In the early 20th century, tanned skin was associated with good health. However, people began to protect themselves against potential overexposure to avoid sunburns. Around 1945, the first sunscreen products became available. In the years to follow, a vast number of different sunscreen filters and frameworks regulating filter substances and preparations, and methods characterizing sunscreen products were developed. The perception regarding the tasks of sunscreen products changed several times – initially it was promoted as a lifestyle product, then as a skin cancer preventive means, and more recently also for anti-aging. Different purposes and the widespread use of these products have led to myriad studies and a wealth of information. In this volume, the editors present a current collection of information analyzing and discussing issues related to sunscreen products and their use. These include challenges regarding the ideal sunscreen product including filter selection and formulation issues, measurement methods, performance characterization, safety, and regulatory issues. Further papers address topics related to the use of sunscreen products in everyday life, in vulnerable cohorts and outdoor workers. Controversial topics such as environmental effects of sunscreen products and the risks and benefits of UV radiation in the context of skin cancer, vitamin D and cardiovascular and metabolic health are also covered.

Our series Cancer Prevention - Cancer Control continues to address the causes and prevention of cancer. In this volume, Hill, Elwood, and English bring together a rich resource summarizing the state of science underpinning the primary prevention of skin cancer. While skin cancer causes an increasing burden, particularly in populations of European origin, our understanding of the role of sun exposure together with the genetic components of skin cancer continues to grow. Given the emphasis on evidence-based medicine and public health prevention efforts, it is noteworthy that, although we can all access the same evidence base, countries around the world have had remarkably different responses to the application of this knowledge to prevent skin cancer. The outstanding contribution of the Australian public health community to the scientific understanding of skin cancer etiology and the translation of this knowledge into national prevention efforts uniquely positions the editors to compile this volume focused on the primary prevention of skin cancer. In so doing they draw on an international team of authors to present a “state of the science” summary of skin cancer prevention and to identify those areas where uncertainty remains. To achieve successful prevention of cancer we must translate our scientific knowledge base into effective prevention programs. This book offers the reader keen insights into the depth of our understanding of etiologic pathways for skin cancer. This etiologic science base is complemented by rigorous prevention science placing emphasis on the social context for effective and sustained prevention efforts.

This document is a Call to Action to partners in prevention from various sectors across the nation to address skin cancer as a major public health problem. Many partners are essential to this effort, including federal, state, tribal, local, and territorial governments; members of the business, health care, and education sectors; community, nonprofit, and faith-based organizations; and individuals and families. The goal of this document is to increase awareness of skin cancer and to call for actions to reduce its risk.The first section describes the problem of skin cancer and its major risk factors. It also discusses the relationship between exposure to ultraviolet (UV) radiation and health. The second section describes the current evidence on preventing skin cancer, including current initiatives in the United States and in other countries. The third section describes the gaps in research related to skin cancer prevention, highlighting areas of research where more work is needed. The fourth section identifies specific opportunities to prevent skin cancer by reducing UV exposure in the U.S. population and calls for nationwide action.

The third edition is a comprehensive and updated overview of positive and negative effects of UV-exposure, with a focus on Vitamin D and skin cancer. Researchers, oncologists,and students will be provided with the most significant and timely information related to topics such as the epidemiology of skin cancer, the immune system and skin cancer, ultraviolet damage, DNA repair and Vitamin D in Nonmelanoma skin cancer and malignant melanoma. There have been a number of new, scientific findings in this fast moving field that necessitated a thoroughly updated and revised edition including new Vitamin D metabolites and skin cancer, new findings on the beneficial effects of UV and solar UV and skin cancer, adverse effects of sun protection and sunscreens, sun exposure and mortality, and more. The book will summarize essential, up-to-date information for every clinician or scientist interested in how to balance the positive and negative effects of UV‐exposure to minimize the risks of developing vitamin D deficiency and skin cancer.

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.
