How it works
Signal
GHK-Cu is given as a subcutaneous injection on a provider-determined schedule — the SubQ route delivers a full therapeutic dose systemically, reaching skin, connective tissue, and hair follicles, not just the surface a topical serum touches.
Cellular response
GHK-Cu activates genes involved in tissue remodeling and repair. It stimulates collagen and elastin production, promotes angiogenesis (new blood-vessel formation), and has anti-inflammatory properties. The copper component is essential for enzyme function in skin repair.
Outcome
Over the following weeks most people notice better hydration and texture first, plus faster healing of blemishes or post-procedure spots (weeks 1–2), then visibly firmer skin and softer fine lines (weeks 2–4), then deeper renewal — elasticity, thicker hair, faded scarring — through weeks 4–12.
