2% GHK-Cu full-face serum — the high-strength active. Applied to clean skin first, it's the thinnest, highest-concentration layer, so it absorbs directly with nothing in its way and carries copper peptide across the full face and neck.

Key benefits
  • 2% GHK-Cu (a high concentration)
  • Supports firmer, smoother-looking skin across the full face
  • Visible improvement in the look of firmness and skin texture
  • Helps soften the look of lines over time

Deliver the actives. Nourish the barrier. Seal it all in.

Each product runs one step of the copper-peptide repair cycle — used together they complete a loop a single product can't. That's why it's a protocol, not three separate buys.

Why the protocol works

Three different steps, one repair loop.

Treat, nourish, seal — each step builds on the last. Here's how that differs from a typical routine.

A typical routine
The Koppā protocol
Copper peptide dose
Lower peptide concentrationsOften too little to see change.
Clinical 2% GHK-Cu serum at the core of the routineEnough to visibly firm and smooth.
How the steps fit together
Three products doing similar jobsOverlap instead of progression.
Treat, nourish and seal — one repair loopEach step sets up the next.
What's doing the work
Fragrance- and texture-led formulasPleasant — but not doing the repair work.
Targeted peptides plus barrier lipids — no fillerEvery ingredient earns its place.
How it feels on skin
Can feel stripping or drying over timeHard to stick with daily.
Niacinamide, squalane and jojoba oil add a moisturising layerComfortable enough to use daily.
The result
Slow, hard to tell if it's workingEasy to give up before you see change.
Firmer, smoother, more even skinVisible change you can point to.
2–3 weeks Smoother, softer texture
Week 6 Visibly firmer, lines softened
Ongoing Full result with continued use

Comparison reflects typical three-step peptide routines in the prestige category. Timelines are based on customer-reported results using the full protocol daily.

One product vs. all three

What changes when you use the full routine.

These aren't reviews of one product. They're from customers who upgraded to the full GHK-Cu routine — and noticed the difference.

Customer applying the Koppā GHK-Cu copper peptide cream
★★★★★

"I started with just the GHK-Cu 2% Serum. Good results — texture looked better in three weeks. Then I added the full trio. By week six I could see visible change. Firmer-looking. The lines on my forehead looked visibly smoother. The serum alone didn't do that."

"Was using the GHK-Cu Balm Stick for a month. Results were real. Added the serum and barrier balm and two weeks later I understood what 'layered repair' actually means. This is a system, not three separate products. You feel the difference."

"Three products, three minutes — I was sceptical I'd stick to all three steps. Five weeks later it's completely automatic. And my skin looks visibly different. Not just glowy. My cheekbones look more defined. Lifted."

Good to know

Your GHK-Cu routine questions, answered.

Model applying the GHK-Cu 2% Serum

Using the routine

How long until I see results?
Most customers notice smoother texture within 2–3 weeks. Firmer-looking skin and softened lines typically show from week 6, with results building the longer you stay consistent.
Add the Trio — $175.00 →
In what order do I apply the three products?
Apply the 2% GHK-Cu Serum first, then the Capsule Cream with 0.5% GHK-Cu, niacinamide and squalane. Finish with the 0.5% GHK-Cu Balm Stick on targeted dry-feeling areas. In the morning, apply SPF last. The Trio includes all three products at $15.00 off.
Get all three — Add the Trio, $175.00 →
Is the routine the same morning and night?
Yes — identical three steps, twice a day. At night, be slightly more generous with the Capsule Cream, since overnight occlusion drives the most visible change. One simple routine that fits into any morning and evening.

Ingredients & compatibility

Can I use this with retinol or other actives?
Yes. GHK-Cu is gentle and pairs well with most routines — hyaluronic acid and niacinamide are already built in. Two things to stagger: keep pure vitamin C in the morning and the Trio at night (vitamin C can deactivate copper peptides), and use strong acids or retinol on alternate evenings rather than layering them in the same session. Otherwise the Trio slots straight into what you already use.
Add the Trio to bag — $175.00 →

Skin types

Is it suitable for sensitive skin?
Yes. GHK-Cu has no known irritation profile — it's not an acid, retinoid, or exfoliant, and it reinforces the skin barrier rather than disrupting it. Still unsure? Take the two-minute routine quiz for a personalised recommendation.

How long does the Trio last?

Add the Trio — $175.00 →
Do I need all three, or can I start with one?
You can start anywhere, but the three are built to work as one system: the Balm Stick targets, the 2% Serum delivers across the full face, and the Capsule Cream seals it in overnight. Skin changes fastest on the complete protocol — and the Trio is the simplest way in, with all three steps in one box at $15.00 off buying them separately.
Start with the full protocol — $175.00 →
What if it doesn't work for my skin?
GHK-Cu suits most skin types, and results build with consistent daily use. If you have any trouble with your order or aren't sure it's the right fit, our team is on hand — just email us and we'll help you get the most from the routine.
