Our study showed that CuCl 2 and Cu(OAc) 2 had significantly upregulated HaCaT cell expression of IL-1 and IL-8 at both the gene level and protein level
However, it is not recommended to combine it directly with high concentrations of vitamin C (L-ascorbic acid) or AHAs, as the acidic pH of these actives can destabilize the copper complex and reduce GHK-Cu efficacy
Over time, many patients choose to combine peptides with other treatments such as microneedling, skin treatments, or wellness therapies to support even better results
For patients dealing with stubborn soft-tissue injuries, post-surgical recovery, or chronic inflammation, either peptide is worth discussing with a qualified provider
