ABSTRACT
Facial moisturizers are some of the most important over-thecounter skin care products. Dramatic changes are induced in the skin through the addition or removal of water. A wellhydrated facial skin is soft, smooth, and beautiful while a poorly hydrated facial skin is rough, harsh, and unattractive ( Fig. 3.1 ). The main effect produced by most cosmeceuticalsthat are designed to minimize the appearance of wrinkles is excellent skin hydration. Conditions ranging from facial wrinkles of dehydration to facial eczema are treated by moisturization.
