Overview

A synthetic eight-amino-acid peptide sold as a topical route to softening expression lines, and closely related in concept to acetyl hexapeptide-8. It is meant to interfere with the signalling that drives repeated muscle contraction.

Who it's for

Forehead and eye-area products aimed at movement lines, for people avoiding injectables.

Cautions
