Comparison
While Matrixyl is a widely used cosmetic peptide with evidence of stimulating extracellular matrix synthesis and reducing wrinkle appearance in skin-care formulations48, Setmelanotide is approved for chronic weight management in patients with POMC, PCSK1, LEPR deficiencies and Bardet–Biedl syndrome by reducing hunger and promoting weight loss92.
While Matrixyl works as 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, Setmelanotide is a potent synthetic melanocortin-4 receptor (MC4R) agonist derived from a POMC/α-MSH–related sequence that restores downstream MC4R signaling in genetic obesity syndromes3192100.
Matrixyl is 5 amino acids long, whereas Setmelanotide is shorter as it has a length of amino acids. Matrixyl is made up of a sequence of Lysine, Threonine, Threonine, Lysine, Serine. Setmelanotide is made up of a sequence of sequence data not available in the current dataset.
