Comparison

Matrixyl vs Retatrutide

Function

While Matrixyl is a widely used cosmetic peptide with evidence of stimulating extracellular matrix synthesis and reducing wrinkle appearance in skin-care formulations48, Retatrutide is an investigational agent that produces very large body-weight reductions in early trials by simultaneously engaging GLP-1R, GIPR, and GCGR to enhance satiety, energy expenditure, and glycemic control2575.

Mechanism

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, Retatrutide is a triple incretin agonist peptide derived from a GIP backbone and engineered to activate GLP-1, GIP, and glucagon receptors, with non-natural residues and fatty-acid conjugation that confer long half-life and balanced multi-receptor signaling256575.

Length and Sequence

Matrixyl is 5 amino acids long, whereas Retatrutide is longer as it has a length of 39 amino acids. Matrixyl is made up of a sequence of Lysine, Threonine, Threonine, Lysine, Serine. Retatrutide is made up of a sequence of sequence data not available in the current dataset.

Receptor
