1. A drum assembly for use with a cosmetic device, comprising:
- a generally cylindrical drum extending about and configured to rotate about a longitudinal axis, the drum including;
a cylindrical abrasive outer surface configured to abrade the skin of a user during rotation of the drum,a first end having a recess therein, the recess extending coextensively with and along the longitudinal axis and configured to receive at least a portion of a drive shaft of the cosmetic device in a rotationally fixed manner; and
a second end opposite the first end, wherein the cylindrical abrasive outer surface is positioned between the first end and the second end; and
an annular hub extending about the longitudinal axis and coupled to the second end of the drum, the hub including an annular groove extending circumferentially about the longitudinal axis, the annular groove configured to receive a support bracket of the cosmetic device.
