Short Answer
Yes — some products from The Ordinary contain:
GHK-Cu
but usually under the ingredient name:
- Copper Tripeptide-1
plutôt que : - “GHK-Cu.”

What Is GHK-Cu?
GHK-Cu stands for:
GHK−Cu=Glycyl−L−Histidyl−Lysine+Cu2+GHK{-}Cu = Glycyl{-}L{-}Histidyl{-}Lysine + Cu^{2+}
It is:
- a copper-binding tripeptide complex.
Le peptide portion contains:
- glycine
- histidine
- lysine
combined with:
- copper ions.
Why Cosmetic Companies Often Rename It
Most skincare brands use:
Copper Tripeptide-1
because:
- it follows cosmetic ingredient naming conventions (INCI naming).
Scientifically,
Copper Tripeptide-1 and GHK-Cu are closely related designations.
Which “The Ordinary” Product Contains It?
One of the best-known examples is:
Multi-Peptide + Copper Peptides 1% Serum
This formulation includes:
- copper peptide systems,
including: - Copper Tripeptide-1 (GHK-Cu–related ingredient).
Why GHK-Cu Became Popular in Cosmetic Science
Researchers study GHK-Cu because it behaves differently from:
- simple moisturizing ingredients.
Instead of acting only as:
- surface hydration support,
GHK-Cu is investigated as:
- a signaling peptide complex.
Analogie
A normal moisturizer is somewhat like:
- pouring water onto dry soil.
A peptide system like GHK-Cu behaves more like:
- sending repair instructions to maintenance workers inside the system.
What Makes GHK-Cu Different From Regular Peptides
GHK itself is:
- a tripeptide.
But when combined with:
- copper ions,
its biochemical behavior changes significantly.
Copper acts somewhat like:
- an electrical connector attached to a signaling cable.
The peptide helps:
- transport
- stabilize
- coordinate
the copper ion.
Why Copper Matters Biologically
Copper participates in:
- enzymatic systems
- oxidation-reduction reactions
- protein interactions
- extracellular matrix biology
This is why copper-peptide complexes became important in:
- biomaterials research
- peptide signaling studies
- cosmetic formulation science
Ce que la plupart des articles omettent d'expliquer
Most skincare articles simply say:
“Copper peptides help skin.”
But the deeper biochemical concept involves:
molecular signaling communication.
GHK-Cu is studied because peptide-copper complexes may influence:
- voies de signalisation
- protein interaction systems
- extracellular communication networks
rather than functioning only as:
- passive cosmetic ingredients.
Why GHK-Cu Looks Blue
Another common question.
GHK-Cu formulations often appear:
- blue
ou : - blue-green.
This color mainly comes from:
- copper ion coordination chemistry.
Analogie
The copper ion behaves somewhat like:
- a metallic core plugged into a molecular adapter.
When light interacts with that copper complex,
the solution develops:
- characteristic blue coloration.
Why Peptide Formulations Are Difficult
GHK-Cu systems are chemically sensitive.
Common instability issues include:
- oxydation
- hydrolyse
- pH imbalance
- metal ion degradation
- peptide fragmentation
That is why advanced formulations often use:
- controlled pH systems
- emballage airless
- stabilizing solvents
- low-oxygen environments
GHK-Cu vs Regular Peptides
| Fonctionnalité | Standard Peptides | GHK-Cu |
|---|---|---|
| Contains Copper | No | Yes |
| Type de molécule | amino acid chain | peptide-metal complex |
| Color | usually clear/white | often blue |
| Signaling Complexity | moderate | higher coordination behavior |
| Stability Challenges | peptide degradation | peptide + metal stability |
Why Laboratories Study GHK-Cu
Modern laboratories investigate:
- copper-peptide coordination
- peptide signaling systems
- extracellular matrix communication
- metal-assisted molecular transport
- peptide stability engineering
Final Scientific Perspective
Yes, some products from The Ordinary contain GHK-Cu–related peptide systems, usually listed as Copper Tripeptide-1. Scientifically, GHK-Cu is a copper-binding tripeptide complex studied for its signaling behavior, coordination chemistry, and peptide-mediated communication pathways in biochemical and cosmetic research.
FAQ
Is Copper Tripeptide-1 the same as GHK-Cu?
They are closely related terms commonly referring to the same copper-peptide complex system.
Why is GHK-Cu blue?
Because copper ion coordination creates characteristic blue coloration.
Is GHK-Cu a steroid?
No. GHK-Cu is a peptide-metal complex, not a steroid molecule.
Why is GHK-Cu different from normal skincare ingredients?
Because it is studied as a signaling peptide complex rather than only a moisturizing ingredient.
Why are copper peptides difficult to formulate?
Because both peptides and copper ions can become unstable under improper pH, oxidation, or storage conditions.
