This book was written to assist the dermatologists and practitioners in the management of rare and challenging skin disorders. It is the most valuable collection of such skin disorders from more than 274 outstanding contributors over 4 decades in China. In this book, a comprehensive coverage of about 387 conditions are illustrated by 1215 superb images, and each is introduced with an initial summary of clinical characters. This atlas incorporates a wide range of skin disorders from the mildest and common conditions to the most severe conditions. The objective of this book is to provide readers with a clinical reference, which can be easily approachable and possesses the necessary expertise to sharpen a dermatologist’s diagnostic and clinical acumen.

Health Challenged Skin: The Estheticians Desk Reference is designed to address the lack of esthetic knowledge in the area of skin diseases. It covers an incredible range of diseases and disorders in terms of examining how they manifest symptomatically on the skin, and it is organized to offer easy-to-find, hands-on application for daily use.

With about 10–20% of the adult population in Europe being tattooed, there is a strong demand for publications discussing the various issues related to tattooed skin and health. Until now, only a few scientific studies on tattooing have been published. This book discusses different aspects of the various medical risks associated with tattoos, such as allergic reactions from red tattoos, papulo-nodular reactions from black tattoos as well as technical and psycho-social complications, in addition to bacterial and viral infections. Further sections are dedicated to the composition of tattoo inks, and a case is made for the urgent introduction of national and international regulations. Distinguished authors, all specialists in their particular fields, have contributed to this publication which provides a comprehensive view of the health implications associated with tattooing. The book covers a broad range of topics that will be of interest to clinicians and nursing staff, toxicologists and regulators as well as laser surgeons who often face the challenge of having to remove tattoos, professional tattooists and producers of tattoo ink.

While the American health care system has consistently been criticized for its noticeable detriments, few have taken the time to recognize the significant benefits and potential of this system. But with Skin in the Game, authors John Hammergren and Phil Harkins provide a comprehensive overview of the history of our health care system, an explanation of its current state, and a picture of the great strides that they see being made in the near future.

The concept of expressing acidity as the negative logarithm of the hydrogen ion concentration was defined and termed pH in the beginning of the 20th century. The general usefulness of the pH concept for life science was recognized and later gained importance to analytical research. Reports on results of pH measurements from living skin established the term acid mantle - the skin's own protective shield that maintains a naturally acid pH. It is invisible to the eye but crucial to the overall wellbeing of skin. Chronic alkalization can throw this acid mantle out of balance, leading to inflammation, dermatitis, and atopic skin diseases. It is therefore no surprise, that skin pH shifts have been observed in various skin pathologies. It is also obvious that the pH in topically applied preparations may play an important role. Optimal pH and buffer capacity within topical preparations not only support stability of active ingredients and auxiliary materials, but may also increase absorption of the non-ionized species of an acidic or a basic active ingredient. They may even open up opportunities to modify and "correct" skin pH and hence accelerate barrier recovery and maintain or enhance barrier integrity. Further efforts are needed to standardize and improve pH measurements in biological media or pharmaceutical/cosmetic vehicles to increase and ensure quality, comparability, and relevance of research data. In this volume, we present a unique collection of papers that address past, present and future issues of the pH of healthy and diseased skin. It is hoped that this collection will foster future efforts in clinical and experimental skin research.

This is a perspective on the chemical world we live in and why I believe all of us should be concerned for our lives, the lives of our families, friends and the animals that share our lives. It is not intended to scare you, although it might. It is really to draw attention to what our lives have become and the chemicals, companies and products that rule it. Our skin is our largest and most vulnerable organ. Love it and it will love you. Protect it and it will protect you. Abuse it and it will shorten your life.There have been more chemicals developed in the last twenty years than in all of mankind. Of the thousands of chemicals in use in the cosmetic, personal care and household products industry, less than 1% have been tested for safety. A few years ago I read that ~63% of American claim to have a skin disorder. Connection? Probably! There are no US Government regulations for skin care or household products.What I have come to believe is that more than 50% of skin disorders are misdiagnosed and are caused by chemicals in the products we use every day.
