Plain-English identity
What is GHK-Cu?
Research explores skin appearance, wound models, collagen synthesis, extracellular-matrix organisation, inflammation and hair-follicle biology.
There is substantial laboratory and cosmetic interest, but clinical evidence varies by formulation and use. Evidence for topical formulations cannot automatically be transferred to injectable or uncharacterised research material.
