Argireline, also known as acetyl hexapeptide-8, is a neurotransmitter inhibitory peptide with high anti-wrinkle activity and low side effects. Acetylhexapeptide-8 participates in the competition for the position of SNAP-25 in the vesicle complex, thus affecting the formation of the complex. When the vesicle complex is slightly unstable, the vesicles cannot effectively release neurotransmitters, which can weaken muscle contraction and prevent the formation of wrinkles.
