Also called Acetyl octapeptide-3, Acetyl glutamyl heptapeptide-1

An eight-amino-acid cosmetic peptide extended from Argireline. It interferes with the SNARE protein complex that nerve endings use to release acetylcholine, softening the muscle contractions that etch expression lines — the same pathway botulinum toxin blocks, far more weakly and from the outside.

Why people take it

Expression lines and wrinklesTopical alternative to injectables

What studies report

In practice Unapproved use

Reported real-world use, not evidence and not a recommendation.

Worth knowing: Most of the efficacy data comes from the companies selling it, and a large peptide struggles to penetrate skin to reach nerve endings at all. Effects, where present, are modest.

Status: Used in topical cosmetics. Not a medicine.
