Skin and cosmetic peptides are a growing area of research bridging dermatology and peptide science. GHK-Cu is being studied for its potential effects on skin health, aging, and cosmetic applications.
A naturally occurring copper-binding tripeptide (Gly-His-Lys) with wound healing, anti-inflammatory, and collagen-stimulating properties. Widely studied in dermatology and tissue repair.
Also Known As
Copper Peptide GHK, Glycyl-L-Histidyl-L-Lysine:Copper(II)
What is GHK-Cu?
GHK-Cu is classified under the Skin / Cosmetic category of peptides. A naturally occurring copper-binding tripeptide (Gly-His-Lys) with wound healing, anti-inflammatory, and collagen-stimulating properties. Widely studied in dermatology and tissue repair.
Mechanism of Action: A naturally occurring copper-binding tripeptide found in human plasma that declines with age. It modulates gene expression of over 4,000 genes, promoting tissue remodeling, anti-inflammatory responses, and antioxidant enzyme production. The copper ion is essential for its biological activity.
Dermatology & Cosmetic Research
Primary Research Areas: Skin aging, wound healing, hair growth, lung tissue remodeling, anti-fibrosis, neuroregeneration.
Key Research Findings: Studies demonstrate increased collagen synthesis, glycosaminoglycan production, and decorin expression. Gene expression studies show it can reset gene patterns of diseased cells toward health. Topical application shows improvements in skin elasticity, firmness, and wrinkle reduction.
Safety Profile & Considerations
Topical applications are generally well-tolerated. Excess copper exposure is a theoretical concern with systemic use. The peptide naturally occurs in the body at declining concentrations with age.
Related Research Topics
Understanding GHK-Cu requires familiarity with these related concepts in skin / cosmetic research. Each topic represents a broader field that intersects with current peptide research.
