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.

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.
