I respectfully disagree with L'Oreal I agree they may find the most effective ingredients, a lot of their products are irritating and some of the ingredients push the limits of what's safe. And I assume they're the rebels of the EU.
I don't know about the Japanese companies, or what they sell. My guess is they're pretty solid as far as cosmetics is concerned. Maybe. If it's anything like their Ideals in testing in medicine. Shiseido sounds vaguely familiar, isn't it that the company using dermal stem cell research in their cosmetics. If so... *googles* OMG YUS!! I LOVERS THESE GUYS! Yep, I'm waving my flag on board team Japan. *rubs my gut and whispers* "the feelings you give me are never wrong, but often lead to gas."
And I am pretty certain I have no random insight to the Brazilian company.
Idk, the Japanese has gotten their research in pretty much all fields together. Why can't we?
