The Formulations

One molecule. Three formulas.

Serum, then cream, then balm — thinnest to most occlusive, so every layer absorbs before the next one seals it in. Use one, or run all three.

Most copper-peptide formulas don’t disclose their GHK-Cu. We do — 2% / 20,000 ppm.

The Science Behind GHK-Cu

What is GHK-Cu?

A naturally occurring copper peptide involved in the skin's repair pathways, studied for over four decades. Here is what the molecule is, what we put in, and what we publish.

50+ yrs
of published research on GHK-Cu

A well-studied peptide.

Published work on GHK and GHK-Cu goes back to the early 1970s. That research is about the molecule, not about Koppā.

Common Questions

Everything you need to know about GHK-Cu.

GHK-Cu is a copper peptide your body makes naturally — part of how skin signals its own repair — and levels decline from your twenties onward. Applied at a real concentration, it supports the look of firmer, smoother skin: softened fine lines, more even tone, and a stronger-feeling barrier, building week on week. Read the science →
The 2% Serum is the core of the range and the usual first step — full-face, 2% GHK-Cu at 20,000 ppm. Prefer something you already do daily? Start with the Capsule Cream. Want one step and no routine change? The Balm Stick. The Trio is all three, in order, at 11% off.
Be patient with it. In the published literature on GHK-Cu, changes in the look of firmness, smoothness and fine lines are generally described around the 8–12 week mark — those are studies on the molecule, not on Koppā. Comfort and hydration tend to be noticed sooner. Every order carries a 30-day money-back guarantee, so you can start without committing to the timeline. Read the science →
Yes, with a little sequencing. Keep GHK-Cu and direct vitamin C (L-ascorbic acid) to different times of day — vitamin C in the morning, GHK-Cu at night — since strong acids can destabilise the copper complex. With retinol, alternate nights while your skin settles, then layer GHK-Cu first if it suits you. Nothing here is an acid, retinoid or exfoliant. Read the science →
Yes. GHK-Cu isn't an acid, retinoid or exfoliant — no purging, no peeling, no sun-sensitivity. It reinforces your barrier instead of stressing it, so it layers comfortably morning and night, even on sensitive skin. Reactive skin? Start with the Capsule Cream and build up.
