Book Description
The adverse effects of sunlight on the skin are well known, but only now is the scientific basis and rationale for treatment being evaluated. With the current level of interest from the general public and dermatologists in suntanning, sunburn and skin cancer, there is a great need for an authoritative, comprehensive review of the mechanisms, prevention and treatment of photodamage. There are only a handful of reputable clinical investigators who could put together an important volume and of this group, Dr. Gilchrest is probably the leading worker. She has collected all the latest information on photobiology, the effect of light on skin structure and function, clinical problems, prevention in adults and children, and medical and surgical treatment

Book Description
"Sun Protection in Man" looks at the beneficial and harmful effects of solar radiation. The physiological consequences of sun exposure have been systematically studied starting at the end of the nineteenth century and we now have accumulated knowledge about how Caucasian and Asian skins reacts to solar radiation. The chemical effects of solar ultraviolet radiation have been analyzed with particular emphasis during the second half of the twentieth century. Research on micro-organisms has allowed us to understand the mechanisms of UV-induced mutagenesis and photosensitization. Studies with laboratory rodents have opened the path to the understanding of UV-induced immune-depression, carcinogenesis, photo-damage and photo-aging. The results of these studies have enabled other scientists to investigate the same phenomena in human organs such as the skin and the eye. UV radiation damages hair, as well. The present knowledge in these fields is summarized in some of the chapters of this monograph.Mass phenomenon in Europe with the generalization of summer vacations which were a consequence of social reforms introducing the concept of "paid vacations". This created a need for protection and opened a market for sunscreens. This monograph is concerned with sun protection as a whole and is not just "another book on sunscreens". Nonetheless, in these days of general concern, it is important to learn about the efficiency of sunscreens. Several authors discuss how to reduce the number of impinging photons and explain why sunscreens seem to offer less protection than expected. Guidelines are given on how to use sunscreens in everyday life, which are expressed rigorously though clearly, for access to the common reader.Our knowledge on the relationship between sun and humans is at the early stages of development. Industrial and commercial activities are concerned by the development of this knowledge, and rules have been and will be promulgated to guarantee efficacy and safety of sun-products. It is hoped that this monograph will be of interest to the scholar, the layman and the legislator.

Book Description
As humans ventured into the twentieth century, the industrialized countries were confronted with the scourge of rickets. Although solariums were becoming common in the early 1900s and phototherapy was gaining popularity as a result of the awarding of a Nobel Prize to Finsen in 1903, it wasn't until 1921 when Hess and Unger demonstrated that rickets could be cured by exposure to sunlight that the healthful benefit of sun exposure appreciated. In 1941, Apperly (Cancer Research; 1: 191-195, 1941) noted that the occasional increased risk of skin cancer was associated with a decreased risk of many other more common and serious cancers. The alarming increase in the number of cases of skin cancer, especially melanoma, has caused great concern about the negative role of sunlight in health. The Sixth International Arnold Rikli Symposium on the Biologic Effects of Light was held in Boston, Massachusetts from June 16th - 18th, 2001. The goal of this Symposium was to focus on the very popular practice of tanning either by sunlight or by artificial light sources and the overall impact this practice has on health and disease. The program was organized by members of the Scientific Advisory Committee and my co-chair emeritus, Professor Ernst G. Jung. The Program Committee organized an outstanding state-of-the-art program that was enthusiastically received by the participants.
