Copper Peptide Skincare

Copper peptides (GHK-Cu) are recognisable by their distinctive blue tint and are among the most talked-about peptide ingredients in skincare. This collection lists the copper peptide serums, creams and balms in the catalogue, with strengths shown on each label.

They are usually applied as a leave-on serum after cleansing. Brands often advise against layering them directly with strong acids or vitamin C in the same step.
