GHK‑Cu as the active center

GHK‑Cu is the reason this line exists. Each serum is composed around Copper Tripeptide‑1, then reinforced with the specific support system needed to translate that copper signal into a distinct visible outcome.

Actives with a defined role

Every supporting active is selected to refine a visible parameter: tone, texture, contour, barrier feel, puffiness appearance, body smoothness, or surface optics. Formulas are designed to work both compositionally and visually.

A system, not a lineup

Each copper peptide serum occupies a distinct place in the line, with its own target, finish, cadence, and role within a routine. This makes selection more precise—and the results of each protocol even more apparent.

The Copper Peptide Effect

GHK‑Cu (Copper Tripeptide‑1) is the active center of the CopperPeptides line. In cosmetic formulation, it is used as a copper-binding peptide that supports the appearance of smoother, more resilient-looking, renewed skin with consistent use.

Our approach is evidence-informed and formulation-led: define the visible target, pair GHK‑Cu with the right supporting actives, and build protocols that remain realistic, stable, and repeatable.
