What is Copper Peptide GHK-Cu?
Copper peptide GHK-Cu is a naturally occurring tripeptide composed of three amino acids: glycine, histidine, and lysine. It binds with copper ions, creating a powerful complex that promotes healing, repair, and regeneration. First identified in the 1970s by Dr. Loren Pickart, it was found to be abundant in human plasma, saliva, and urine, though its levels decrease as we age.
The History of GHK-Cu
Dr. Pickart’s discovery of GHK-Cu was pivotal in understanding how our bodies naturally heal and repair. Initially identified for its role in wound healing, subsequent studies revealed its broader applications in anti-aging, inflammation reduction, and even hair follicle stimulation. Over the years, the peptide has transitioned from a niche scientific compound to a staple ingredient in modern skincare and health products.

Scientific Mechanisms of GHK-Cu
The efficacy of GHK-Cu lies in its ability to influence cellular and genetic functions. It modulates the activity of over 4,000 genes, promoting those responsible for repair and regeneration while suppressing inflammatory pathways. Key mechanisms include:
- Collagen and Elastin Stimulation:
GHK-Cu activates fibroblasts to produce collagen and elastin, essential for maintaining skin’s structure and firmness. - Anti-Inflammatory Action:
By suppressing pro-inflammatory cytokines, GHK-Cu helps reduce redness, irritation, and swelling. - Antioxidant Properties:
The peptide neutralizes free radicals, protecting skin and hair from oxidative damage caused by pollution and UV exposure. - Tissue Regeneration:
GHK-Cu encourages cellular turnover and repair, making it ideal for healing wounds and improving skin texture. - Hair Follicle Stimulation:
It extends the growth (anagen) phase of hair follicles, promoting thicker and healthier hair.
