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

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 Hexarelin is investigated for effects on GH secretion, cardiac protection, and muscle metabolism, with higher GH secretory potency than earlier GHRPs1929, Matrixyl is a widely used cosmetic peptide with evidence of stimulating extracellular matrix synthesis and reducing wrinkle appearance in skin-care formulations48.
While Hexarelin works as a potent synthetic hexapeptide (examorelin) that agonizes GHSR-1a to stimulate GH release and also binds CD36, influencing cardiovascular and metabolic pathways19212996, 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.

Hexarelin and Matrixyl are noticeably different, with limited direct overlap in their usual biological context. Their typical research and application settings separate fairly clearly: Hexarelin is more often discussed in the realm of Metabolic and endocrine and Cardiovascular health, whereas Matrixyl is more often associated with the realm of Dermatology and aesthetics. They also influence different molecular systems, with Hexarelin tracking more closely to Ghrelin receptor while Matrixyl centers more on Extracellular matrix proteins. Both are synthetic in origin and their development context also differs, with Hexarelin in Preclinical development while Matrixyl is cosmetic grade. Hexarelin takes the form of a linear peptide, whereas Matrixyl is closer to a peptide conjugate, while Hexarelin carries d-amino acid substitution and amidation features, while Matrixyl instead reflects palmitoylation changes.
