PROBLEM TO BE SOLVED: To provide a control device capable of efficiently permeating a beauty ingredient of cosmetics into the skin, and a beauty device including the control device. A beauty device includes a first electrode 110, a second electrode 120, and a control device. The first electrode 110 and the second electrode 120 form an electric field inside the skin so as to form a path through which cosmetic ingredients of cosmetics permeate. The control device includes a voltage control unit that periodically applies a DC pulse voltage having a potential higher than that of the second electrode 120 to the first electrode 110 and sets the duty ratio of the DC pulse voltage to more than 50% and 85% or less.
