Nanoparticles/ texture of sunscreen
I've read that particle size matters in suncreen, and that the bigger the particles of micronized zinc oxide or titanium oxide the better. This often results in a sunscreen that takes a lot of rubbing in order to fully dissolve into the skin. I noticed this product, conversely, is easily absorbed and has a nice texture.
My question concerns the use of nanoparticles of titanium dioxide. I know scientists are concerned about nanoparticles and their effects. Because this product is so easily absorbed, I suspect that the titanium dioxide may have been reduced in size. Is that why the product has its silky texture?
