A comprehensive review of GHK-Cu (copper peptide) skin research, covering its discovery, mechanisms of action, gene expression data, clinical trials, and wound healing properties.
History and Discovery of GHK-Cu
The journey of GHK-Cu began in 1973 when Dr. Loren Pickart first isolated the tripeptide glycyl-L-histidyl-L-lysine (GHK) from human plasma albumin, observing its ability to stimulate liver tissue regeneration.
Key Mechanisms of Action in Skin Regeneration
GHK-Cu exerts its beneficial effects on the skin through a multifaceted approach, influencing several critical biological pathways including collagen synthesis, matrix metalloproteinase regulation, and antioxidant defense.
Gene Expression Modulation and Anti-Aging Effects
A pivotal study revealed that GHK-Cu modulates 31.2% of human genes, with 59% being upregulated and 41% downregulated, impacting pathways related to aging, tissue repair, and cancer suppression.
