1. A non-invasive system for delivering a liquid onto a depth of a dermis under a stratum corneum via pores of a human'"'"'s skin, the system comprising:

  • a storage container for containing said liquid;

    a pumping unit coupled to the storage container for increasing a pressure of said liquid;

    a suction mechanism configured to generate a negative pressure, said suction mechanism comprising;

    a separation container for providing liquid separation of a liquid-gas mixture;

    a compressor;

    a gas ejector connected to said compressor;

    a connecting tube between said separation container and said gas ejector;

    an operating handpiece comprising;

    a motor;

    a rotary drive coupled said motor;

    a tip rotatably coupled to said rotary drive, said tip comprising;

    an open chamber, andan external channel;

    an outer casing accommodating said motor and said rotary drive, and further including;

    at least one suction port for applying negative pressure inside said open chamber, andat least one supply port for supplying said liquid into said external channel under pressure from said pumping unit;

    a power source having a first terminal and a second terminal of opposite charges;

    an electrode connected to the first terminal of said power source and being configured for being brought into contact with the human skin during a delivery; and

    an electrical connection between said second terminal of said power source and the liquid within the external channel of the handpiece;

    wherein the tip of said operating handpiece comprises at least one nozzle for delivery of the liquid from said external channel directly into a pore of the human skin drawn into the open chamber; and

    wherein said nozzle comprises an outlet having a diameter smaller than an opening of said pore such that said nozzle delivers a stream having a cross-section smaller than an inlet of said pore, such that the liquid in electrical contact with the second terminal of the power source completes an electric circuit through the skin to the electrode connected to the first terminal of the power source.
