Acetyl Hexapeptide-3 (Argireline): Comprehensive Guide to Benefits, Mechanisms, and Research
Acetyl Hexapeptide-3 Argireline - widely recognized by its trade name Argireline and now officially designated Acetyl Hexapeptide-8 in INCI nomenclature - is a synthetic six-amino-acid peptide used in topical skincare formulations to reduce the appearance of dynamic expression wrinkles. It works by partially disrupting the SNARE protein complex at facial neuromuscular junctions, reducing the force and frequency of the muscle contractions that deepen crow's-feet, forehead lines, and glabellar lines over time. This guide covers what Acetyl Hexapeptide-3 does, how it works, what the clinical evidence shows, how to interpret dosing and concentration data, its safety profile, and how it compares to botulinum toxin and other anti-aging approaches.
