| 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. | A weak UVB filter that earns its place mainly by dissolving stronger ones — a lot of sunscreen chemistry is really solvent chemistry. Ten percent was the traditional ceiling; the EU has since lowered the level allowed in facial products after reviewing it. If you are pregnant and would rather avoid it, mineral or newer-filter sunscreens are easy alternatives. Ask your doctor. |
