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 FOXO4-DRI acts as a senolytic in preclinical models by promoting apoptosis of senescent cells, improving tissue function and healthspan measures in aged animals38, Matrixyl is a widely used cosmetic peptide with evidence of stimulating extracellular matrix synthesis and reducing wrinkle appearance in skin-care formulations48.
While FOXO4-DRI works as 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, Matrixyl is a palmitoylated pentapeptide, Pal-Lys-Thr-Thr-Lys-Ser (Pal-KTTKS), that acts as a matrikine, signaling to dermal fibroblasts to increase production of collagen, elastin, fibronectin, and other ECM components4858.

FOXO4-DRI and Matrixyl are noticeably different, with limited direct overlap in their usual biological context. Their typical research and application settings separate fairly clearly: FOXO4-DRI is more often discussed in the realm of Aging and longevity, whereas Matrixyl is more often associated with the realm of Dermatology and aesthetics. Their biological logic is quite different: FOXO4-DRI is a protein interaction inhibitor, whereas Matrixyl is a matrix remodeling modulator. Both are synthetic in origin and their development context also differs, with FOXO4-DRI in Preclinical development while Matrixyl is cosmetic grade. FOXO4-DRI takes the form of a linear peptide, whereas Matrixyl is closer to a peptide conjugate, while FOXO4-DRI carries retro-inverso isomerization features, while Matrixyl instead reflects palmitoylation changes.
