BOOK REVIEWS 363 SKIN AGING HANDBOOK, Nava Dayan, Ed. (William Andrew Publishing, 2008), 494 pp. This refreshing book takes a new look at aging skin. The editor, Nava Dayan, brings together knowledge from many different disciplines, including dermatology, sociol- ogy, cosmetic formulation, gerontology, and biochemistry, to deliver a compelling treatise on how skin ages and what can be done from a topical standpoint to positively affect appearance. The text begins with a chapter on aging skin from a sociocultural perspective. As a physician, I found the concept of medical- ization intriguing. Medicalization is the formalization of bodily states and practices that were once handled informally. For ex- ample, aging now has been formalized as a disease requiring medical intervention. Maturity is termed the “third age,” repre- senting the time from retirement to the onset of terminal decline. This shift re- quires medical attention to maintain peak health with advancing age and creates op- portunities for the skin care industry to de- velop products to optimize appearance, the topic of the second chapter. The next interesting chapter, by Andreas Lanitis, is a fascinating look at the world of computer-based aging progression meth- odologies, describing how childhood im- ages are modifi ed to create a picture of the mature face. It is a study in changing facial proportions, accounted for by loss of bone, redistribution of fat, and skin texture ab- normalities. With this introduction, the book launches into Part 2, discussing the biochemical, pharmacological, and ethnicity aspects of aging. Different aspects of aging, including skin barrier anomalies, sebum and epidermal lipid changes, infl ammation, cell senescence, and topical methods of treat- ing skin aging, are discussed. This information is a nice preface for the core of the book, dealing with product de- velopment (Part 3), testing methodologies (Part 4), and regulatory aspects (Part 5). The formulator will fi nd this book indis- pensable as it brings together an under- standing of the aging process and how products should be formulated and tested to meet the needs of the expanding geriat- ric population. Not all skin is the same. Failure to address the needs of mature indi- viduals is a missed opportunity. This text provides the necessary knowledge to allow the formulator to seize this opportunity.— ZOE DIANA DRAELOS—Dermatology Consulting Services.
