What it is
Plain English.
What the compound is, what it does, what it doesn't.
GHK-Cu is a copper-binding tripeptide (glycyl-L-histidyl-L-lysine + copper) first identified in human plasma in 1973. Your natural levels peak in your twenties and steadily fall — by age 60 you make roughly half of what you did at 25.
It is researched across three lanes: skin remodeling (the headline), hair-follicle support, and a wider set of tissue-repair signals. The skin results are the most-photographed. The mechanism is unusual: GHK-Cu is a signaling peptide, meaning it nudges gene expression in favor of collagen, elastin, and the matrix proteins that make skin look younger.
The substantive difference between GHK-Cu and a regular copper serum: this is the actual peptide, not just copper + amino acids mixed in. Vetted products list it as "GHK-Cu" or "Copper Tripeptide-1." Anything that omits the peptide is selling a copper complex, not the molecule.
Outcomes
What the compound delivers.
Outcome-led, not clinical jargon. The shape of the effect, in the language of the goal you're chasing.
Hair
Vetted serums and at-home microneedling protocols also report thicker, denser-looking hair at the crown and along the part. Mechanism is similar to skin — the follicle matrix responds to the same signaling.
Wound healing
First isolated from healing tissue; GHK-Cu genuinely accelerates wound repair and reduces scarring in published studies. Often the underlying reason it ends up in post-procedure skincare.
Antioxidant load
Acts as a copper carrier and indirect antioxidant — supports skin's antioxidant reserves and visibly reduces oxidative-stress markers in long-term users.
