Argireline, also known as acetyl hexapeptide-8, is a synthetic peptide commonly used in skincare and anti-aging products. It works by inhibiting the release of neurotransmitters that control muscle contractions, particularly those responsible for facial expressions. By reducing the intensity and frequency of these muscle movements, argireline aims to temporarily smooth the appearance of wrinkles and fine lines caused by repetitive facial expressions. This ingredient is often sought after for its potential to provide a more youthful and relaxed appearance to the skin, targeting areas such as forehead lines, crow's feet, and expression lines.
