What Is GHK-Cu (Copper Tripeptide-1)?

GHK-Cu is a naturally occurring copper peptide found in human tissue, plasma, and saliva. It plays a role in cellular signaling and skin biology. Over time, natural levels of GHK-Cu decline.

What Does GHK-Cu Stand For?

GHK-Cu stands for Glycyl-L-Histidyl-L-Lysine Copper. It is a tripeptide that binds copper ions, forming a bioavailable complex used in cosmetic formulations.

Why GHK-Cu Declines With Age

As the body ages, natural peptide signaling decreases. This includes copper peptides involved in skin and scalp health, which is why topical cosmetic formulations are used.

What Does GHK-Cu Do for Skin?

In cosmetic formulations, GHK-Cu is commonly used to support the appearance of healthy skin and improve overall skin quality.

What Does GHK-Cu Do for the Scalp and Hair?

GHK-Cu is used in scalp formulations designed to support the scalp environment and overall hair appearance.

Why Concentration Matters in Copper Peptides

Copper peptide concentration affects how a product is formulated and used. Higher concentrations are not always better and must be carefully balanced.
