GHKCU

Description

GHK-Cu (often written as GHK copper peptide) is a naturally occurring copper-binding peptide made of three amino acids:

glycine–histidine–lysine (GHK) attached to a copper ion (Cu²⁺).

It’s found in small amounts in human blood, saliva, and tissue, and levels tend to decline with age.

What it does in the body (biological role)

GHK-Cu is involved in tissue repair and regeneration signaling. Research suggests it can influence:

* Wound healing

* Collagen production (skin structure)

* Anti-inflammatory signaling

* Antioxidant protection

* Blood vessel formation (angiogenesis)

* Gene expression related to repair and regeneration

⸻

Why it’s used in skincare and cosmetics

GHK-Cu is popular in skincare because it may:

* Improve skin firmness and elasticity

* Reduce fine lines and wrinkles

* Support skin healing and regeneration

* Improve overall skin texture

You’ll often find it in serums and creams marketed for “anti-aging” or “skin repair.”

⸻

Medical / research interest

Scientists have studied it for:

* Wound healing therapies

* Hair growth support

* Possible nerve repair and anti-inflammatory effects

But most evidence is still preclinical (cell/animal studies) or early human data.

⸻

Simple summary

GHK-Cu is a copper-linked peptide your body naturally has that helps regulate healing and tissue repair. It’s widely used in skincare, but stronger medical uses are still under research.
