Not solely that, however Korean sunscreens use the PA score system, which measures safety from UVA rays. “The PA system ranges from PA+ to PA+++, with PA+++ being the best stage of UVA safety,” says Dr. Chang. The U.S. doesn’t have a standardized system like this for UVA safety, however as a substitute buckets it below the time period “broad-spectrum” to point protection in opposition to UVA and UVB rays; the precise stage of protection this presents is unclear.
What to search for in a Korean sunscreen
SPF Stage
Sunscreen safety issue, or SPF, is identical in Korea as it’s stateside. Nevertheless, “within the US, SPF can vary from 15 to 100—and particular safety elements are usually labeled,” says Dr. Chang. In the meantime, in Korea, these rankings typically transcend SPF 50, though manufacturers don’t all the time share the precise quantity; quite, their SPF is marked as 50+. (Needless to say the American Academy of Dermatology recommends a minimal of SPF 30, so this shouldn’t be trigger for alarm.)
Chemical versus mineral filters
Chemical filters sink into pores and skin, the place they convert UV vitality into warmth, which ultimately dissipates from pores and skin. “Nearly all of Korean sunscreens are chemical sunscreens, and so they’re protected and efficient,” says Dr. Kim. They lend themselves to Korean sunscreens’ famously weightless texture and invisible, residue-free end.
In the meantime, bodily, or mineral, filters stay on the floor on the pores and skin, the place they “have the flexibility to mirror and bodily block the UV rays,” says Dr. Kim. He prefers these for hyperpigmentation and for his sufferers who’re pregnant, breastfeeding, or present process fertility therapies, as they’re not absorbed by pores and skin.
Texture
There’s barely much less variation in texture amongst Korean sunscreens, partly as a result of all of them handle to really feel weightless and ethereal on pores and skin. Nevertheless, they do have some variations, and it’s value taking your pores and skin sort under consideration. “Some textures are extra hydrating, in order that they’re extra suited to individuals with dry pores and skin,” says Dr. Kim. For these with oily or acne-prone pores and skin, think about extra light-weight gel or serum-like choices, which might sink in rapidly.
