SUNSCREEN in UV

These two are either poor researches or purposely excluding information about the ZnO and that it is likely ZnO NP that gets into the bloo. d and not organic (naturally occurring) or non-NP ZnO. And to state those that use caution when using synthes! zed ch.em¡cals on, in, or around our bodies are strictly doing so because of the word "chem.¡cal" is another example of what poor arguments these two have... Yes, it's all che.m¡cals. Our bodies are che.m¡cal processing wonders. The problem is our bodies have evolved to be able to process most/many of the c.hem!cals in nature that we would naturally come in contact with. Our bodies have not evolved to process many of the lab created or synthes! zed ch.em!cals. Which is why a man-made c.hem!cal is often deemed safe, sometimes for decades. Before we realize how harmful it is.
