Mechanism of Action
This peptide functions by signaling endogenous skin repair pathways. Its primary action closely mimics botulinum-like peptides, involving the inhibition of the SNARE complex. This complex is pivotal for the fusion of vesicles and the subsequent release of acetylcholine into the synaptic cleft. By binding to SNARE proteins, the peptide disrupts their interaction, preventing stable complex formation and thereby reducing acetylcholine release. This biochemical interference ultimately weakens facial muscle contractions, leading to a visible smoothing of superficial wrinkles. An additional proposed mechanism includes modulating calcium-dependent pathways crucial for neurotransmitter exocytosis.

Safety Profile
While generally considered safe for topical application, specific data regarding its use during pregnancy and breastfeeding are absent, necessitating professional medical consultation. Although adverse reactions are rare, a preliminary patch test is advised to rule out localized irritation or allergic responses. The Cosmetic Ingredient Review (CIR) has classified data as 'insufficient', and there are no specific SCCS opinions for this exact fusion peptide. Notably, a related component, sh-oligopeptide-1, has faced criticism regarding the scientific rigor of its supporting clinical studies.
