Copper peptide GHK-Cu formulated for combined topical and subcutaneous application. Activates TGF-beta signaling and upregulates VEGF, FGF, and HGF expression in dermal fibroblasts. Stimulates type I and III collagen synthesis, increases hyaluronic acid and dermatan sulfate (GAG) production, and enhances fibroblast proliferation and migration. Restores dermal extracellular matrix architecture, increases skin hydration and elasticity, reduces fine lines and pore size. SubQ dosing provides systemic benefits; topical targets facial skin directly.
Apply topically to face/neck daily, or inject SubQ for systemic benefits. Can be added to serums or creams. Consistent daily use for 8+ weeks for visible results.
