Don't Go to the Cosmetics Counter Without Me, Paula Begoun

I cheat and go to Chapters and read the book on the shelf. But---I don't buy a single product without checking it in this book first!

This book reviews almost every brand and product out there. What's in it, whether it is good for the skin, and how the product performs.

There is a more up-to-date version that you pay a membership for online.

Because I have dry skin, and most foundations are made to mattify skin, I had huge problems finding a foundation to actually not make my skin flake off. This book saved me. It's my Holy Grail!
