The testis-specific phosphoglycerate kinase gene pgk-2 is a recruited retroposon
Matrixyl's mechanism is more targeted: Collagen signaling : The KTTKS sequence mimics a collagen breakdown fragment, signaling fibroblasts that collagen repair is needed Collagen types I and III : Stimulates production of the primary structural collagens in skin Fibronectin production : Enhances production of fibronectin, a key extracellular matrix glycoprotein Palmitoyl enhancement : The lipophilic palmitoyl chain improves skin penetration and receptor binding Mechanistic Comparison# Clinical Evidence Comparison# GHK-Cu Clinical Studies# GHK-Cu has multiple clinical studies supporting its anti-aging effects: Pickart facial study (67-71 women, 12 weeks) : GHK-Cu cream applied twice daily improved skin laxity, clarity, and firmness
GHK-Cu has been shown to modulate over 4,000 human genes resetting cellular behavior toward a younger, more regenerative state
In a mouse model, direct injections of human recombinant IGF-1 at two, five, and seven days after injury enhanced muscle healing in lacerated, contused, and strain-injured muscles [7]
pluvialis mono-culture at various final concentrations (0, 5, 10 and 20 ppm)
