Copper Tripeptide-1 · TRIPEPTIDE-1Active
Tripeptide bound to copper. Wound-healing, collagen synthesis, antioxidant — well-studied for trace amounts.
What it does
GHK-Cu was first identified for its role in tissue repair. Topical copper peptides have evidence for wound healing and collagen support. Anecdotally popular for skin recovery; the formal cosmetic evidence is moderate.

debatedCopper peptides may be oxidized by direct vitamin C if applied in the same step. Practical impact in real cosmetic products is debated, but a separate-step routine is the conservative move.Pickart 2015 · BioMed Research International ↗

Graded per the methodology: strong · moderate · emerging · expert consensus. A weak source on a strong claim gets the weaker label.
