Abstract
A method of measuring skin moisture content, the method including: measuring a differential rate of a skin impedance of a predetermined skin area of a user for a predetermined period of time; and determining that the skin area is a moist area when the differential rate of skin impedance is greater than or equal to a predetermined value for a predetermined period of time, and determining that the skin area is a dry area when the differential rate of skin impedance is less than the predetermined value for the predetermined period of time.
