Science
Mechanism of Action
This peptide functions as a competitive antagonist to acetylcholine receptors, intercepting nerve signals at the post-synaptic membrane. By inhibiting the muscle contractions that are the root cause of dynamic wrinkles, Pentapeptide-3 promotes relaxation of facial muscles and leads to a smoother skin surface.

Safety
Safety Profile
Pentapeptide-3 demonstrates a favorable safety profile for topical cosmetic applications, with infrequent occurrences of allergic reactions or irritation. While generally considered safe, individuals with highly sensitive skin may benefit from patch testing. It is crucial to distinguish Pentapeptide-3 (Vialox) from other pentapeptides, such as Myristoyl Pentapeptide-4, Palmitoyl Pentapeptide-4, and Pentapeptide-4, which possess different structures and have received separate safety evaluations by the CIR Expert Panel.
