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.
