In Korean culture, girls are taught at a young age the importance of protecting their skin. That's why you'll see so many women carrying umbrellas on sunny days, or why the sunscreen section in Korean pharmacies and grocery stores seems to contain more products than all the other beauty aisles combined. And these aren't your basic drugstore sunscreens. Featuring skin-specific formulas made with innovative ingredients and advanced beauty technologies, the options are literally endless, which is great news for anyone searching for the best Korean sunscreen for sensitive skin.
For a quick lesson, UVA and UVB rays are the two types of UV radiation that enter the atmosphere and contribute to skin damage on a daily basis, according to the Skin Cancer Foundation. UVA rays create the skin damage you don't immediately see, such as sun spots and skin cancer, while UVB rays show up in the form of sunburn. In the U.S., the SPF label only refers to your level of protection from UVB rays. While broad spectrum sunscreens provide coverage from both types of rays, they don't actually show how much UVA protection you're getting.
Korean sunscreens on the other hand, show exactly how much UVA coverage you get using PA signs (the amount of + signs indicate the level of UVA protection). According to K-beauty site Glow Recipe, PA++++ is the highest level of UVA protection on the market, so ideally — and this is especially important if you have sensitive skin — look for a sunscreen that has a rating of at least PA+++.
In addition to a high PA rating, sensitive skin types will want to look for a sunscreen that's free of common synthetic ingredients, like dyes and fragrance. And if you have skin prone to redness or irritation, a formula that contains soothing ingredients will be key (while acne-prone skin types stay away from oil, which will likely trigger a breakout). Mineral sunscreens, like zinc oxide and titanium dioxide, tend to be less irritating than chemical sunscreens, though you can find some great exceptions to the rule, especially in the case of Korean beauty.
