Hexapeptide-9
Hexapeptide-9 is a synthetic peptide composed of glutamine, glycine, and proline residues. It is classified as a skin conditioning and cell-communicating ingredient. According to its manufacturer, it is designed to visibly reduce the length and depth of wrinkles. In vitro studies cited by the manufacturer suggest it enhances epidermal regeneration and the synthesis of collagen type I and III, as well as other important skin proteins.
Hexapeptide-9 is claimed to visibly reduce wrinkle length and depth. In vitro data from the manufacturer indicates it may support epidermal regeneration and stimulate collagen type I and III synthesis. Evidence is currently limited to lab-based (in vitro) studies and manufacturer claims rather than clinical trials on human subjects.
