Stanford-trained, Bay Area dermatologists Rodan and Fields have demonstrated their over-the-counter acne-treatment products to mass audiences on television, and their telegenic charm carries over into this chatty but deeply knowledgeable and practical book. In defining what acne is (technically, a disease that makes use of bacteria), Rodan and Fields discuss their own skin histories, their families, their friendship and their professional beginnings:""So there we were in 1987, the only women in our practices (all our other colleagues were men), and the women patients flocked to us because we understood what they were going through. Plus we love makeup and skin-care products and pampering and we'd never tell our patients to stop wearing their makeup or stop going for facials if it made them feel better."" They worked years on a""spot-kill"" product that worked pimple-by-pimple, before realizing that""by treating the full face daily, continuously, with a combination of medications, acne can be stopped at the source."" The rest of the book explains their Proactive Solution and Multi-Med Therapy regimens, and maps them onto various demographics, skin-types and problem areas, from""Babies and Children"" to""Perimenopausal and Menopausal Women."" They are careful to take""Acne's Psychological Aftermath"" into account, and offer glossaries of product ingredients and technical terms. Annoying testimonials feel spliced in, but Rodan and Fields write with intelligence and care, and push their products in the clear belief that they work.
