Copper peptides, explained
What is GHK-Cu in skincare?
GHK-Cu is a copper peptide: a small chain of amino acids bound to copper. Also called Copper Tripeptide-1, it is studied for its role in the skin’s natural renewal and collagen processes. In skincare, it is used to support smoother, firmer-looking skin, alongside ingredients that keep skin hydrated and comfortable.
The GHK-Cu stick. Targeted care, wherever you go.
Twist up, glide on and go. This water-free GHK-Cu balm stick makes targeted skincare easy at home, at the gym or when travelling. One light pass delivers peptide care with jojoba oil and squalane to soften dry-feeling skin on the face, neck, hands, elbows and knees.
Eye area
Glide gently around the outer eye area to soften dry-feeling skin and the look of fine lines. Keep away from the lash line and avoid direct eye contact.
Forehead
A light pass over the forehead adds targeted moisture, helping skin feel smoother and keeping dryness-related lines less noticeable.
Jaw + neck
Glide along the jaw and down the neck for softer, more comfortable skin where shaving and daily exposure can leave it feeling dry. Use on intact, non-irritated skin.
Body
Swipe over hands, elbows and knees to soften rough, dry-feeling patches. The balm helps hold in moisture in areas that need extra care throughout the day.
Three simple steps
Treat, hydrate and target. Built to work together.
Three formulas. One routine.

How GHK-Cu supports the skin’s natural renewal processes.
GHK-Cu science
How does GHK-Cu work for your skin?
GHK-Cu is a copper peptide studied for its role in the skin’s natural renewal processes. Think of it as a signal that helps skin cells communicate. Research explores how it supports collagen and elastin, the proteins that give skin its firmness and bounce. In topical skincare, the aim is smoother, firmer-looking skin over time. How well it works depends on the complete formula and how the ingredient reaches the skin.
The skin science, made simple
- Collagen support
- GHK-Cu is studied for its role in collagen production, which helps maintain the skin’s structure and firmness.
- Skin renewal
- Research explores how this copper peptide supports the skin’s own renewal and maintenance processes.
- Daily care
- Peptide care works within a routine: hydration keeps skin comfortable, while daily sunscreen helps protect it from sun damage.
Koppā, in use
Real routines. Less effort.
Straightforward skincare, shown in daily use.
Everyday peptide care
“Products are quick, and easy to use. Cream actually has the blue capsules, which I was skeptical of. My skin just looks better overall.”
Post-shave care
“I've never been a skincare guy. But I use these daily- especially the stick after shaving.”
Easy to use
“I started with the serum because my wife uses it. I have to say, it feels good on my skin. Not greasy or shiny.”
Actually stuck with it
“Bought the whole Protocol. Didn’t expect the stick to be my favourite, but it’s the one I use the most.”

Choosing copper peptide skincare
Serum, cream or balm?

Compare the formulasGHK-Cu copper peptide questions, answered.
What is GHK-Cu?+
GHK-Cu is a copper peptide, also listed as Copper Tripeptide-1. It is studied for its role in skin renewal and collagen production. Koppā offers GHK-Cu skincare for men in a serum, cream and balm stick, so you can choose the texture and care your skin needs.
Do I need all three Koppā products?+
No. The serum adds a lightweight peptide step, Capsule Cream provides daily moisture, and the Balm Stick targets dry-feeling areas on the face and body. Choose one according to your needs. The complete Protocol includes all three, but it is optional.
Can copper peptide skincare fit into a post-shave routine?+
Choose post-shave care according to the formula’s directions and how your skin feels. Koppā’s cream provides moisture, while the balm is intended for targeted dry-area care. We do not claim that these formulas treat razor burn or heal shaving cuts. Avoid applying to broken or irritated skin.
How soon will I notice a difference?+
Our promise is a focus on skin longevity: helping your skin stay healthy-looking over time by supporting what it already knows how to do. GHK-Cu is studied for its ability to stimulate collagen production — a natural process that helps keep skin firm. Our routine pairs this peptide care with hydration, giving skin a daily boost. You may notice softer, more comfortable skin first; visible changes take consistent use and vary from person to person.
Can I use copper peptides with retinol or exfoliating acids?+
Follow the directions for each formula. Koppā’s Balm Stick guidance recommends introducing combinations with retinoids, exfoliating acids or other intensive treatments gradually, according to your skin’s tolerance. This is product-specific guidance, not a blanket rule that all copper peptide formulas are compatible with every active ingredient.
