PURPOSE: A method and apparatus for controlling the power of a skin care device, and a portable skin care device using the same are provided to gradually increase power when a voltage increases and gradually decrease power when a voltage decreases by a software method without using a DC-DC converter. CONSTITUTION: The method comprises the steps of: (a) investigating if a PWM control is operated at a desired set value (S2) if a pulse width check program(PWM_CHECK) is started (S1); (b) returning to continue if operated at a desired set value('PWM OK FLAG'=1), or comparing a PWM set value('PWM_TARGET) and a PWM actual value('PWM_PUF') being applied if not (S3); and (c) returning to continue if the set value and the actual value are the same('PWM_PUF'-'PWM_TARGET'=0), or executing the PWM control step if not.
