Skin xerosis. Clinical report on the effect of a moisturizing soap bar.

Two double-blind and supervised clinical studies were conducted to determine the direct effect of a moisturizing soap bar on skin xerosis (dry skin). One study compared the moisturizing soap bar with a commercially available soap bar and used young adult subjects who resided in an area of high relative humidity. The second study compared the moisturizing soap bar with a placebo soap bar and used elderly subjects who resided in an area of low relative humidity. In both instnaces, washing twice daily with the moisturizing soap bar provided a lower level of skin flaking than the particular soap bar with which it was compared.
