Everything you always wanted to know about skin: layers, nails, hair, basic care (don't wash too much), life changes (birthmarks to liver spots), and common problems. The three author-doctors stick to the facts--no gimmicks, no self-promotion, no dumb jokes--in short chapters that consider the symptoms and treatments of dandruff, corns, warts, poison ivy, herpes, and lice. And they toss in a few intriguing incidentals for variety: ""The mite Sarcoptes scabiei [scabies] is responsible for 'the seven-year itch' that has plagued countless thousands. . . throughout history."" A reliable, descriptive summary.
