SNAP-8 (Acetyl Octapeptide-3)
Also known as SNAP-8, Acetyl Octapeptide-3, Acetyl Octapeptide-1
INCI name · Acetyl Octapeptide-3
An extended-sequence relative of Argireline — used to support the appearance of a smoother, more relaxed-looking surface where fine expression lines gather. For external cosmetic use only.
SNAP-8 is what you get when the Argireline idea is stretched a little longer. On a label it's Acetyl Octapeptide-3 — an eight-amino-acid peptide, two residues longer than the classic hexapeptide — designed for the same expression-area job.
It's the choice for people who like the expression-line category and want to try the longer-chain cousin. As with everything in this store, the framing is cosmetic and about appearance only.
How SNAP-8 relates to Argireline
Argireline is a hexapeptide (six amino acids); SNAP-8 is an octapeptide (eight). They belong to the same expression-area family and are used for the same cosmetic purpose — helping the busiest zones of the face look smoother and more relaxed in appearance.
The extra length is the whole distinction of SNAP-8; think of it as the extended-sequence sibling rather than a different category.
Where it shines on the shelf
SNAP-8 is a lightweight leave-on peptide that supports the appearance of a smoother, more relaxed-looking surface around the forehead and eyes. It layers cleanly under moisturizer and is gentle enough for daily wear.
Some people alternate it with Argireline, others pick a single favorite. It pairs naturally with the eye serum and with the firming peptides used elsewhere in a routine.
How to use it
External use only. Pat a few drops over expression areas morning and evening before moisturizer, keeping clear of the immediate lash line. Patch-test on the inner arm before first use and discontinue if irritation occurs. Store cool and out of direct sun.
Common questions
It appears as Acetyl Octapeptide-3 — an acetyl-capped eight-amino-acid peptide, the extended-sequence relative of Argireline (Acetyl Hexapeptide-8).
It's not a matter of strength — it's a longer-chain relative in the same expression-area family. Choice usually comes down to preference; some people alternate the two.
