GHK-Cu (INCI: Copper Tripeptide-1) is a small peptide bound to copper. It naturally gives formulas a blue tint. Brands use it in anti-ageing and scalp serums. A label saying only "peptides" is not GHK-Cu.
Strong acids and high-strength vitamin C can be hard on copper peptides in the same step — use them at different times. Patch test.
Matched only for Copper Tripeptide-1, GHK-Cu or 'copper peptide' on the label.
Limits: No vehicle or peptide-only arm, so the effect of GHK-Cu alone is not shown.
Limits: Small, eyebrow-only; does not show scalp-hair or wrinkle results.
These studies used their own formulas and strengths. A stocked product naming the same ingredient is not proof of the same strength or result.
