Whether or not Light Elegance manufacture and formulate their own formulas is to be determined. And so they are on my to watch list. The only brand not on my to watch list is, of course, CND. Its very hard to get off this to watch list btw. Simply because manufacturer must prove without a doubt that their products pass basic requirements. Its actually not my job to prove this.
It is simply not enough when it states on their website or product packaging that they make their own stuff. Of course, you can personally go by that. I wouldn't. Because, as you've mentioned, facts are always a good thing to have
But "facts" are not enough. It must be proven to be true several different ways.
