Palmitoyl Tetrapeptide-7Anti-Aging & Longevity
Pancragen- Summary
- 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.
- Pancragen is a tripeptide bioregulator (Lys-Glu-Asp) developed by Professor Vladimir Khavinson, tissue-specific for the pancreas. It supports the function of both exocrine and endocrine pancreatic cells, promotes normalization of insulin secretion from beta cells, and may offer protective effects against pancreatic aging and diabetic progression.
