People with Copper Metabolism Disorders: Individuals with Wilson's disease or conditions that cause copper accumulation should never use GHK-Cu, as it introduces more copper into the body
This destroys the vitamin C before it can act and may compromise the copper coordination of the peptide itself
Contraindications include Wilsons disease and hemochromatosis, both of which involve copper metabolism disorders
Therefore, copper peptides appear to refine texture and tone via barrier repair rather than direct tyrosinase inhibition
