Side-by-Side Comparison

AspectEpigenGHK-Cu (Copper Peptide)
MechanismBinds to and activates the EGF receptor (EGFR), promoting cell proliferation, migration, and differentiation. Involved in skin homeostasis and repair processes.Attracts immune cells and fibroblasts to wound sites, stimulates collagen and glycosaminoglycan synthesis, promotes angiogenesis, and has antioxidant effects. Modulates gene expression related to tissue repair.
Typical DosageTopical: Typically used at low concentrations (ppm to low %) in cosmetic formulations. Research applications vary.Topical: Applied as serum or cream 1-2 times daily. Injectable: 1-2mg daily for research purposes. Microneedling protocols often use 0.5-1%.
AdministrationPrimarily topical application for skincare. Research may use other routes for systemic effects.Most commonly used topically for skin applications. Can be injected subcutaneously for systemic effects. Often combined with microneedling for enhanced skin penetration.
Side EffectsTopical use generally well-tolerated. Theoretical concerns about promoting cell proliferation.Topical use is generally well-tolerated. May cause temporary skin irritation or redness in sensitive individuals. Injectable use may cause injection site reactions.
