This product contains UV filters. Which filters are permitted, and at what concentration, differs between markets.

UV filters are among the most tightly regulated cosmetic ingredients, and the permitted set differs between the EU, the US and elsewhere.
What the rules say

What it sets out
Maximum 25 % w/w as a UV filter. Packs don't print concentrations and we hold none, so no page here measures a product against it.
Separate conditions apply to nano forms and to use in products that could be inhaled.
What we don't know
- Where it comes from — plant, mineral, synthetic — isn't recorded.
- How much of it is used in any particular product. We hold no concentrations at all.
