Though its name does not reveal it, Mu-Conotoxin Cniiic is a 22 amino acid peptide molecule that belongs to the "Botox-in-a-jar" type of topical muscle relaxers. (If you are new to these types of molecules, we wrote more about it at Argireline.)
It is a biomimetic peptide, meaning that it tries to copy the behavior of the natural peptide found in the venomous marine cone snail called Conus consors. Biologically speaking, the molecule acts as a modulator of the neuromuscular transmission that translates to being an instant line relaxer when it comes to cosmetics. According to the manufacturers in-vivo (made on people) study, a single application with 3% XEP-018 on 33 people results in a visible and significant reduction of wrinkle depth and rugosity 2 hours after application. Sounds pretty good.
Show me some proof
