They function as biological signals, promoting collagen synthesis while inhibiting collagen degradation in the extracellular matrix
Users combining GHK-Cu with microneedling often report visible collagen results 3 to 4 weeks earlier than GHK-Cu alone, as microneedling creates direct channels for peptide uptake and simultaneously stimulates fibroblast activity

Two patients did not complete the treatment period due to side effects, and five more did not complete the posttreatment measurements
This does not completely negate the peptide, but it reduces efficiency
