I've heard about it, but also Garnier failed this test and we have to mention - the products that failed were two sunscreens for kids. You can find more about this issue on
which.co.uk I checked the website and it's like a consumer association, the thing is that they didn't mention the lab - while Purito tests were made in Poland and Germany, they tested in one lab from what I figured out so I would suspect that they might not get fully accurate information. And yes, they say they are independent, but it's not like you can base all informations on one research - lots of labs right now have long queue since Kbeauty (and not only Kbeauty) brands started to test their sunscreens in few labs instead of using just one lab. So I would be neutral if it comes to this. We also don't know if this is an issue only for UK or EU and other countries too since ingredients can be different for each country.
