Abstract
In electrical epilation equipment useful to permanently remove unwanted body hair it is known to have a needle electrode to affect the immediate surroundings of the papilla. In this invention the needle electrode has been adapted to fit into the first arm of a pair of tweezers where its position can be adjusted so that the needle protrudes more or less from the tip of the tweezers first arm. This feature facilitates a consistent insertion depth of the needle into the follicles. Switches adapted to fit into the tweezers control electricity flow to the needle electrode when the tweezers is being closed to grip a hair. An indicator light adapted to fit into the tweezers monitors the presence of electrical energy at the needle electrode.
