How do you find out who makes what brand? For example, Lancome makes Loreal.?

If you're looking for a particular brand's "parent company" that info should be available on their site. Or it could work in the reverse, like find out other companies under one company. The links to this stuff is usually at the bottom of the page, like "Companies" or "About [company]"|||you can just check it up on the products' packaging. for example, on a Za packaging you can most probably see imported by Shiseido Co (pte) Ltd and on a Fasio packaging you can see imported by Kose and so on...
