This book deals exclusively with the former form of treatment. Prof. Howard Maibach and co-workers are to be congratulated for sharing all their dermatological insights with the readers of Cosmetics & Toiletries Magazine for at least a decade or so. We should accepts these lessons in dermatology with thanks and use them in our strive for ever better products. After all, our goal is to avoid creating a product that might lead to problematic skin. To assess whether we were successful in these endeavors, cosmetic product developers often unknowingly use dermatological techniques to demonstrate the safety of their products. Because of the nature of our industry, we need to develop our cosmetic products faster and faster, so it is more than fantastic that Prof. Howard Maibach and colleagues share their latest insights with us in a series of very effective reviews. I just hope that we will all have the time to read and digest the content of this book for the benefit of all, dermatologists, cosmetic product developers and consumers. After all, we all want only the same: better cosmetic products. Reading this book is the very first step to achieving it. --Prof. Johann W.
