Topical GHK-Cu The topical route is the most studied and has the strongest human evidence base

Researchers investigate GHK-Cu for its involvement in copper-associated signaling pathways, gene-expression regulation, extracellular matrix biology, and cellular communication processes

Vitamin C is essential for collagen cross-linking

Next, molecular docking analysis was conducted to investigate whether GHK-Cu directly interacts with SIRT1
