| Mechanism | GHK-Cu chelates copper(II) ions via its histidine residue and delivers bioavailable copper directly to cells, preventing free copper oxidative damage. It stimulates collagen, elastin, and glycosaminoglycan synthesis, modulates metalloproteinases (MMPs) and their tissue inhibitors (TIMPs), attracts i... | Copper-dependent enzyme activation enhances dermal papilla cell stimulation. The copper complex promotes angiogenesis and ECM remodeling, with enhanced bioactivity compared to the non-copper form. |
