The copper peptide GHK-Cu has a small molecular weight, making it easier for the skin to absorb. A key characteristic of GHK-Cu is its ability to form a complex with Cu ions. This is crucial because many important enzymes in the body and skin require Cu ions, playing roles in connective tissue chemical book formation, antioxidant defense, and cellular respiration. Cu ions also function as signaling molecules, influencing cellular behavior and metabolism. Sufficient Cu ion levels are a signal for stem cell proliferation and tissue repair. GHK also helps reduce the concentration of free Cu ions, preventing oxidative damage.
