What was done
This narrative review synthesized published in vivo, in vitro, and gene expression profiling evidence regarding the biological activities of small copper peptides, focusing primarily on glycyl-L-histidyl-L-lysine (GHK-Cu) in skin repair and oncology.
What was found
The abstract reports no quantitative data or effect sizes. It qualitatively notes that GHK-Cu enhances wound contraction, epithelization, growth factor production, and antioxidant enzyme activity, while also presenting evidence for anti-cancer properties across small copper peptides.
Why it matters
It provides an overview of the preclinical mechanisms through which cosmetic copper peptides like GHK-Cu may promote tissue regeneration and potentially influence oncogenic pathways.
Limits
The abstract describes a narrative review without systematic search criteria or sample sizes. Reported mechanisms rely heavily on preclinical cell and animal models, lacking direct human clinical trial outcome data or quantified endpoints.
