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.
进行了两项双盲且有监督的临床研究，以确定一款保湿肥皂对皮肤干燥症（干性皮肤）的直接效果。一项研究将该保湿肥皂与一款市售肥皂进行比较，并使用居住在相对湿度较高地区的年轻成年受试者。第二项研究将该保湿肥皂与一款安慰剂肥皂进行比较，并使用居住在相对湿度较低地区的老年受试者。在这两项研究中，每天用该保湿肥皂清洗两次，与所比较的特定肥皂相比，皮肤剥落程度更低。
