It works by reducing melanin production, resulting in: A brighter, more even skin tone
These proteins included extracellular vesicle interleukin-2 (EV IL2) and cathelicidin antimicrobial protein (CAMP) which were elevated, while immunoglobulin lambda variable 1-47 (IGLV1-47), cartilage acidic protein 1 (CRTAC1), leucine-rich alpha-2-glycoprotein 1 (LRG1), insulin-like growth factor 1 (IGF1), and tubulin alpha-1 (TUBA1) were decreased relative to healthy controls
Key Takeaway: The GHK-Cu literature remains largely pre-clinical, with stability handling and sourcing variability as the two operational risk factors most likely to compromise research reproducibility
