Abstract
An injectable composition having dermal filling and tissue expanding activity comprises: (1) a quantity of elastin sufficient to bring about dermal filling and tissue expansion when injected into a subject in need of dermal filling and tissue expansion; and (2) a pharmaceutically acceptable carrier. The composition can further comprise collagen; in other alternatives, the composition can further comprise hyaluronic acid; and one or more of the elastin, the collagen, and the hyaluronic acid, if present can be cross-linked, either intramolecularly or intermolecularly. The elastin, however, is the primary filler, even if collagen or hyaluronic acid are included in the composition.
