Palmitoyl Tetrapeptide-7 (GQPR Peptide)
Número CAS: 221227-05-0
Palmitoyl Tetrapeptide-7 is a lipopeptide consisting of a palmitoyl fatty acid chain conjugated to the tetrapeptide Gly-Gln-Pro-Arg (GQPR), which is a fragment of immunoglobulin G. It acts by inhibiting interleukin-6 (IL-6) signaling to suppress chronic low-grade skin inflammation (inflammaging), reduce glycation-induced cross-linking, and improve skin density. As the partner peptide to Palmitoyl Tripeptide-1 in the commercially recognized Matrixyl 3000 complex, it delivers synergistic anti-wrinkle efficacy at just 2–4 ppm use level.
