This is because of its exceptional antioxidant potency, ie, its ability to combat damage caused by oxidative stress
For research focused specifically on copper peptide mechanisms, yes GHK-Cu alone has decades of research behind it and is the gold standard for single-compound skin biology studies
What GHK-Cu adds to the formulation: Gene expression modulation across hundreds of genes including collagen genes (Type I, III), tissue inhibitors of metalloproteinases, anti-inflammatory mediators Collagen synthesis stimulation, specifically Type I and Type III collagen the structural proteins of skin, connective tissue, and many other tissues Anti-inflammatory signaling through investigated effects on TNF-, IL-6, and NF-B pathways Copper-peptide chemistry effects including cofactor activity for skin-relevant enzymes Skin-research and hair-research applications (the GHK-Cu literature in these areas is substantial) For the GHK-Cu deep-dive, see Copper Peptides Explained
