I think that there is a lot of good information in the book. It might make a good starting place for make-up consumers. For better skincare advice, see a dermatologist. Cosmetics, by definition, cannot permanently alter your skin. Things that do that are classified as drugs and are regulated. I have met very helpful and informed cosmetics counter people and used to be one. While I admit there are people who just want you to spend your money on products you don't need, I managed to become the top seller at my counter by only selling people the products I thought would benefit them. If you aren't happy with the person helping you, get someone else. The woman writing this book sounds angry, and I have a hard time swallowing advice from an obviously biased person. But, I can sympathize with her frustration. And she's definately hit a nerve with a big portion of the country. Good luck, everyone!
