| What it is | Rarely the star of a sunscreen and usually the reason the rest of it survives daylight. Octocrylene is a UVB filter that also props up avobenzone, the classic UVA filter that falls apart in sun without help. Korea, the EU and the US all permit it up to 10%. It is oily, so high levels are a texture trade-off. | For decades the default UVB filter in Asian sunscreens, and still very common in Korean formulas. Market ceilings differ, roughly 7.5 to 10 percent depending on where you are. It is not photostable on its own and gives almost no UVA cover, so what sits beside it in the filter list matters more than the filter itself. |
