Copper peptides' benefits for skin are: 1

Identification of PAD2 as a gamma-glutamylcysteine synthetase highlights the importance of glutathione in disease resistance of Arabidopsis.

The peptide reduces production of pro-inflammatory cytokines including IL-1, TNF-, and IL-6 while enhancing expression of anti-inflammatory mediators such as IL-10 and TGF-, creating a cytokine milieu that supports tissue repair rather than ongoing damage

The honest reading of the data What the study demonstrates is that copper peptide combined with microneedling produces faster initial improvement than microneedling alone
