Research suggests GHK-Cu can influence the expression of genes involved in tissue repair, inflammation regulation, antioxidant defense, and extracellular matrix remodelingthe network of proteins and structural components that helps skin remain strong, resilient, and youthful
Among the genes evaluated, expression levels of genes were not significantly different in GHK and GHK-Cu group as compared to control
A randomized, controlled, blinded human trial of GHK-Cu monotherapy, with a vehicle-only control (and a needling-plus-vehicle arm if a procedure is used), objective endpoints such as blinded global photography and target-area hair counts over at least several months, adequate statistical power, pre-registration, and independent replication
