Argireline (Acetyl Hexapeptide-8)

SNAP-25 mimetic that interferes with neurotransmitter release at neuromuscular junctions — botox-like expression-line reducer.

Argireline is the original "topical Botox" peptide. It works on the same target as Botox — the SNARE machinery nerves use to fire muscles — but applied to the skin's surface it only mildly dampens the tiny muscle contractions that etch expression lines over time. The effect is real but gradual and far gentler than injections: softening of forehead and crow's-feet lines with daily use, not freezing.
