You walk into the drugstore and there they are. A sea of paints, powders, polishes, and shampoos luring you with promises of romance, popularity, and beauty. Statistics say 90% of you use lipstick, 85% of you use blush, and 80% use mascara. Advertisers just about guarantee that if you use their creams, lotions, and dyes, you'll lead a more radiant, successful life. What all those supermodels tend to obscure is the fact that not all of these products are created equal, or are appropriate for everyone.
