What is SNAP-8?

SNAP-8 is a topical cosmetic peptide sold as a Botox alternative, and the honest summary is that it is completely safe but essentially unproven. Its full name is acetyl octapeptide-3, an eight-amino-acid synthetic peptide that brands market for softening expression wrinkles around the eyes and forehead. The claimed mechanism is plausible by analogy to its better-known hexapeptide cousin argireline, but no independent peer-reviewed study has tested SNAP-8 on its own, and the famous up to 35 percent wrinkle reduction figure is a manufacturer marketing claim rather than a published trial result, per the read-across evidence in Wang et al. 2013.
