The Protocol · GHK-Cu Trio — Stick · Serum · Cream
The complete GHK-Cu routine — firmer, smoother skin in three minutes a day.
Your skin is aging on multiple fronts at once — fine lines, firmness loss, uneven texture. One product won't fix all of it. The GHK-Cu Trio targets the worst lines, covers the full face with 2% GHK-Cu, and renews texture every night. Three products, three minutes.

Overview
Visible aging shows up in several ways at once. The Trio addresses them: the GHK-Cu Balm Stick concentrates nine peptides on your deepest lines, the GHK-Cu 2% Serum broadcasts 2% GHK-Cu across the full face for firmer-looking skin, and the GHK-Cu Capsule Cream renews the look of texture and seals everything in. Morning and night. Results compound week by week.

Key Benefits
-
Step 1
The GHK-Cu Balm Stick (Target) — Nine peptides directly on your concern zones. Crow's feet, lip lines, forehead. The highest local dose, exactly where it's needed.
-
Step 2
The GHK-Cu 2% Serum (Cover) — 2% GHK-Cu broadcast across your full face. The blue color means the dose is real.
-
Step 3
The GHK-Cu Capsule Cream (Renew + Seal) — Microbeads spread GHK-Cu evenly across every contour and renew the look of skin overnight. The step that makes the first two stick.

How to Use
Always start on freshly cleansed skin — a gentle cleanser is all you need first.
Three steps. Three minutes.
- 3–4 drops of the GHK-Cu 2% Serum on clean skin — press in gently, don't rub.
- Capsule Cream over the serum — massage 30 seconds to spread evenly.
- Balm Stick last, on targeted zones (lips, eyes, deep lines) — press and hold to lock everything in.
- AM: finish with SPF. PM: the Balm Stick is your final step.

Pairing & SPF
Go easy on other actives. Avoid layering GHK-Cu in the same routine as retinol, retinaldehyde, vitamin C, or strong exfoliating acids — they can irritate skin, and vitamin C can deactivate the copper peptide. Use those on alternate nights so each active can do its job.
Always wear SPF. Daily sun protection is what lets a smoother, firmer look actually show. Finish every morning with a broad-spectrum SPF 30+ to protect your results.
How It Works
Most routines layer products at random. This one has a logic: concentrate where you need it most, broadcast across the rest, then drive renewal across the whole surface.
The GHK-Cu Balm Stick targets your deepest lines first. The GHK-Cu 2% Serum covers everything else with 2% GHK-Cu that actually arrives intact. The GHK-Cu Capsule Cream uses microbeads to spread peptide evenly across every contour — and renews the look of skin in a way that compounds week on week.
Three minutes. Twice a day. Most people notice something in two weeks. The visible change builds from there.
🔬 GHK-Cu is a well-studied cosmetic ingredient, with 50+ years of independent, peer-reviewed research behind it.

What's in the Trio
Three full-size products. One protocol.
Each step has one job — treat, nourish, seal. Layered thinnest to most occlusive, morning and night, so every layer absorbs before the next locks it in.
Step 01
Treat · AM & PM
GHK-Cu 2% Serum
2% GHK-Cu on clean skin — 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
GHK-Cu 2% (Copper Tripeptide-1), Niacinamide, Hyaluronic Acid, Pentapeptide-18, Palmitoyl Tripeptide-1

Step 02
Nourish · AM & PM
GHK-Cu Capsule Cream
A ceramide-rich microbead cream that layers over the serum — its peptides and lipids absorb across every contour, conditioning and reinforcing the barrier as a light moisture layer before the final seal.
Key benefits- Ceramide-rich layer that conditions over your serum
- Restores and reinforces the lipid barrier
- Helps skin look rested and refreshed by morning
- Calms reactive and sensitive skin
Copper Tripeptide-1 (GHK-Cu), Ceramide NP, Squalane, Niacinamide, Allantoin, Panthenol

