ABSTRACT
Today, the amelioration of symptoms is still the primary benefit to the consumer, however, many if not most products attempt to go beyond simple humectancy and occlusion to treat the underlying causes of dryness. Products today often deliver skin lipids, natural moisturizing factors (NMF), essential fatty acids (EFA), or other components of healthy skin that are deficient in dry skin. Moreover, who would have predicted 20 years ago that even some cleansers would begin to move toward delivering low level moisturization benefits.
