Zhong adheres to a stringent no-cruelty rule. There are no products or source components tested on animals, and we can prove it with our PETA accreditation! Except for voluntary humans, of course, we never test on animals, and we have always upheld cruelty-free standards since our inception. We only purchase from suppliers who do not test on animals, and both our production and testing procedures are totally free of animal experimentation.
