Most women, according to the author, a biologist, are ""dermal hypochondriacs,"" sold on -- along with all those brightly colored tubes and pots -- the notion of ""dry skin,"" or at the very least that salon-inspired catchall ""combination skin"" -- when chances are your epidermis is actually balanced (or can be again once you stop those facial exercises, turtle and queen bee preparations), even if you do tend toward dryness or oiliness and produce a pimple or two from time to time. Chase is no debunker of cosmetics as such -- there are many that really do what the ads suggest, that help make you more attractive, that compensate for environmental conditions. In short, products that work. Chase names them, analyzes ingredients, sets out regimens; she discusses the benefits of cosmetic surgery; the advantages (especially for older women) of coloring your hair; and she throws in just enough chemistry to support her arguments. A knowledgeable and convincing book that will make those creams and lotions as profitable to you as to Revlon.
