Acetyl Hexapeptide (also known as Acetyl Hexapeptide-8 or Argireline) is a synthetic peptide that works topically to reduce the appearance of expression lines by limiting facial muscle contraction at the neuromuscular junction. It is commonly marketed as a topical alternative to injectable neuromodulators for fine lines and wrinkles.
