Our protocol adjustments for Fitzpatrick IV-V patients using the GHK-Cu stack include more conservative SkinPen depth settings, lower needle density on the first session, an extended recovery window between sessions compared to lighter skin types, consistent mineral sunscreen guidance beginning two weeks before the first session, and careful timing to avoid treating recently tanned skin
Purity percentage, observed mass, water content, residual solvent results, and impurity profile should be reviewed together rather than treated as interchangeable quality indicators
Patients who have highly reactive or barrier-impaired skin should introduce any new GHK-Cu copper peptide product gradually and avoid combining it with strong exfoliants, retinoids, or aggressive in-office treatments
