Cosmetic peptides · SNAP-25-mimicking cosmetic hexapeptide.
Argireline is acetyl hexapeptide-8, a cosmetic peptide used in wrinkle serums and creams. Some small trials found smoother lines; others found no added benefit. A “10% Argireline” formula can contain a diluted ingredient solution, so it does not mean 10% pure peptide. Irritation can occur, and topical evidence does not establish injection safety.
- In a small trial on eye-area wrinkles, more people improved with it than with a placebo cream. (Studied in a trial)
- In a trial, a dissolving microneedle patch with it improved one eye-wrinkle measure more than a plain patch. (Studied in a trial)
- Some small studies found smoother lines, though others found no added benefit. (Studied in a trial)
- Some users report smoother frown lines with daily use; another reported no real change. (Reported by users)
