Highlighting functional changes in the structure of the epidermis and the stratum corneum, this book presents overviews of clinical and consumer testing approaches together with ex vivo evaluation procedures. It covers key aspects of personal moisturizing and washing products, such as efficacy and formulation of moisturizing ingredients, safety and regulatory guidelines involved in the formation of skin-improving technologies, development of new products, and effects of consumer testing approaches. The book explores the science behind formulating a moisturizer and uses it to the criteria for evaluating and recommending moisturizers.
