Abstract

A cosmetic applicator with disparate material application zones and a backwipe return for permitting the achievement of multiple cosmetic material application effects with a single applicator and for permitting the return of backwiped cosmetic material to a cosmetic bottle. The applicator has a wire core formed from first and second wire segments twisted into a helical configuration to form a plurality of coils. A plurality of radially disposed bristles are retained by the wire core to form a brush head. Multiple distinct bristle zones of different bristle types exhibit distinct material application properties in a single cosmetic applicator. Backwiped cosmetic material can be returned to the cosmetic bottle by a sloped shoulder at a proximal end of an applicator rod in combination with a cosmetic material passageway in a sloped facing surface of a flexible inner ring of a wiper.
