Comparison
While Argireline is a topical cosmetic peptide reported to decrease dynamic wrinkles by partially mimicking the mechanism of botulinum toxin in a non-invasive manner49, Matrixyl is a widely used cosmetic peptide with evidence of stimulating extracellular matrix synthesis and reducing wrinkle appearance in skin-care formulations48.
While Argireline works as acetyl hexapeptide-8 (Ac-Glu-Glu-Met-Gln-Arg-Arg-NH2), a SNAP-25–mimetic peptide that competitively inhibits SNARE complex assembly, reducing acetylcholine release at neuromuscular junctions and attenuating facial muscle contraction4959, Matrixyl is a palmitoylated pentapeptide, Pal-Lys-Thr-Thr-Lys-Ser (Pal-KTTKS), that acts as a matrikine, signaling to dermal fibroblasts to increase production of collagen, elastin, fibronectin, and other ECM components4858.
Argireline is 6 amino acids long, whereas Matrixyl is shorter as it has a length of 5 amino acids. Argireline is made up of a sequence of Glutamic acid, Glutamic acid, Methionine, Glutamine, Arginine, Arginine. Matrixyl is made up of a sequence of Lysine, Threonine, Threonine, Lysine, Serine.
Argireline
Molecular target is the SNARE complex component SNAP-25 rather than a classical receptor; it interferes with SNAP-25 participation in vesicle fusion49
