A cosmetic dispenser for producing an axial movement of a cosmetic between extended and retracted dispositions. A cam member is rotatably engaged with an adapter member in a mating relationship. An elevator member with a cosmetic retaining portion and an elevator rod move axially in response to a rotation of the cam member in relation to the adapter member. A proximal end of the elevator rod can be received through an elevator aperture in the adapter member to enable a sliding of lugs on the elevator rod along a helical thread of the cam member. Frictional drag between the cam member and the adapter member can be produced by one or more drag protuberances therebetween. Where the drag protuberances project from the adapter member, a thin wall portion therein can enable a resilient deflection of the drag protuberances.
