Marketed as "Botox in a bottle" — works via muscle relaxation, not collagen. Evidence is modest but real at proper concentrations.

Deep Dive
Argireline mimics the N-terminus of SNAP-25, partially inhibiting neurotransmitter release at muscle-skin junctions. Theoretical mechanism: relax tiny facial muscles, reduce expression lines. Some peer-reviewed clinical studies show modest reduction in crow's feet at 10% concentration over 30 days. Not a Botox replacement, but useful as a gentle anti-aging assist. Often stacked with Matrixyl for compound benefit.
