Abstract
A cosmetic applicator is provided having a brush with radially adjustable length bristles. The applicator includes a brush head, a shaft and a sleeve. The brush head has an elongated brush stem with a plurality of bristle tufts circumferentially attached radiating outwardly therefrom. A plurality of slots are provided in an end of the sleeve through which the bristle tufts are forced to protrude. The brush head and shaft to which the latter is attached are held within the sleeve. Upon rotation, the bristle tufts can wind or unwind, depending upon direction of rotation, around the brush stem. In this manner, the effective outward radial length of each bristle tuft can be rendered adjustable.
