The present invention addresses the need for an improved delivery system that is able to specifically target the skin for improved bioavailability and minimization of side effects resulting from administration of the active ingredient or ingredients. One aspect of the present invention is a targeting composition comprising: (1) a skin care agent or an agent that is a cosmeceutical agent; (2) an intermediate release linker bound to the skin care agent or cosmeceutical agent; (3) a targeting moiety bound to the intermediate release linker, the targeting moiety for binding the targeting composition to native collagen fibers; and (4) optionally, a carrier component to enhance delivery to the skin. The present invention also describes methods of use of these targeting compositions.
