1. A method for dermatological treatment of a patient body surface comprising:

  • positioning an active electrode surface in close proximity to a target site on the epidermis of the patient;

    directing an electrically conducting liquid along a fluid flow path past a return electrode surface to the target site to provide a current flow path between the target site and the return electrode; and

    applying high frequency voltage between the active electrode surface and the return electrode surface to impart sufficient energy into the target site to ablate several cells layers of the epidermis without causing substantial tissue necrosis beyond said several cell layers.
