Palmitoyl Tetrapeptide-7
Summary
Vesugen is a tripeptide bioregulator (Lys-Glu-Asp) developed by Professor Vladimir Khavinson, tissue-specific for blood vessels and the vascular endothelium. It supports endothelial cell function, promotes vascular wall integrity, and is studied for atherosclerosis prevention, vascular aging, and cardiovascular health maintenance. It is one of the more broadly applicable Khavinson bioregulators given the ubiquity of vascular tissue.
Palmitoyl Tetrapeptide-7 (Rigin) is a cosmetic peptide consisting of palmitic acid linked to the tetrapeptide sequence GQPR (Gly-Gln-Pro-Arg). It was designed to mimic the biological activity of the IgG immunoglobulin C-terminus, which downregulates the production of interleukin-6 (IL-6), a key driver of skin aging and inflammation.
