Acetyl tetrapeptide-5
is used in cosmetic eye formulations to decrease puffiness, eye bags, and dark circles by reducing edema and protecting proteins such as SOD from glycation
Alanine
Ala / A · hydrophobic residue · neutral charge
AOD-9604
is studied as an anti-obesity peptide that can reduce weight gain and increase fat oxidation in obese animal models with generally neutral effects on IGF-1 and glucose metabolism in early human trials
Arginine
Arg / R · basic residue · positive charge
Argireline
is a topical cosmetic peptide reported to decrease dynamic wrinkles by partially mimicking the mechanism of botulinum toxin in a non-invasive manner
Asparagine
Asn / N · polar residue · neutral charge
Aspartic acid
Asp / D · acidic residue · negative charge
BPC-157
is investigated for accelerating healing of gastrointestinal mucosa, tendons, ligaments, bone, and nervous tissue in preclinical models, with anti-inflammatory and pro-angiogenic effects
Comparison
While Matrixyl is a widely used cosmetic peptide with evidence of stimulating extracellular matrix synthesis and reducing wrinkle appearance in skin-care formulations48, Semaglutide is approved for type 2 diabetes and chronic weight management, significantly lowering HbA1c and body weight by modulating incretin pathways232480.
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, Semaglutide is a modified GLP-1(7–37) analog with three key changes—Ala8→Aib, Lys26 acylated with a C18 fatty diacid, and Lys34→Arg—resulting in a long-acting GLP-1 receptor agonist that enhances glucose-dependent insulin secretion, suppresses glucagon, slows gastric emptying, and reduces appetite23647480.

Matrixyl and Semaglutide are noticeably different, with limited direct overlap in their usual biological context. Their typical research and application settings separate fairly clearly: Matrixyl is more often discussed in the realm of Dermatology and aesthetics, whereas Semaglutide is more often associated with the realm of Metabolic and endocrine and Cardiovascular health. They also influence different molecular systems, with Matrixyl tracking more closely to Extracellular matrix proteins while Semaglutide centers more on GLP-1 receptor. Matrixyl has a more synthetic design origin, while Semaglutide is closer to synthetic analog background and their development context also differs, with Matrixyl cosmetic grade while Semaglutide is approved. Matrixyl carries palmitoylation features, while Semaglutide instead reflects lipidation changes, while their sequence patterns also diverge, with Matrixyl showing protein-mimetic sequence features and Semaglutide showing alpha-helical domain features.
