US 5,470,332 A · System for permanent removal of multiple hairs

Abstract

Multiple hair removal system includes an adhesive layer, a structural layer disposed adjacent the adhesive layer, and a conductive material. The conductive material functions to provide power from a power source to hairs to be treated that extend up through the adhesive layer and contact the conductive material. A method of removing multiple hairs and inhibiting future hair growth includes the steps of applying a conductive solution to the skin, pressing on an adhesive layer, applying power for a period of time sufficient to destroy the matrix area of the hair, and allowing the treated hair to either be removed immediately or to stay in the skin for a period of time sufficient for the chemical reaction induced at the matrix area to continue long enough to destroy the matrix area and prevent regrowth of the hair.

Claims12

Dependent claims

A hair removal system comprising:

a) a structural layer;
b) an electrically conductive adhesive layer disposed on said structural layer, said electrically conductive adhesive layer including:
i) an adhesive material, said adhesive material being sufficiently strong for adhering to and removing a plurality of treated hairs from skin;
and
ii) a plurality of conductive particles disposed in said adhesive material;
and
c) a non-conductive adhesive layer disposed on said conductive layer, and said non-conductive adhesive layer is configured to lay against skin, and to allow hair to project therethrough, and to protect a user's skin from shock and burns when in use.
