When applied topically in a properly formulated serum, GHK-Cu penetrates into the living layers of the skin where it activates a cascade of biological responses: Stimulates fibroblasts to produce collagen I, III, and VI the primary structural proteins of the dermis Activates TGF- the growth factor that signals tissue remodeling and regeneration Inhibits MMP enzymes that break down existing collagen and elastin Upregulates antioxidant enzymes including superoxide dismutase and catalase Modulates over 4,000 genes activating those associated with regeneration and suppressing those associated with inflammation and aging Stimulates proteoglycans including decorin, which regulates collagen fiber organization and gives skin its structured appearance Most skincare peptides work on a single pathway signal peptides stimulate collagen, neurotransmitter peptides relax muscles
Specifically, IL-1 is constitutively produced and retained in keratinocytes, but in response to several stimuli, IL-1 is released, which is essentially a primary event of inflammation
Studies demonstrate BPC-157 increases growth hormone receptor expression in these cells, amplifying their regenerative capacity and extending functional lifespan
