The addition of benzyl alcohol inhibits bacterial growth, allowing for multiple withdrawals from the same vial when handled properly in a sterile environment
The peptide apparently also reduced the depth of wrinkles while potentially increasing skin density and thickness after 12 weeks of experimentation in skin cell models with varying degrees of photodamage
Potential Research Domains and Implications Given the multifaceted properties of GHK-Cu, the peptide presents several promising research directions: Dermal and Mucosal Regeneration Research Research indicates GHK-Cu may support dermal repair, keratinocyte and fibroblast migration and proliferation, thickness of dermal layers, and reduction of matrix-damage markers in cellular aging models
Commercial serums offer 12-24 months unopened shelf life with professional preservative systems and 6-12 months post-opening depending on packaging (airless pump best), while DIY serums last only 1-2 weeks refrigerated without professional preservatives
