The present invention involves a beauty apparatus having a first electrode and a second electrode configured to enable conduction via the human body, said beauty apparatus allowing a cosmetic ingredient, which has been electrically charged by passing a current through an external circuit constituted by the first electrode, the second electrode and the human body, to be infused into the skin. The beauty apparatus has: a body provided with the first electrode and the second electrode； and a control unit that is disposed inside the body, connects the first electrode and the second electrode, and controls the current that flows therebetween. The control unit is configured so as to execute an iontophoresis mode in which the following are sequentially repeated: an iontophoresis step in which current (F1) with one polarity passes between the first electrode and the second electrode； a reset pulse step in which a pulse current (F2) of another polarity passes between the first electrode and the second electrode； and a skin care step in which a current (F3), wherein the polarity alternately switches places, passes between the first electrode and the second electrode.一種美容器具，係構成第1電極與第2電極可經由人體導通，讓電流流到第1電極與第2電極與人體構成的外部電路，藉此讓帶電荷的美容成分滲透到肌膚內部用的美容器具。美容器具是具有：具備第1電極與第2電極的本體部；以及被配置在該本體部內，並且連接於第1電極與第2電極，控制在該等之間流動的電流的控制部。控制部是構成依序反覆執行讓一方極性的電流(F1)流到第1電極與第2電極之間的離子導入步驟、讓另一方極性的脈衝電流(F2)流到第1電極與第2電極之間的重設脈衝步驟、以及讓極性交替轉換的電流(F3)流到第1電極與第2電極之間的護膚步驟的離子導入模式。
