The present invention relates to the devices of processing skin to use Athermal plasma. Have a skin interface electrode for during skin treating including electrode tip component, transformer, electric signal is converted into for changing high voltage low-voltage electric signal, electric signal generator receives the high voltage, and Athermal plasma is generated in the skin interface electrode, with a driving device, including a power supply, to generate the low-voltage electric signal. Electrode tip component and driving device include that collaboration elements are removably mounted on electrode tip component and driving device and by power electric connection to transformer.
