Thermodynamically stable ionic liquid microemulsions pioneer pathways for topical delivery and peptide application ScienceDirect Bounce Back Better with Peptides for Injury Recovery GHK Cu: Mechanism of Action, Collagen Stimulation, and Clinical Evidence Glow Peptide (GHK Cu) Mechanism of Action (EN) GHK Cu is a copper peptide that binds to copper ions and delivers them into cells. Copper activates repair genes responsible for collagen, elastin, How GHK Peptide Works Signaling GHK acts as a switch for skin repair: Interacts with adenosine receptors reduces inflammation Activates MAPK ERK, PI3K Akt, TGF pathways Stimulates fibroblasts & keratinocytes boosts collagen, elastin
