Begoun also lists which companies are cruelty-free and which continue to conduct animal testing. The majority of the book--and that's nearly 800 pages--is devoted to reviews of thousands of cosmetics, from cleansers, foundations, alpha-hydroxy acids, and moisturizers to lip liners, eye shadows, and concealers, all of which Begoun has personally tested. (There are no hair care products listed, as that warrants another book entirely: Don't Go Shopping for Hair Care Products Without Me.)

She's perfectly frank and tells it like it is. (On Revlon's ColorStay Makeup: "goes far beyond the claim of 'It won't come off on him.' It won't come off when you want it to.") You'll learn how to tell when you're being boondoggled by a salesperson, what's overpriced and overhyped, as well as what's overlooked. More than 200 brands are included, along with a helpful summary at the end that lists the best products for each cosmetic category. It should be noted that not only is Begoun a fine consumer advocate, she's also a self-esteem advocate: she mentions time and again that even the best cosmetics won't necessarily improve your life, and that's a point well taken.
