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, Humanin exerts neuroprotective and cytoprotective effects in models of Alzheimer’s disease, ischemia, and metabolic stress, reducing apoptosis and improving cell survival7136141.
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, Humanin is a mitochondrial-derived 24-amino-acid peptide that protects cells against diverse apoptotic insults by interacting with cell-surface cytokine receptor complexes and intracellular targets, thereby activating pro-survival STAT3 and other pathways7136141.
Argireline
Molecular target is the SNARE complex component SNAP-25 rather than a classical receptor; it interferes with SNAP-25 participation in vesicle fusion49

Both peptides fall into a similar broad context as Neuropeptides, although the details of how they are used and discussed still diverge. Their typical research and application settings separate fairly clearly: Argireline is more often discussed in the realm of Dermatology and aesthetics, whereas Humanin is more often associated with the realm of Neurology and brain health, Aging and longevity, and Cardiovascular health. They also influence different molecular systems, with Argireline tracking more closely to SNARE complex while Humanin centers more on GPCR receptor. Argireline has a more synthetic design origin, while Humanin is closer to mitochondrial-encoded background and their development context also differs, with Argireline cosmetic grade while Humanin is in Preclinical development. Argireline incorporates acetylation features that are not part of Humanin, while their sequence patterns also diverge, with Argireline showing protein-mimetic sequence features and Humanin showing alpha-helical domain features.
