Copper Tripeptide-1
Copper Tripeptide-1 (GHK-Cu) is a naturally occurring copper complex formed from the tripeptide GHK (glycine-histidine-lysine) bound to a copper(II) ion. It is found endogenously in human plasma, saliva, and urine, with concentrations declining significantly with age. It works by stimulating fibroblasts to produce collagen, elastin, proteoglycans, and glycosaminoglycans, while simultaneously breaking down damaged or overly cross-linked scar tissue collagen — effectively remodelling the extracellular matrix. It also activates antioxidant enzymes such as superoxide dismutase and exerts anti-inflammatory effects through gene regulation.

Adenosine is a naturally occurring purine nucleoside found in all living cells, where it plays a vital role in energy transfer (as part of ATP) and cell signalling. Applied topically, it acts as a cell-communicating ingredient that can interact with adenosine receptors in the skin to stimulate collagen production, support barrier repair, and reduce visible signs of ageing. It is well tolerated and widely used in anti-ageing serums and creams.
