The peptide has to penetrate the outer skin barrier (stratum corneum), which limits how much active compound reaches the deeper dermal layers where collagen and elastin are produced
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)
Here is who really needs them, at what frequency, and how we approach them at CoLaz
Kids are exposed to many harmful substances daily, and they cant be kept in a bubble, either
Peer-reviewed studies demonstrate that GHK-Cu can: Stimulate fibroblast proliferation and collagen synthesis Increase glycosaminoglycan production Support wound contraction and remodeling Reduce oxidative stress and inflammation A major review published in the International Journal of Molecular Sciences describes GHK-Cu as a compound that resets gene expression to a healthier state, influencing over 4,000 human genes involved in tissue repair and anti-inflammatory processes
