Snap-8
Acetyl Octapeptide-3
An advanced version of Argireline with 8 amino acids instead of 6. Targets expression wrinkles with a more complete mechanism for inhibiting muscle micro-contractions in the face.
Also known as: Acetyl Glutamyl Heptapeptide-1
- Status
- Snap-8 is used as a cosmetic or over-the-counter ingredient, not as an approved drug.
- Evidence
- Early human data. Only small or early-phase studies in people so far.
- Half-life
- N/A (topical, continuous use)
- How it's taken
- Topical serum or cream
- Mechanism
- Cosmetic / topical
- Pathways
- Neuromuscular Junction
How Snap-8 works
Works similarly to Argireline but targets additional components of the SNARE complex. The extra amino acids give it a broader inhibitory effect on the neuromuscular signals that create expression lines.
What research has looked at
- Enhanced wrinkle reduction vs. Argireline
- Targets deeper expression lines
- Non-invasive and needle-free
- Compatible with other skincare actives
- Well-tolerated for daily use
Evidence level: Early human data. Only small or early-phase studies in people so far. These are areas studied or reported, not promised effects.
Reported side effects and risks
- Mild irritation in sensitive skin
- Results vary by individual
- Requires consistent daily application
- Modest effects compared to injectables
- Limited independent clinical trials
