That product description sounded to me like a mechanical (not chemical) sunscreen. Unlinke chemical sunscreens those tend to have a visible whitening effect when applied properly. Given that the Choice tests were blind and on human skin, I can imagine a scenario where it was “rubbed in” like chemical sunscreen until invisible, and gave the absurdly low score as a genuine result of misapplication

On the other hand, two independent labs getting similar awful results is damning.

It’s unfortunate the responses from these companies are mostly along the lines of “nuh-uh”. It’s good that there have been some emergency retests, but I would have hoped that someone would have worked with Choice to figure out what was up rather than just telling them “you did it wrong”.
