Abstract
A cosmetic composition including a non naturally-occurring extracellular matrix protein in combination with a cosmetic carrier is described. The protein is preferably of human origin and has not been previously cross-linked. The protein is most preferably selected from the group consisting of soluble human procollagen and soluble human tropoelastin. Preferably, the composition contains at least two allelic variants of the protein, most preferably in substantially the same ratio at which they are found in epidermis of a selected individual. The individual may be selected, for example, on the basis of having youthful-appearing skin, of being the future wearer of the composition, or of other reasons.
