Acetyl hexapeptide-3 or acetyl hexapeptide-8 (sources differ) is a synthetic anti-wrinkle cosmetics ingredient. It is a peptide which is a fragment of SNAP-25, a substrate of Botulinum toxin (Botox). Acetyl hexapeptide-8 is marketed as Argireline by the Barcelona-based research laboratory Lipotec.^[1]

Overview and common uses

Argireline is used in attempts to decrease the visible effects of aging by reducing the deep wrinkles and lines that occur around the forehead and eyes.^[1][2]

Chemically, when applied as a solution to specific areas of the face, Argireline inhibits the reactions that cause muscles to move or contract^[1] – for example when forming facial expressions such as smiling or frowning.

Cosmetic studies

Both in vitro (outside a living organism) and in vivo (using a living organism) tests have been carried out on Argireline, but double-blind clinical trials results have not been published.

Safety research

Argireline has been developed relatively recently and therefore reports on its long-term use have not yet been produced.

Chemistry

Argireline is the hexapeptide with the sequence Ac-Glu-Glu-Met-Gln-Arg-Arg-NH₂.^[1]
