Palmitoyl Tetrapeptide-3

Description:
Palmitoyl Tetrapeptide-3, also known as Rigin, is a synthetic peptide corresponding to the 341-344 amino acid sequence of human immunoglobulin G heavy chain. It is designed to stimulate phagocytosis and enhance skin repair by boosting the expression of Granulocyte Chemotactic Protein-2 (GCP-2), which recruits cells to damaged areas for cleansing and repair. It is commonly used in anti-aging and skin-soothing cosmetics due to its ability to reduce inflammation and support skin barrier function.
