1. A cosmetic method for treating a skin of a person, comprising:
inserting one or more needles to one or more depths into the skin of the person such that at least a tip of at least one needle of the one or more needles is deployed within a muscle layer of the person's skin;
providing a DC power source electrically coupled to the one or more needles;
applying a negative DC voltage to the one or more needles from said DC power source, and a positive DC voltage to an electrode in contact with a surface of the skin of the person to form one or more closed circuits of constant DC current through the person's body; and
providing the negative and positive DC current voltages having a pre-selected value for a pre-selected amount of time, the preselected value and amount of time being configured to induce a cold chemical process in the cells surrounding the one or more needles that causes selective destruction of cells including damaging and/or ablating muscles and/or muscle nerve cells in the muscle layer;
thereby providing a skin treatment comprising causing the muscles in the muscle layer to lapse and reducing and/or smoothing wrinkles from the person's skin.
