Standard technique involves using 29 to 31 gauge insulin syringes with 1/2 inch needles for subcutaneous administration
According to a widely cited mechanism review by Pickart and Margolina (International Journal of Molecular Sciences, 2018), GHK-Cu has been shown in laboratory and gene-expression research to: Stimulate collagen and glycosaminoglycan synthesis, which supports the skin's structural matrix Increase antioxidant enzyme activity, including superoxide dismutase, which helps neutralize free radicals Modulate matrix metalloproteinases (MMPs) the enzymes involved in both tissue breakdown and tissue remodeling Reduce inflammatory signaling, including suppression of TNF-alpha and other pro-inflammatory pathways If you want the fuller picture of how this tripeptide behaves in skin generally, before narrowing in on flare-prone conditions, we cover it in What Is GHK-Cu
