Abstract

A makeup brush has a generally cylindrical body having a first end adapted to be rotatably couple to a motorized makeup brush support, a second end defining a recess therein that is adapted to receive a plurality of bristles, and a central axis that extends between the first end and the second end. A plurality of bristles each have a first free end and a second bounded end, where the second bounded end is configured to be received in the recess formed in the generally cylindrical body second end. In various embodiments, the free ends of a first group of the plurality of bristles are recessed with respect to the free ends of a second group of the plurality of bristles. Furthermore, the first group of the plurality of bristles is positioned radially closer to the central axis than the second group of the plurality of bristles.
