Mechanism	Leuphasyl is a neurotransmitter-inhibiting peptide that reduces muscle contraction by mimicking enkephalins. It decreases acetylcholine secretion and is synergistic with Argireline for anti-wrinkle effects.	Syn-Ake is a synthetic peptide mimicking snake venom that relaxes facial muscles and reduces wrinkle depth. It is a safe, topical alternative to Botox for smoothing expression lines.
