Abstract

The apparatus includes at least two skin-contacting elements, the elements having narrow end faces and a mounting assembly for holding the elements closely adjacent to each other. A driving assembly reciprocally moves one element relative to the adjacent element(s) at a frequency that produces an action on the pores of the skin to loosen sebaceous plugs present in the pores, by permitting their ready removal from the skin.
