Abstract
Disclosed is an apparatus for controlling the output of a skin care device, which can reduce a peak power to be output to the skin, by suppressing a sudden current change when a direct current voltage is converted into an alternating current voltage. The disclosed apparatus for controlling the output of a skin care device: amplifies a direct current voltage and outputs same; converts the output direct current voltage into an alternating current voltage with a set frequency and outputs same to a pair of contact electrodes; and detects the skin current according to changes in the resistance of the skin to which the alternating current voltage is applied, so as to control the amplification of the direct current voltage.
