GHK-Cu Skin Serum

Description

Description

GHK-Cu serum — a concentrated 1% copper peptide topical formulation for skin research applications. This ready-to-use product delivers glycyl-L-histidyl-L-lysine copper complex in a 3mL format requiring no reconstitution. Backed by over 50 years of published research, GHK-Cu is the most scientifically studied copper peptide in dermatological literature, with documented effects on collagen synthesis, extracellular matrix remodeling, and wound repair pathways.

What Is GHK-Cu Serum?

GHK-Cu (glycyl-L-histidyl-L-lysine-copper) is a naturally occurring tripeptide-copper complex first identified in human blood plasma in 1973 by Dr. Loren Pickart. The 1% concentration in this GHK-Cu serum matches the doses used in published human clinical trials, providing researchers with a well-characterized reference concentration. The characteristic light blue appearance of the formulation confirms active copper chelation and proper peptide-copper binding — an important quality indicator for research reproducibility.

As a biological signaling molecule, GHK-Cu activates genes associated with tissue repair, collagen production, and regeneration. Broad Institute Connectivity Map analysis shows it influences approximately 6% of the human genome — making this one of the most broadly active signaling peptides in published research. For researchers studying skin biology, collagen networks, wound repair, or photoaging pathways, this topical GHK-Cu serum provides a research-ready delivery format with verified purity and batch documentation.

Key Research Applications

• Collagen synthesis: This GHK-Cu serum stimulates collagen I, III, and IV production. Published trials show up to 70% increases in collagen output in vitro and significant improvements in skin density in 12-week human clinical studies.
• Skin thickness and firmness: Clinical studies using topical copper peptide formulations documented measurable improvements in skin density, elasticity, and laxity reduction in human volunteers.
• Wound healing acceleration: The peptide promotes angiogenesis through VEGF upregulation, enhancing nutrient delivery and accelerating dermal wound closure in multiple animal and human tissue models.
• Anti-inflammatory research: GHK-Cu suppresses pro-inflammatory cytokines including TNF-α, IL-6, and TGF-β, making it directly relevant to inflammation and skin barrier dysfunction studies.
• Antioxidant pathway studies: Copper cofactor activity supports superoxide dismutase (SOD), a key enzyme protecting keratinocytes from free radical damage and oxidative stress.
• Hair follicle biology: Published data demonstrates GHK-Cu influences follicular stem cell pathways, with topical application associated with increased follicle size and reduced telogen phase in human studies.
