Acetyl Octapeptide-3 / SNAP-8

Extended-sequence relative of Argireline with the same SNARE-targeting mechanism.

SNAP-8 is Argireline's longer cousin — an extended sequence that targets the same nerve-to-muscle signalling but is generally considered a bit more effective at relaxing expression lines. It's the pick when you want a stronger topical "muscle-relaxing" peptide, and it's often layered with Argireline in the same serum.
