Marketed as a 'Botox-alternative' topical. Mimics the N-terminal domain of SNAP-25, competing with the SNARE complex at the neuromuscular junction — theoretically reducing acetylcholine release and muscle contraction that causes expression lines. Topical penetration is limited; clinical efficacy data weak vs injectable botulinum toxin.
