Cosmetic skin rejuvination

Abstract

A device for cosmetic treatment of human skin, including: a needle for inserting into the skin; a DC power source electrically connected to the needle for providing negative current to the needle; an anode that is electrically connected to the DC power source to receive positive current, and that is adapted to be placed in contact with the skin of the person into which the needle is inserted to form a closed electrical circuit; at least one RF transmitter coupled to the needle for radiating the area around where the needle is inserted to provide heat while the needle is deployed.

We claim: 
     
         1 . A cosmetic method for treating skin, comprising:
 deploying an array of needles to a specific depth into a person's skin;   providing a DC power source and one or more radio frequency (RF) transmitters electrically uncoupled from the array of needles;   applying a negative DC voltage to said needles from the DC power source, while the person is in contact with a positive electrode to form a closed circuit of DC current through the person's body;   providing the DC current for a pre-selected amount of time to induce a chemical reaction that forms Sodium Hydroxide at the points of contact of the needles; and   transmitting RF radiation from the one or more RF transmitters toward the deployed needles to heat up the deployed needles.   
     
     
         2 . The method according to  claim 1 , wherein said providing and said transmitting are performed simultaneously. 
     
     
         3 . The method according to  claim 1 , wherein said providing and said transmitting are performed intermittently. 
     
     
         4 . The method according to  claim 1 , further comprising supplying liquids into the skin through hollow conduits formed in said needles. 
     
     
         5 . The method according to  claim 1 , further comprising measuring electrical resistance of the circuit to determine the depth of the needles in the person's skin. 
     
     
         6 . The method according to  claim 5 , further comprising providing an indication of said depth to the user. 
     
     
         7 . The method according to  claim 1 , wherein said needles are deployed so that their tips are located in the vicinity of the muscles below the subcutaneous layer. 
     
     
         8 . The method according to  claim 1 , wherein said needles are deployed so that their tips are located in the vicinity of the collagen fibers in the dermis. 
     
     
         9 . The method according to  claim 1 , wherein said needles are deployed so that their tips are located in the vicinity of fat cells in the subcutaneous layer. 
     
     
         10 . The method according to  claim 5 , wherein the electrical resistance is measured before and after treatment to determine the level of success of the treatment. 
     
     
         11 . The method of  claim 4 , further comprising a syringe for supplying the liquids. 
     
     
         12 . The method of  claim 11 , further comprising a motor to control the supply of the liquids from the syringe into the skin. 
     
     
         13 . The method of  claim 1 , wherein said needles are partially insulated and the tips of the needles are not insulated. 
     
     
         14 . The method of  claim 1 , further comprising the step of providing one of the same or different current to each needle of the array of needles. 
     
     
         15 . The method of  claim 1 , wherein the array of needles each serve as a cathode and wherein the positive electrode serves as an anode.
