Japanese Sunscreens

So recently I found out that the FDA in the United States hasnt approved some of the ingredients available in Europe and Asia, so I decided to pick up some sunscreens. I wasnt sure what some of the ingredients were, so I bought a bunch of different brands.

Unfortunately for me, I should have looked up the words for titanium dioxide and zinc oxide. Most of the brands I bought have those two ingredients. I have no idea if theyre nanoparticles or not.
