Yes I have and I have a kind of in the middle stance. Studying cosmetic chemistry and the building blocks of skincells really helped me. If you can read an inky list and know what the ingredients are/where they come from/what they do, then you start to see that there are unnecessary/irritating ingredients in both standard and natural brands. 

Where I agree with you the most, is the simplicity of the ingredient list. A product with 50+ingredients is always a red flag. 

 I also found it interesting the “loophole” the fda has for the cosmetic/fragrance ingredients where they don’t even have to list it! ( that’s pretty disturbing)
