- Both GHK-Cu (copper tripeptide) and collagen peptides (hydrolysed collagen, containing bioactive dipeptides such as Pro-Hyp and Hyp-Gly) are investigated for skin regeneration and extracellular matrix biology. Their mechanistic profiles are distinct — GHK-Cu acts as a cell-signalling molecule engaging specific receptors and transcription factors, while collagen peptides primarily function as substrate/precursor signals for fibroblast collagen synthesis. This comparison examines the receptor biology, downstream effectors, and research endpoint differences between these two approaches to dermal ECM research.
