The most extensively researched cosmeceutical peptide — naturally occurring copper-chelating tripeptide with 50+ years of published research.
GHK-Cu (Gly-His-Lys : Copper) was first isolated from human plasma in 1973. Across five decades of research, it has accumulated one of the broadest research profiles of any cosmeceutical compound — spanning dermal fibroblast biology, wound healing mechanisms, antioxidant pathway activation, and hair follicle biology.
MECHANISM OF ACTION
Multi-Pathway Dermal & Systemic Biology
Collagen synthesis: Studied for upregulation of Type I and III collagen and elastin production in dermal fibroblast cell models via TGF-β pathway modulation.
Antioxidant activation: Copper-dependent superoxide dismutase and catalase enzyme activity upregulation studied across oxidative stress models.
Hair follicle biology: Keratinocyte proliferation and follicular cell signaling studied in hair growth model systems using GHK-Cu as substrate.
