Subsequently, 2 independent reviewers assessed the full texts of potentially eligible articles and extracted relevant data from the eligible studies
Short peptides are embedded in hydrophobic cavities in parallel through aromatic rings, enhancing - stacking, simulating the binding mode of natural substrates, and blocking the interaction between copper ion and His residues in hydrophobic cavities (Goldfeder et al., 2014)

Four molecule families have peer-reviewed clinical evidence supporting their use in microinfusion-style delivery: copper tripeptide GHK-Cu (collagen synthesis, gene-expression modulation), recombinant epidermal growth factor or sh-Oligopeptide-1 (keratinocyte proliferation, dermal restructuring), polydeoxyribonucleotide PDRN (adenosine A2A receptor activation, fibroblast stimulation, anti-melanogenesis), and a multi-molecular-weight hyaluronic acid system (50 kDa to 2000 kDa fractions, each with different penetration depth and biological role)
