Ad GHKCU copper peptides are fantastic for helping with skin repair signalling, antioxidant protection and Barrier care to keep your skin looking smoother and more support @cosrx The Blue Peptide Bakuchiol Plump Glow Serum and COSRX The Blue Peptide Plump Bounce Cream are fantastic starting points for a good copper tripeptide-1 formulation with additional barrier benefits, and one which I have definitely enjoyed using. GHKCU is something I’ve had in my skincare routine for a few years and definitely wouldn’t be without it. #cosrx #bluepeptideserum #bluepeptidecream #copperpeptide #peptideserum
