In the era in which human beings began seeking aesthesis, numerous options for scar treatments have been invented. Not all, but almost all of the useful treatment options are described in this book, along with the latest discoveries of scar pathogenesis. Combinations of these treatment options and the latest options of laser treatments are described with the help of a new scar classification system. This new scar classification system is based not only on the morphology and natural behaviour of scars, but also on the responses of scars to laser treatments. It is the editors hope that this book will illuminate the direction of future scar treatment research and provide a greater understanding of scar pathogenesis as well as practical guidance to more successful scar treatments.
