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 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 glycation51150159154, Humanin exerts neuroprotective and cytoprotective effects in models of Alzheimer’s disease, ischemia, and metabolic stress, reducing apoptosis and improving cell survival7136141.
While Acetyl tetrapeptide-5 works as a synthetic tetrapeptide, Ac-βAla-His-Ser-His (Eyeseryl), with reported ACE-1 inhibition and anti-glycation activity, proposed to improve microcirculation and reduce capillary permeability and fluid accumulation in periorbital tissues51150159157, 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.

The clearest overlap between Acetyl tetrapeptide-5 and Humanin is that both converge around Signaling modulator. Their typical research and application settings separate fairly clearly: Acetyl tetrapeptide-5 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. Both appear to work through Signaling modulator, but the functional emphasis still separates, with Acetyl tetrapeptide-5 leaning toward Anti-inflammatory and Humanin leaning toward Neuroprotection and cognition and Mitochondrial function modulation. Acetyl tetrapeptide-5 has a more synthetic design origin, while Humanin is closer to mitochondrial-encoded background and their development context also differs, with Acetyl tetrapeptide-5 cosmetic grade while Humanin is in Preclinical development. Acetyl tetrapeptide-5 incorporates acetylation features that are not part of Humanin.
