1. A skin treatment kit comprising:
- a) a skin treatment device comprising;
i) a housing with a handle end extending to a neck portion and an applicator attachment end, said housing containing a battery, a motor adapted to impart a rotary motion to an output shaft when actuated, said output shaft extending through said applicator attachment end and coupled to an applicator shaft portion, and further comprising a power switch for said motor, andii) an applicator coupled to said applicator shaft portion of said housing such that the rotary motion of said output shaft is imparted to said applicator; and
b) a personal care composition comprising;
i) from about 0.01% to about 25%, by weight of the composition, of a particulate material, said particulate material having an average primary particle size from about 90 μ
m to about 600 μ
m, andii) a dermatologically acceptable carrier.

Abstract
A personal skin polishing or microdermabrasion device having a convenient form factor with a applicator attached to a contoured housing with a handle portion. The housing contains a battery, a cordless motor and a gear box to provide an appropriate rotational velocity to the output shaft that is coupled to the applicator. The applicator may be a foam material selected to cushion the skin from excessive abrasion to the particles in a personal care composition to be used with device, and to have a porosity that will enable the foam to interact with the particles and enhance the skin polishing effect.

30. A skin treatment device comprising:
-
a housing containing a battery, a motor and a motor output shaft in axial alignment along a first axis and a gear mechanism coupled to said motor output shaft that transmits the rotary motion of said motor output shaft to a first boss and a second boss counter-rotating about a second axis, wherein said first and second axes are perpendicular with respect to one another; and a first skin treatment surface attached to said first boss such that the rotary motion of said first boss rotates said first skin treatment surface. a second skin treatment surface attached to said second boss such that the rotary motion of said second boss rotates said second skin treatment surface, wherein the first skin treatment surface and the second skin treatment surface are co-planar. - View Dependent Claims (31)
