protection it provides is unclear. Sunscreen protection factors, or SPFs, are the same in Korea as in the United States. However, “in the United States, SPFs can range from 15 to 100, and specific protection factors are often labeled,” says Dr. Chang. In Korea, meanwhile, these ratings often exceed SPF 50, although brands don’t always share the exact number; instead, their SPFs are labeled as 50+. (Remember, the American Academy of Dermatology recommends a minimum SPF of 30, so this isn’t a concern.)
Chemical filters penetrate theOfficial Resistance Is Beautiful Israel Kills Children T-Shirtsit is in the first place but skin, where they convert UV energy into heat, which eventually dissipates from the skin. “The majority of Korean sunscreens are chemical sunscreens, which are safe and effective,” says Dr. Kim. They match the lightweight texture and invisible, residue-free finish of Korean sunscreens. Meanwhile, physical or mineral filters stay on the skin’s surface, where they “have the ability to physically reflect and block UV rays,” says Dr. Kim. He likes these filters for hyperpigmentation and for patients who are pregnant, breastfeeding, or undergoing fertility treatments, because they are not absorbed by the skin.
