1. A hand-held device for electrically powered skin treatment, comprising:

  • a first outer electrode (7) which is adapted to be in contact with a hand of a user when the device is held in the hand of the user for use;

    a second outer electrode (20) which is adapted to be placed on an area of skin to be treated;

    an electrical energy source, wherein poles of the electrical energy source are electrically connected to the first and the second electrodes (7, 20) during operation of the device;

    an electrically operated vibrator (15);

    a base (2), wherein the first outer electrode (7) is provided on the base (2);

    a cap (3, 9) detachably placed on the base (2), wherein the cap forms the second outer electrode (20);

    wherein the electrical energy source is arranged in the base (2);

    wherein the electrically operated vibrator (15) is fixed in or on the cap (3, 9) and is adapted to vibrate a part of the device located on the area of the skin to be treated so that, during operation, the device produces an intensified massaging effect on the skin to be treated, whereby skin pores are widened;

    wherein a first and a second electrical contact are provided between the base (2) and the cap (3, 9), both electrical contacts comprising a base contact element and a cap contact element, the base contact element being arranged in the base (2) and the cap contact element being arranged in the cap (3) in such a way that the contacts are closed when the cap (3) is placed on the base (2), the electrical connection between the energy source and the second electrode (20) being produced by the first contact, and the electric circuit, which supplies power to the vibrator (15), running through the first and second contacts.
