SNAP-8
Acetyl Octapeptide-3 studied as a topical cosmetic peptide for expression-line research.
SNAP-8 (Acetyl Octapeptide-3) is the peptide behind a lot of topical anti-wrinkle and Botox-alternative cosmetic research. It is an extended version of the well-known Argireline peptide, studied for how it modulates the neurotransmitter signals at the junction where nerves meet muscle — the mechanism of interest in softening the appearance of expression lines. It is handled as a topical cosmetic research compound.
As a longer relative of Argireline, it is studied for a gentler, topical route into expression-line research.
