Research record
Overview
Compound name: SNAP-8
Alternative name: Acetyl Octapeptide-3
Compound classification: Synthetic neurocosmetic peptide
Brief factual description:
SNAP-8 (Acetyl Octapeptide-3) is an eight–amino acid synthetic peptide developed as a topical cosmetic active. It is designed to mimic part of SNAP-25, a protein involved in neurotransmitter release, and is researched for its ability to reduce facial muscle contraction associated with expression wrinkles.
Mechanism of Action
Primary biological targets: SNAP-25–associated neurotransmitter release pathways
Affected systems: Neuromuscular (localized, topical application)
Core mechanisms
Competitive interference with SNAP-25 complex formation
Downstream effects
Reduced acetylcholine release at neuromuscular junctions (localized)
Decreased facial muscle micro-contraction
Softening of expression lines
SNAP-8 is often described as a “Botox-like” cosmetic peptide, though its effects are significantly milder and limited to topical activity.
