GHK-Cu (Copper Peptide)

GHK-Cu is a naturally occurring copper-binding peptide made of three amino acids (glycine-histidine-lysine) bound to a copper ion. It is widely researched for its powerful effects on skin regeneration, wound healing, and anti-aging. GHK-Cu is naturally found in human plasma but declines with age, which is why it's gaining attention in regenerative and cosmetic science.
GHK-Cu is a research peptide and cosmetic ingredient not FDA-approved for medical use. Information here is for educational purposes only.

What is GHK-Cu (Copper Peptide)?

GHK-Cu is a naturally occurring tripeptide (glycyl-L-histidyl-L-lysine) that binds to copper ions and plays a key role in tissue regeneration, wound healing, skin remodeling, and anti-aging processes. First identified in human plasma, GHK-Cu levels decline with age, but research suggests that restoring it can reverse visible signs of aging and stimulate cellular repair across multiple tissues.


Potential Benefits Shown in Studies

  • Stimulating collagen and elastin production
  • Repairing damaged skin and reducing wrinkles
  • Speeding up wound healing and reducing scar tissue
  • Supporting hair growth and scalp health
  • Reducing inflammation and oxidative stress
  • Regenerating nerves and blood vessels
  • Improving overall skin tone and firmness

Mechanisms of Action

GHK-Cu promotes healing and regeneration by:

  • Activating wound healing genes and tissue remodeling pathways
  • Stimulating collagen and elastin production in skin and joints
  • Promoting angiogenesis (new blood vessel formation)
  • Reducing inflammation and oxidative stress
  • Regulating metalloproteinases for scar-free healing and skin tightening

Because it occurs naturally in the body, GHK-Cu is well tolerated and widely studied in both dermatology and regenerative medicine.

Research Highlights

Skin Repair and Anti-Aging

Topical application of GHK-Cu has been shown to reduce wrinkles, improve skin elasticity, and enhance firmness by increasing collagen, glycosaminoglycans, and fibroblast activity.

Wound Healing and Tissue Regeneration

GHK-Cu accelerates wound closure and reduces scar formation by promoting angiogenesis, immune regulation, and tissue matrix rebuilding.

Hair Growth Stimulation

Research supports GHK-Cu's ability to stimulate hair regrowth, likely due to its effects on follicle enlargement, stem cell activation, and improved scalp circulation.
