What Is Copper Tripeptide-34?

Copper Tripeptide-34 is a peptide—a short chain of amino acids—bound to copper, an essential trace mineral. It functions as a skin conditioning agent in topical skincare formulations.

Copper plays a recognised role in skin physiology, including support for structural integrity and natural defence mechanisms. When formulated as a peptide complex, copper may be delivered to the skin in a stabilised form designed to support the skin barrier and overall skin health.

How It Works

Copper is a cofactor in several enzymes involved in skin health, including those that support collagen and elastin synthesis. By delivering copper in a peptide-bound form, this ingredient may allow more stable penetration and utilisation within the skin.

The peptide component helps transport the copper while the copper itself supports enzymatic processes that contribute to skin firmness and barrier function.

Clinical Evidence & References

Copper's essential role in skin physiology is well documented, particularly in supporting structural proteins and the skin's natural defences. However, clinical evidence specific to Copper Tripeptide-34 in topical skincare is limited.

Most available research examines copper's systemic or biochemical roles rather than efficacy data from cosmetic formulations. Further targeted studies would help clarify its practical benefits when applied topically at typical cosmetic concentrations.

How to Use

Copper Tripeptide-34 is typically found in serums, creams, and treatment products formulated for general skin conditioning. Apply to cleansed skin as part of your routine; it works well alongside other active ingredients. No special application technique is required.

Safety & Precautions

Copper Tripeptide-34 is generally well-tolerated in cosmetic formulations. As with any ingredient, discontinue use if irritation occurs, and perform a patch test if you have known sensitivities to copper or peptides.
