Abstract: A skin measuring apparatus measures a skin moisture level using a voltage application electrode and a current detection electrode. The skin measuring apparatus includes an electrode driving module applying sinusoidal wave voltage to skin of a user through the voltage application electrode so that an amount of current is output from the skin through the current detection electrode, a signal detecting unit detecting the amount of current from the skin through the current detection electrode to calculate at least one of an impedance signal and an admittance signal, and a skin information determination unit analyzing the at least one of the impedance signal and the admittance signal to calculate the skin moisture level and a sweat production rate of the user, thereby analyzing the skin moisture level and the sweat generation rate more precisely without distortion.
