The Beauty Bible, Paula Begoun

This book changed my skin. It is a complete break down of what is good and bad in the beauty products we use.
Scientific proof of what works and doesn't work, all with out having to read all the journals. This book opened my eyes wide to the makeup industry. I leave it by my bed and read it now and then just to remind myself.

It is avail at Chapters and Amazon, but I got it for free with an order I placed online. The author has a skin care line, that only uses ingredients that are safe for the skin. She also has another book, which rates other products based on their ingredients and user testing.
