## Mechanism
An elongation of the better-known Argireline (Acetyl Hexapeptide-3). Research suggests it modulates SNARE complex formation, reducing the muscle contractions that drive expression lines in topical cosmetic studies.

## Research areas
- Expression-line depth (forehead, crow's feet)
- Skin smoothness endpoints

## Common research protocols
- Topical cosmetic use: Used at 5–10% in serums and creams in cosmetic research.

## Study summaries
- "Acetyl octapeptide-3 and expression wrinkles" — International Journal of Cosmetic Science (2013): Reported reduction in wrinkle depth versus placebo in topical trial.

## Considerations
- Topical-only application is well tolerated.
- Effects are modest compared to neurotoxin injectables.
