SNAP-8
An eight-amino-acid peptide extending the sequence of Argireline, developed as a topical cosmetic ingredient.
Available in the catalogue
Supplied as research material. Sizes and pricing are on the product page. Availability is not a statement about what a compound does.
What is being investigated
Directions the published work points at, and how far each has actually got. These are open questions, not established effects: most of what looks promising in cells does not replicate in animals, and most of what works in animals does not work in people. Nothing here is a claim about what this compound does for anyone.
- Appearance of expression lines
What the cosmetic studies measured, in topical formulations. Those studies are small, generally run by the ingredient's own suppliers, and are a weak evidence base by the standards of anything else on this page.
Human trials
- Competing for a place in the SNARE complex
The proposed mechanism: modelled on the end of SNAP-25, competing for assembly and so reducing the efficiency of neurotransmitter release. Aimed at the same biology as botulinum toxin, from the outside and far more weakly.
Cell and tissue studies
- Whether it reaches anything through skin
The open question under all of the above, and it is a formulation question rather than one about the molecule: an eight-residue peptide crossing the stratum corneum in useful quantity is not something to assume.

A topical cosmetic peptide with a coherent SNARE mechanism and almost no independent indexed literature. The absence of published work is the honest headline.
- How to store research peptides
Lyophilised peptides at -20°C, reconstituted at 2–8°C, ambient in transit. Why the dry cake tolerates shipping, and what actually degrades a vial.
