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, Exenatide is used for type 2 diabetes treatment to improve glycemic control and modestly reduce body weight through GLP-1–like insulinotropic and glucagonostatic effects6768.
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, Exenatide is a 39-amino-acid exendin-4 peptide originally isolated from Gila monster venom that acts as a long-acting GLP-1 receptor agonist resistant to DPP-4 degradation67.

Acetyl tetrapeptide-5 and Exenatide are noticeably different, with limited direct overlap in their usual biological context. Their typical research and application settings separate fairly clearly: Acetyl tetrapeptide-5 is more often discussed in the realm of Dermatology and aesthetics, whereas Exenatide is more often associated with the realm of Metabolic and endocrine. They also influence different molecular systems, with Acetyl tetrapeptide-5 tracking more closely to Extracellular matrix proteins while Exenatide centers more on GLP-1 receptor. Acetyl tetrapeptide-5 has a more synthetic design origin, while Exenatide is closer to venom-derived background and their development context also differs, with Acetyl tetrapeptide-5 cosmetic grade while Exenatide is approved. Acetyl tetrapeptide-5 carries acetylation features, while Exenatide instead reflects amidation changes.
