Description

GHK-Cu (Glycyl-L-Histidyl-L-Lysine copper complex) is a naturally occurring peptide found in human plasma, first identified in the 1970s by researchers at the University of California, San Francisco. Studies published in journals such as the Journal of Investigative Dermatology have shown that GHK-Cu may stimulate collagen, elastin, and glycosaminoglycan synthesis, while also exhibiting anti-inflammatory and antioxidant properties. Research further suggests it can modulate gene expression related to tissue regeneration, wound healing, and skin health. For these reasons, it is widely studied in dermatology, aesthetics, and regenerative medicine.
