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, FOXO4-DRI acts as a senolytic in preclinical models by promoting apoptosis of senescent cells, improving tissue function and healthspan measures in aged animals38.
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, FOXO4-DRI is a D-retro-inverso peptide derived from a FOXO4 region that competes with endogenous FOXO4 for binding to p53, thereby releasing p53 to trigger apoptosis selectively in senescent cells38.

FOXO4-DRI
FOXO4
Acetyl tetrapeptide-5 and FOXO4-DRI 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 FOXO4-DRI is more often associated with the realm of Aging and longevity. Their biological logic is quite different: Acetyl tetrapeptide-5 is a signaling modulator, whereas FOXO4-DRI is a protein interaction inhibitor. Both are synthetic in origin and their development context also differs, with Acetyl tetrapeptide-5 cosmetic grade while FOXO4-DRI is in Preclinical development. Acetyl tetrapeptide-5 carries acetylation features, while FOXO4-DRI instead reflects retro-inverso isomerization changes.
