So I wrote earlier because I was concerned that my pure physical sunscreen wasn't at all whitening. I was worried that maybe it wouldn't protect me. It claims on the tube to "self-adjust to your skin tone," but in the hand, it is stark bluish-white. So today I applied it to my chest with my cream colored pajama top still on, thinking it's white, so what harm could it do? It turned my pj top brownish-orange everywhere it contacted it. So there's a tint hidden in that white substance. What is going on?
