Copper Palmitoyl Heptapeptide-14 is a copper-bound, lipidized peptide used in anti-aging formulations to support collagen and extracellular matrix synthesis and improve skin firmness. It combines copper's role in tissue repair with a peptide carrier intended to enhance signaling and skin penetration.
