Abstract: A rotating cosmetic applicator system features a unique rod/wiper relationship that causes the rod to rotate when it passes through the wiper. The applicator head rotates in one direction when the user inserts the applicator through the wiper, and in the opposite direction when the user removes the applicator through the wiper. The result is a more even loading of product onto the applicator head than with a conventional mascara system. A more even load of product on the brush will support a more consistent experience for the user.
