For a long time, the received wisdom on skin types has been that there are four -- dry, oily, combination and sensitive. Dr Leslie Baumann, a top dermatologist, knows better. In fact there are 16 -- and each type benefits from different products and treatments. Dr Leslie offers her scientifically-based diagnosis to help you determine your skin type, then shows you how to best care for it. She gives answers to questions on whether or not you should use foaming products, or avoid exfoliation or Botox; guides you through the bewildering array of products and procedures to those that will best benefit your skin type (and along the way alerts you to those that would be a waste of money); gives advice on the best diet and health measures for your skin; and offers invaluable guidance on how to keep your skin looking young. With overviews of each skin type, simple questionnaires to determine your type, and illuminating case studies, this is the only guide you will ever need to determining your skin type and keeping your skin healthy and beautiful.
