Dry skin is characterized by a lack of moisture in the outer layer of the skin and can occur as a result of numerous factors including cold weather, low humidity, age, etc. In this study, the moisturizing benefits of two formulas were evaluated for barrier function improvement/impact when used by women with moderately to severely dry skin on their lower legs.

Skin hydration of the lower legs was measured with two different instruments: 1) a Corneometer, which measures hydration in arbitrary units from 0 to 120, with higher values indicating more hydrated skin, and 2) Skicon, which measures hydration in microSiemens (uS) from 0 to 2000, with higher values indicating more hydrated skin. Five measurements were taken with each instrument.
