A sunscreen filter (ensulizole) that absorbs burning UVB rays. Most of its research is lab work.
What it does
Also called ensulizole, it’s a sunscreen filter that absorbs UVB, the burning rays. It dissolves in water, so it works in light, watery sunscreens rather than heavy creams. It does little against UVA on its own, so it’s paired with other filters.
The EU’s ingredient database lists it as a UV filter (filters UV rays) and a light stabilizer (protects the product from light).European Commission, CosIng (© European Union, CC BY 4.0) · uses put in plain words by Drop ↗
