Modulation of epithelial permeability by extracellular macromolecules
What GHK-Cu adds to the formulation: Gene expression modulation across hundreds of genes including collagen genes (Type I, III), tissue inhibitors of metalloproteinases, anti-inflammatory mediators Collagen synthesis stimulation, specifically Type I and Type III collagen the structural proteins of skin, connective tissue, and many other tissues Anti-inflammatory signaling through investigated effects on TNF-, IL-6, and NF-B pathways Copper-peptide chemistry effects including cofactor activity for skin-relevant enzymes Skin-research and hair-research applications (the GHK-Cu literature in these areas is substantial) For the GHK-Cu deep-dive, see Copper Peptides Explained
When nitric oxide levels are low, blood flow can be limited due to constricted blood vessels, and your cells wont get enough oxygen or nutrients
This helps maintain mitochondrial homeostasis and exerts neuroprotective effects, highlighting a potential mechanism for its therapeutic action
