Palmitoyl Tetrapeptide-7
Also known as: Rigin, Pal-GQPR, Palmitoyl Tetrapeptide-3
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.

Key Benefits
- Reduces IL-6 inflammatory cytokine in skin
- Prevents 'inflammaging' of the skin
- Inhibits MMP collagen-degrading enzymes
- Synergistic with Matrixyl for anti-aging
- Clinically tested for wrinkle and skin texture improvement
- Well-tolerated topically
Mechanism of Action
Pal-GQPR binds to monocyte and skin cell receptors to reduce IL-6, IL-8, and GM-CSF production. By dampening chronic low-level skin inflammation ('inflammaging'), it reduces collagen degradation by MMP enzymes, maintains skin matrix integrity, and reduces the appearance of inflammation-driven aging. Often combined with Matrixyl for complementary anti-aging effects.
