Sunscreen Ingredient Decoder: Which INCI Names Are UV Filters?
Paste the ingredient list off a bottle and see which entries are UV filters, which part of the UV spectrum they cover between them, and the maximum concentration each regulator permits.

The data behind them

The decoder reads filters.json, the filter database published on the data page under CC BY 4.0. Every regulatory figure in it carries the document it was read from and the date it was read; a figure we could not confirm in a primary source is published as null, never as a guess.
