GHK-Cu is a copper peptide associated with skin and collagen research. GHK is a small peptide; GHK-Cu is its copper complex. Researchers investigate that complex in cells and supporting tissue structures, as well as in specifically formulated skin products.
The studies below cover laboratory findings and a small topical-serum study.
| Main interest | Skin biology and collagen |
|---|---|
| What studies looked at | Collagen production, tissue support and wrinkle measurements |
| Study context | Cell and animal experiments; a small topical-serum study |
| Listed content | 50 mg / 100 mg per unit |
What did the collagen studies find?
- A cell-culture study found increased collagen production with GHK-Cu.
- A rat wound-chamber study found greater accumulation of collagen and other supporting tissue materials.
- The tissue study also recorded changes in collagen-related activity.

Why collagen is the main topic
Collagen is part of the structure that supports skin and other tissues. That makes collagen production and accumulation useful topics for skin-related peptide research. The GHK-Cu papers examine these processes directly, rather than simply using a broad beauty label.
The copper complex is also part of the identity. When asking about GHK-Cu, keep that full name in the enquiry.
What did the skin-serum study find?
A small study in women reported reduced wrinkle measurements after eight weeks with a specially formulated GHK-Cu skin serum compared with its control serum. The result relates to that topical serum, a different presentation from a plain research vial. Read the skin study.
GHK-Cu in the Aurelis collection
Aurelis lists GHK-Cu 50 mg and 100 mg content per unit. GLOW and KLOW use the shorter GHK abbreviation on their source sheets. Ask for the complete ingredient identity if you are considering a blend; KLOW also needs its full composition confirmed.
Our blend guide records those details alongside the standalone profiles.
