A-Z — Argireline

Acetyl Hexapeptide-3, also known as Acetyl Hexapeptide-8 or Argireline or peptide K8 — A synthetically produced neuropeptide which is often used as a muscle relaxer. It blocks signals from the nerves to the muscle, temporarily stopping the release of neurotransmitters responsible for muscle contractions that can lead to fine lines and wrinkles formation, while also helping reduce the appearance of existing wrinkles. The affected muscle can no longer contract. This reduction in intensity of facial muscle contractions reduces and prevents the formation of dynamic wrinkles that make your skin look aged. In essence, it is a shortened peptide sequence of Botox™...

Peptides — short polymers formed by linking amino acids. When such an amino acid chain is small, the molecule is called a peptide. When it is larger, it is called a polypeptide. Proteins are polypeptide molecules. While proteins cannot penetrate the skin, smaller peptides can be absorbed. The ability to link different numbers of amino acids, thereby forming different peptides and polypeptides, gives these ingredients a variety of beneficial properties when incorporated into cosmetic products. These benefits range from increased skin elasticity and smoothness to improvements in the appearance of wrinkles, a reduction of inflammation, and tissue repair. There are...
