The peptide your skin already knows.
1% GHK-Cu copper peptide serum. Clinically studied. Naturally occurring. Now in a bottle.
GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring peptide first identified in human blood plasma in 1973. Your body already produces it. It is one of the most studied peptides in cosmetic science, long valued for its association with firmer, smoother, healthier-looking skin.
The problem: GHK-Cu levels in your body decline steadily with age. By 60, you have roughly 60% less than you did at 20. A topical copper peptide serum helps skin look replenished, firm, and resilient, the way it looked when it was younger.
GHK-Cu supports your skin's appearance in more ways than one. Not a single trick. A system.

GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring peptide found in human blood plasma, saliva, and urine. Discovered in 1973, it is one of the most extensively studied peptides in cosmetic skincare, long valued for its role in the look of firm, smooth, healthy-looking skin.
GHK-Cu is generally well-tolerated and is often chosen for sensitive skin. That said, we recommend a patch test on a small area before full application. If irritation occurs, discontinue use and consult your dermatologist.
Most users notice improved hydration and skin feel within the first 1-2 weeks. Texture and tone improvements typically appear around weeks 4-6. For visible firmness and fine line reduction, consistent use over 8-12 weeks aligns with clinical study timelines. Skincare is a long game.
Yes, but with a caveat. GHK-Cu and retinol can complement each other, but using both simultaneously may increase sensitivity. We recommend applying GHK-Cu in the morning and retinol at night, or alternating evenings. Listen to your skin.
