The new formula contains actual human stem cell-derived molecules of collagen, elastin, SOD (superoxide dismutase), fibronectin and star ingredient tropocollagen, which skin produces naturally.
Postlethwaite and Kang (1976) reported that native tropocollagen, as well as peptide fragments, derived from the protein by degradation with CNBr, pepsin, or bacterial collagenase was chemotactic for monocytes.
