Description
GHK-Cu (Copper Peptide) is one of the most researched peptides in regenerative medicine and cosmetic science.
GHK stands for glycyl-L-histidyl-L-lysine, a naturally occurring tripeptide (3 amino acids) found in human plasma, saliva, and urine. When it binds to copper, it forms GHK-Cu, the biologically active form that has been extensively studied.
What does GHK-Cu do?
Research suggests GHK-Cu may:
Skin and Anti-Aging
- Stimulate collagen production
- Improve skin elasticity
- Reduce fine lines and wrinkles
- Enhance wound healing
- Improve skin thickness and firmness
- Reduce inflammation in the skin
This is why it’s commonly found in premium anti-aging creams and serums.
Hair Growth
- May stimulate hair follicles
- Improve scalp health
- Potentially increase hair density and thickness
- Often compared to or combined with treatments like minoxidil
Wound Healing
- Accelerates tissue repair
- Promotes new blood vessel formation
- Supports remodeling of damaged tissue
- May reduce scar formation
Anti-Inflammatory Effects
- Helps regulate inflammatory processes
- May reduce oxidative stress
- Supports tissue regeneration after injury
Potential Longevity Effects
Some laboratory studies suggest GHK-Cu:
- Activates genes associated with repair and regeneration
- Suppresses genes linked to inflammation
- May improve cellular maintenance mechanisms
These findings are interesting but are mostly from laboratory and animal research.

Injectable GHK-Cu
Used in research and by some peptide users for systemic effects, though human evidence is limited.
Microneedling + GHK-Cu
Often used in cosmetic settings to support collagen production and skin rejuvenation.
Evidence Quality
Compared with many research peptides, GHK-Cu has:
- More human data for skin applications
- Decades of cosmetic and wound-healing research
- Better-established safety profile when used topically
