Skin, Hair, and Nails - Potential trouble spots

All of us are very conscious of the condition of our skin and worry when something seems to be wrong with it. The temptations to worry too much, to overtreat, to take the advice of a well-meaning friend, to use the wrong (but heavily advertised) product are very great. Knowing about the properties of the skin and what medical knowledge has to say about skin problems can help to avoid mistakes in caring for it. See Ch. 21, Skin and Hair .
