Description
Palmitoyl Tetrapeptide-7 Overview
Palmitoyl Tetrapeptide‑7 is a synthetic peptide derived from a four-amino-acid fragment of immunoglobulin G, enhanced with palmitic acid for improved skin absorption. It helps reduce pro‑inflammatory cytokines like IL‑6, supports collagen and elastin synthesis, and is widely used in gentle anti-aging cosmetic formulations.
It’s frequently featured in peptide blends (e.g. Palmitoyl Tripeptide‑1 + Tetrapeptide‑7), shown to boost skin resilience, reduce redness, and improve elasticity in 8–12 week studies.
For cosmetic formulation and laboratory research use only. Not for injection, ingestion, or therapeutic use.
