GHK-Cu Copper Peptide
GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is a naturally occurring human plasma tripeptide that binds copper ions with high affinity. First isolated in 1973, it has since become one of the most extensively researched peptides in dermatology, wound healing, and anti-aging science — with studies showing it can reset gene expression patterns in aging tissue.
Research Highlights
Skin Regeneration
GHK-Cu is one of the most studied peptides in dermatology research. It stimulates collagen, elastin, and glycosaminoglycan synthesis, and activates skin remodeling enzymes. Studies show it tightens loose skin and improves elasticity.
Wound Healing
Research demonstrates GHK-Cu's potent ability to accelerate wound closure. It attracts immune cells and fibroblasts to wound sites, promotes angiogenesis, and stimulates the synthesis of decorin — a proteoglycan critical for proper scar formation.
Anti-Inflammatory Activity
GHK-Cu has been shown to reduce oxidative damage and modulate inflammatory gene expression. Studies indicate it blocks the release of pro-inflammatory cytokines and free radicals, making it relevant in chronic inflammation research.
Gene Expression Regulation
One of GHK-Cu's most remarkable properties is its ability to reset gene expression patterns. Research shows it can upregulate over 30 genes associated with tissue repair and downregulate genes linked to inflammation and cancer progression.
Mechanism of Action
GHK-Cu works through multiple overlapping mechanisms. Its copper-binding capacity is central to its biological activity — the Cu²⁺ ion acts as a cofactor for enzymes involved in collagen cross-linking (lysyl oxidase) and antioxidant defense (superoxide dismutase).
At the gene expression level, GHK-Cu has been shown to modulate over 4,000 human genes — upregulating those involved in tissue repair and metabolism while downregulating genes associated with inflammation, cancer progression, and cellular senescence.
It also activates matrix metalloproteinases (MMPs) and their inhibitors in a balanced manner, enabling proper tissue remodeling without excessive degradation — a key mechanism in both wound healing and skin rejuvenation research.
