The review also noted that GHK-Cus copper complexation ability raises Cu2+ penetration rates across the stratum corneum, and documented the development of formulation innovations including the TriHex peptide system that combine GHK-Cu-type tripeptides with hexapeptides to produce synergistic upregulation of regenerative genes and suppression of aberrant collagen deposition
[13] Most mammalian isoenzymes have affinity for the substrate 1-chloro-2,4-dinitrobenzene, and spectrophotometric assays utilising this substrate are commonly used to report GST activity
Conclusion When used thoughtfully, copper peptides for collagen, and GHK-Cu in particular, offer a targeted way to support smoother skin, improved firmness, and healthier-looking hair
