GHK-Cu (Copper Tripeptide-1) is a naturally occurring copper-binding peptide widely utilized in cosmetic and formulation research focused on skin appearance, barrier support, and peptide-driven signaling pathways. This peptide is found endogenously in human plasma, saliva, and urine, and plays a recognized role in copper transport and cellular communication.

In cosmetic and topical research settings, GHK-Cu is commonly studied for its interaction with extracellular matrix components, copper-dependent enzymatic systems, and cell signaling mechanisms associated with skin structure and renewal. Due to its strong affinity for copper ions, it is frequently incorporated into cosmetic formulations where copper availability and peptide stability are key variables.

GHK-Cu cosmetic grade is intended for formulation development, cosmetic research, and laboratory evaluation only.
