Reference entry · Cosmetic octapeptide
Snap-8
Also known as: Acetyl octapeptide-3 · SNAP-25 mimetic octapeptide
- Class
- Cosmetic octapeptide
- Size
- 8 amino acids
- Primary targets (literature)
- SNAP-25 interaction literature; neuromuscular junction models
- Regulatory context
- Cosmetic ingredient in many jurisdictions — not an FDA-approved injectable drug. Catalog Snap-8 is RUO material.
Overview
Snap-8 is an acetylated octapeptide studied in cosmetic science as a SNAP-25–related neuromuscular signaling modulator in topical formulation research. Evidence is predominantly in vitro and short-term cosmetic studies.
Mechanism in research literature
Literature proposes interference with SNARE complex assembly in muscle contraction models, framed as a milder cosmetic analog to botulinum-toxin pathway research — not equivalent pharmacology.
Common research focus areas
- In vitro muscle contraction and SNAP-25 assays
- Topical formulation and penetration research
- Cosmetic vs. pharmaceutical evidence distinction
- Acetylated octapeptide sequence confirmation
