GHK-Cu Is the Copper Peptide Reminding Your Skin How to Heal

By Christopher Asandra, MD

In a landscape crowded with lab-made actives, copper peptides stand apart for a surprising reason: the body already knows exactly what to do with them. Few molecules earn attention not because they’re new, but because they’re native.

Copper peptides, most notably GHK-Cu, is one of those rare compounds that makes doctors stop and say, “Wait.. the body already makes this?” Naturally found in human blood and tissues, GHK-Cu acts as a repair signal, telling cells to heal, rebuild, and calm inflammation. Clinically, it’s often used after procedures or surgery because it can speed wound healing, support healthy tissue remodeling, and reduce prolonged inflammation during recovery. Research also shows it stimulates collagen and elastin, improves skin firmness, supports hair growth, and helps protect cells from oxidative stress.

Rather than forcing change, GHK-Cu reminds the body how to repair itself the way it did when we were younger, which is why it’s gaining attention not just in skincare, but also in regenerative and longevity medicine.
