Research has demonstrated that GHK-Cu treatment increases production of collagen (particularly type I and type III collagen, the predominant structural collagens in skin and connective tissues), glycosaminoglycans (including hyaluronic acid, which provides hydration, volume, and biochemical signaling in skin), decorin (a small proteoglycan involved in collagen fibril organization and growth factor regulation), and other matrix molecules critical for tissue structure and function

Antioxidant Gene Expression GHK-Cu upregulates superoxide dismutase (SOD) and other antioxidant enzymes, helping cells combat reactive oxygen species (ROS) that cause cellular aging and DNA damage
