Research Overview
GHK-Cu is a naturally occurring copper-binding tripeptide complex (Glycyl-L-Histidyl-L-Lysine bound to Cu²⁺). It is one of the most well-characterized peptides in dermal and matrix-remodeling research, with decades of published in-vitro literature on collagen synthesis, antioxidant gene expression, and skin barrier dynamics.
Mechanism of Action
GHK-Cu acts as a copper-delivery system to cells. Once internalized, the copper ion participates in matrix metalloproteinase regulation, collagen and glycosaminoglycan synthesis pathways, and modulation of gene clusters associated with tissue remodeling in research models.
Research Applications
- Dermal fibroblast collagen synthesis
- Antioxidant gene expression studies
- Matrix metalloproteinase modulation
- Hair follicle dermal papilla research
