A shaving unit that comprises at least one blade and a skin engaging member that has a surface for engaging the user's skin adjacent the blade edge is described herein. The shaving unit may be of a disposable cartridge type adapted for coupling to and uncoupling from a razor handle or may be integral with a handle so that the complete razor is discarded as a unit when the blade or blades become dulled. The blade edge (or edges) cooperate with skin engaging surfaces to define a shaving geometry. The skin engaging member is comprised of an elongated sheath (or skin engaging layer) made of a mixture of water insoluble matrix and an effective amount of shaving aid and a rigid core (or non-skin engaging layer) extending axially through out said sheath. The axial position of the core need not be through the central axis.
