GHK-Cu: the copper peptide behind BonPatch GLOW
What is GHK-Cu?
GHK-Cu stands for glycyl-L-histidyl-L-lysine copper complex. It is a naturally occurring copper peptide found in the human body, and it has been a subject of research interest since it was first isolated in human plasma in the early 1970s.
Why formulators are interested in it
The molecule is made of three amino acids, glycine, histidine and lysine, bound to a copper ion. Copper is an essential trace mineral, and copper peptides have been studied for decades in the context of skin science. GHK-Cu now appears widely in serums, creams and wearable formats across the beauty category.
It is most often discussed in relation to the appearance of firmness and elasticity, and for its antioxidant properties. Research continues, and the picture is still developing rather than settled.
How to use products containing it
GHK-Cu appears in serums, creams and patches. Choose formulations suited to your skin type, patch test anything new, and speak to a skincare professional if you are unsure.
