GHK-Cu

Repair & Skin · Hair Injectable / Topical / Microneedling

GHK-Cu is a copper-binding tripeptide that signals tissue remodeling, wound healing, and collagen synthesis throughout the body. Its concentration declines markedly with age — which is partly why so many things stop healing as easily past 50. Delivered topically, by microneedling, or systemically for whole-body skin and tissue effects.

Best for: Wound healing, skin rejuvenation, hair density, overall tissue repair.

Frequently Asked
What clients want to know about GHK-Cu

The questions, answered.

  • Stimulates collagen and elastin synthesis in skin and connective tissue.
  • Improves skin elasticity, firmness, and tone with consistent use.
  • Supports hair follicle health and improves density in early thinning.
  • Accelerates wound healing with reduced scarring.
  • Antioxidant and DNA-protective effects.
  • Reduces fine lines, hyperpigmentation, and photo-damage over time.
  • Collagen and elastin signaling: upregulates fibroblast gene expression for matrix proteins.
  • Copper delivery: chaperones copper into cells for enzymatic processes including superoxide dismutase.
  • Anti-inflammatory and antioxidant activity at the cellular level.
  • Hair follicle stimulation via the dermal papilla cells.
  • Weeks 1–2: Skin texture and hydration begin to improve; small hairs appear in thinning areas.
  • Weeks 4–6: Visible improvement in firmness, tone, and fine-line depth.
  • Weeks 8–12: Substantial improvement in skin quality; hair density gains lock in with continued use.
  • Mild redness or sensitivity at topical or microneedling sites.
  • Transient skin tightness in first weeks of topical use.
  • Minor injection-site reaction if delivered subcutaneously.
  • Pair topical GHK-Cu with microneedling for maximum penetration and effect.
  • Apply to clean skin in the evening for overnight remodeling.
  • Use SPF daily — newly remodeled skin is more sun-sensitive.
  • Be patient: visible skin change typically takes 6–12 weeks of consistent use.
  • Wilson's disease or other copper metabolism disorders.
  • Active cancer at injection sites without provider oversight.
  • Pregnancy or breastfeeding for systemic use.
Important Note The FDA's position on peptides continues to evolve. Availability of specific compounds may change, and not all peptides discussed are currently offered at every visit. Book a consultation with our provider team to discuss your goals, current options, and what's appropriate for you.
