A skin rejuvenation device, the device comprising: a power supply adapted to generate a voltage and having at least two output terminals, said power supply providing a positive polarity between one of said at least two output terminals and ground and a negative polarity between another of said at least two terminals and ground; an applicator comprising an applicator head, wherein the applicator head comprises a plurality of spaced apart nodes, comprising a plurality of first nodes and a plurality of second nodes said first and second nodes adapted to come into contact with the skin to be treated, and a control adapted to selectively connect each of said nodes with one of said at least two output terminal of said power supply and to selectively allow each of said nodes to float with respect to said at least two output terminal, wherein said control is adapted to configure the first nodes as positive electrodes electrically coupled to the positive electrode power supply terminal or electrically isolated from the power supply, and wherein said control is adapted to configure the second nodes as negative electrodes electrically coupled to the negative electrode power supply terminal or electrically isolated from the power supply; and wherein the power supply delivers a current through the first nodes when the first nodes are configured as positive electrodes and current returns to the power supply through the second nodes when the second nodes are configured to be the negative electrodes, wherein no current is delivered to or from the skin when said control isolates said two nodes from the power supply to define a dissipation period during which current is dissipated through the skin. a power supply adapted to generate a voltage and having at least two output terminals, said power supply providing a positive polarity between one of said at least two output terminals and ground and a negative polarity between another of said at least two terminals and ground; an applicator comprising an applicator head, wherein the applicator head comprises a plurality of spaced apart nodes, comprising a plurality of first nodes and a plurality of second nodes said first and second nodes adapted to come into contact with the skin to be treated, and a control adapted to selectively connect each of said nodes with one of said at least two output terminal of said power supply and to selectively allow each of said nodes to float with respect to said at least two output terminal, wherein said control is adapted to configure the first nodes as positive electrodes electrically coupled to the positive electrode power supply terminal or electrically isolated from the power supply, and wherein said control is adapted to configure the second nodes as negative electrodes electrically coupled to the negative electrode power supply terminal or electrically isolated from the power supply; and wherein the power supply delivers a current through the first nodes when the first nodes are configured as positive electrodes and current returns to the power supply through the second nodes when the second nodes are configured to be the negative electrodes, wherein no current is delivered to or from the skin when said control isolates said two nodes from the power supply to define a dissipation period during which current is dissipated through the skin.
