Argireline
Topical muscle-relaxing cosmetic peptide.
What it is
Argireline (acetyl hexapeptide-8, also called acetyl hexapeptide-3) is a synthetic six-amino-acid cosmetic peptide marketed as a topical alternative to botulinum toxin for fine lines and wrinkles. It is widely incorporated into “anti-aging” skincare products.
Mechanism of action
Argireline is hypothesized to inhibit catecholamine release at neuromuscular junctions through interference with SNARE protein complex formation. The proposed effect is reduced facial muscle contraction with topical application, potentially reducing the appearance of dynamic wrinkles. The actual clinical effect is significantly smaller than that of intramuscular botulinum toxin.
Use as cosmetic ingredient
Formulated into topical skincare products at typical concentrations of 5–10%. Available widely as cosmetic products.
