Palmitoyl Tetrapeptide (Rigin) Research

Palmitoyl Tetrapeptide was originally developed as a potential immunostimulatory and neurotrophic (can regrow nervous tissue) peptide. It is still under active investigation for its ability to encourage nerve healing, particularly after burns and tissue grafts [2].

Recently, interest in rigin has increased among researchers involved in trying to understand how extracellular matrix (ECM) growth is modulated. Palmitoyl Tetrapeptide is being investigated in animal models for its ability to influence collagen and elastin synthesis in the ECM and thus for its ability to improve skin elasticity and firmness [3].

Palmitoyl Pentapeptide-3 (Matrixyl) Research

Matrixyl is a lipopeptide, a fatty acid mixed with amino acids. It is also considered to be a synthetic isomer (an isomer is a molecule that has an identical structure to another molecule but different atomic components). The active element in Matrixyl is called Micro-collagen - another peptide.

PAL-GHK (Palmitoyl Tripeptide-1) Research

Pal-GHK (also called palmitoyl tripeptide-1 and palmitoyl oligopeptide) is a synthetic peptide known for its effects on collagen, skin health, and skin pigment. It is currently under investigation for its ability to boost collagen synthesis in animal models as well as for its ability to stimulate blood vessel growth.