Step 03
Seal · Targeted
GHK-Cu Balm Stick
High-concentration copper peptide balm — the most occlusive step, pressed onto targeted zones (forehead, eye area, lip lines, neck, chest) as the final lock-in. Seals everything underneath into the skin and slow-releases GHK-Cu over the sealed layers.
Key benefits- Locks the layers underneath in for extended delivery
- Targets the look of fine lines at forehead, eyes, lips, neck & chest
- Supports firmer, smoother-looking skin at the point of application
- Suitable for eye area, neck, chest, and body
Copper Tripeptide-1 (GHK-Cu), Shea Butter, Beeswax, Jojoba Oil, Vitamin E, Allantoin
View full product details →Serum first, on clean skin — 2% GHK-Cu is the thinnest, highest-concentration layer, so it needs direct contact to absorb with no barrier in the way. Cream next — its ceramides and peptides layer over the serum and act as a light moisture seal. Stick last — the wax-and-oil base is the most occlusive of the three, so it works best as the final lock-in, sealing everything underneath and slow-releasing GHK-Cu over your targeted zones. In the morning, finish with SPF. The order runs thinnest to most occlusive: each layer absorbs before the next seals it in.
The Missing Peptide
Losing firmness? Your skin stopped
making the peptide behind it.
GHK-Cu is the copper peptide your skin relies on to look firm and smooth. It peaks in your twenties, then drops year after year — and as it fades, skin loses firmness, fine lines settle in, and texture turns rough. Most creams just sit on top and mask it. Koppā puts GHK-Cu back where your skin lost it.
Don't cover the signs of aging — replace what's driving them. That's the copper peptide your skin loves.
GHK-Cu is a well-studied cosmetic ingredient — with 50+ years of independent research behind it, spanning the look of firmness, texture, and barrier support.
How it works
Liposomal GHK-Cu, built to absorb smoothly.
A high concentration only matters if the peptide stays stable and absorbs well. Here's the three-step journey ours takes.
Step 1
Sealed to survive
Each GHK-Cu molecule is wrapped in a lipid shell — so it stays stable instead of evaporating on the surface like most peptide serums.
Step 2
Absorbs smoothly
That shell helps it absorb evenly instead of sitting and drying on the surface like many peptide serums.
Step 3
Improves the look over time
GHK-Cu is a well-studied cosmetic peptide that helps improve the look of firmness, texture, and tone with continued use.
Why GHK-Cu?
New to copper peptides? Start here.
As skin ages, it makes fewer of the signals that keep it firm and smooth — so it repairs more slowly and lines settle in. GHK-Cu is a copper peptide your body already makes on its own. Applied to the skin at a real concentration, it helps prompt the look of firmer, healthier skin over time.
Where most peptide serums stop, ours starts.
A typical "peptide serum" leans on botanical filler and a low dose of copper peptide. Here are the same formula decisions, side by side.
Comparison reflects typical formulations in the prestige peptide-serum category. Ingredient positions are based on published INCI lists.
How it compares
Retinol, vitamin C, or copper peptide?
General guidance — actual results depend on formulation and concentration. GHK-Cu is gentle enough to pair with the others on alternate days; keep pure vitamin C in the morning and copper peptide at night.
Is it right for you?
Who it's for — and who it isn't.
Best for
- Fine lines and early wrinkles
- Loss of firmness
- Crepey, uneven texture
- Dull, tired-looking skin
- Sensitive skin that reacts to actives
- Preventative, everyday care
Not ideal if
- You want an exfoliant or a peel
- You want instant, temporary tightening
- You're specifically treating active acne
- You expect overnight results — this builds over weeks
The results
What changes — and when.
With consistent daily use, here's an illustrative timeline of what many people notice over time. Individual results vary.
Smoother & calmer
Skin feels softer and more hydrated; texture starts to even out.
Visibly refined
Tone looks more even, pores look smaller, skin looks fresher.
Firmer & bouncier
Fine lines look softened and skin feels firmer and more resilient.
Lasting change
Firmness and glow that build and hold with continued use.
Based on the typical GHK-Cu response window. Individual results vary with consistency and skin type.

Day 28, and my before photo versus today made me emotional. Jaw-line is back. Fine lines around my eyes are visibly softer.
Three minutes is not a marketing claim. I timed it. Three minutes and I am done. Skin has not looked this good since my mid-20s.
I sent my dermatologist the ingredient list expecting pushback. She said the GHK-Cu research is solid and told me to keep going. That was the validation I needed.
I put my 62-year-old mother on this in January. It is now week 14. She called me crying. The before and after is something I would not have believed if I had not seen it myself.
Three minutes. I timed it. Stick, Serum, Cream. That is the whole thing. I have not had a better return on three minutes in my life.

How to Use
Three steps. Three minutes.
- 3–4 drops of the GHK-Cu 2% Serum on clean skin — press in gently, don't rub.

- Balm Stick last, on targeted zones (lips, eyes, deep lines) — press and hold to lock everything in.
- AM: finish with SPF. PM: the Balm Stick is your final step.
Before you ask
Frequently asked results.
When will I see results?
Hydration and surface texture often improve in 2–4 weeks; the look of firmness and softer lines builds over the following weeks with daily use.
Can I use it with retinol?
Yes — just alternate nights rather than layering both in the same session, so neither adds unnecessary irritation.
Can I use it with vitamin C?
Yes, with timing: keep pure vitamin C in the morning and GHK-Cu at night — vitamin C can deactivate copper peptides if layered together.
Can I use it twice daily?
Yes. GHK-Cu is gentle and designed for morning and night. In the morning, finish with SPF.
Is it safe for sensitive skin?
Generally yes — it's not an acid, retinoid, or exfoliant, and it supports the barrier rather than disrupting it. Patch test first if you're highly reactive.
Can I use it around the eyes?
Yes — apply gently to the orbital bone area, avoiding direct contact with the eyes themselves.
