1. An apparatus for treatment of acne, comprising:
at least two contacting elements having end faces, all of the end faces being in substantially the same plane, wherein at
least one contacting element is a moving contacting element, the end faces of the moving contacting element moving in a single
plane;
a mounting assembly for holding the contacting elements substantially adjacent to each other; and
an assembly for positively moving said at least one moving contacting element bi-directionally about a neutral position relative
to at least one adjacent contacting element, to produce alternating tension and compression of the skin, wherein when the
apparatus is positioned so that the end faces of the contacting elements contact the skin, an action on the skin in the plane
of a skin area to be treated for acne is produced to remove sebum plugs from skin pores, permitting ready removal thereof
from the skin.
