1. A system for selectively cauterizing skin pores comprising:
- a probe having a conductive central needle adapted for insertion into a patient'"'"'s skin pore and a conductive outer sleeve portion adapted to be handheld by an operator who is in electrical contact with the patient;
an electrical power source for producing shortwave electrical energy suitable for skin cauterization;
low current detector means operatively associated with said central needle and outer sleeve of the probe for sensing when low current electrical contact is made between the central needle of the probe and the patient'"'"'s skin and producing an electrical signal in response thereto;
means response to said electrical signal from said detector means for coupling said shortwave electrical energy to the probe central needle for cauterization of the skin pore;
and means for controlling the duration of application of said electrical shortwave energy to said central needle.

Abstract
An electrolysis system having a shortwave power source automatically energized in response to insertion of a cauterizing probe needle into the patient'"'"'s skin pore or follicle. The system includes a conductive probe and detector circuit which senses a current path being closed by contact of the needle with the patient and a power gating system which applies the cauterizing energy to the needle in controlled amounts and at a preselected time subsequent to the insertion of the needle into the pore.

7. A method for controlling the application of shortwave electrical energy to a patient'"'"'s skin pore through a probe having a conductive central needle adapted to be inserted into the pore and an outer conductive sleeve portion adapted to be held by the operator, said method consisting essentially of:
-
applying a first electrical signal of low current to said needle prior to insertion of the needle into the skin; detecting the initiation of electrical contact between said needle and the skin by sensing the portion of said first electrical signal passing from the needle through the patient'"'"'s skin, the operator and the conductive outer sleeve being held by said operator; generating a gate control signal beginning after a predetermined time interval subsequent to said detection of contact between the needle and the skin; and controlling the application of a second electrical signal of shortwave electrical energy to said needle in accordance with the magnitude and duration of said gate control signal, said first electrical signal being relatively small so as to prevent discomfort to the patient and said second electrical signal being of substantially greater magnitude than said first electrical signal so as to create cauterization of the skin pore as it passes from the needle.
