What it is
Snap-8 (acetyl octapeptide-3) is a cosmetic peptide marketed as a topical alternative to neuromodulators for expression lines.
Proposed mechanism
It is proposed to interfere with the SNARE complex involved in neurotransmitter release at the neuromuscular junction, mildly reducing muscle contraction — a topical, far weaker analogy to botulinum toxin.1
State of the evidence
Cosmetic/topical marketing data; not a drug.
Regulatory & status
Used as a topical cosmetic ingredient.
