Acetyl Octapeptide-3 (SNAP-8)
Also known as: SNAP-8 · snap 8 · acetyl glutamyl heptapeptide-3
An eight-amino-acid cosmetic peptide that extends Argireline, designed to soften expression lines by targeting the SNARE complex.
SNAP-8 adds two amino acids to the Argireline sequence. Published human studies test it inside multi-ingredient products, including Korean hyaluronic-acid microneedle patches, so its stand-alone effect has not been isolated.
