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 Argireline is a topical cosmetic peptide reported to decrease dynamic wrinkles by partially mimicking the mechanism of botulinum toxin in a non-invasive manner49, MOTS-c improves insulin sensitivity, enhances glycolysis, reduces oxidative stress, and shows protective effects in models of metabolic syndrome, aging, and ischemia-reperfusion injury8135146.
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, MOTS-c is a 16-amino-acid mitochondrial-derived peptide that translocates to the nucleus under metabolic stress and regulates glucose and lipid metabolism largely via activation of AMPK and modulation of mTOR and folate-cycle–linked pathways854140146.
Argireline
Molecular target is the SNARE complex component SNAP-25 rather than a classical receptor; it interferes with SNAP-25 participation in vesicle fusion49

Argireline and MOTS-c are noticeably different, with limited direct overlap in their usual biological context. Their typical research and application settings separate fairly clearly: Argireline is more often discussed in the realm of Dermatology and aesthetics, whereas MOTS-c is more often associated with the realm of Metabolic and endocrine and Aging and longevity. They also influence different molecular systems, with Argireline tracking more closely to SNARE complex while MOTS-c centers more on Mitochondrial membrane. Argireline has a more synthetic design origin, while MOTS-c is closer to mitochondrial-encoded background and their development context also differs, with Argireline cosmetic grade while MOTS-c is in Preclinical development. Argireline incorporates acetylation features that are not part of MOTS-c, while their sequence patterns also diverge, with Argireline showing protein-mimetic sequence features and MOTS-c showing hydrophobic domain features.
