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, KPV is investigated as an anti-inflammatory and barrier-protective agent in skin and mucosal models, reducing pro-inflammatory cytokines and promoting tissue repair684.
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, KPV is the C-terminal Lys-Pro-Val tripeptide fragment of α-MSH, which exerts potent anti-inflammatory effects largely via inhibition of NF-κB signaling and modulation of cytokine expression, with many actions independent of classical melanocortin receptor activation684.
Acetyl tetrapeptide-5 is 4 amino acids long, whereas KPV is shorter as it has a length of 3 amino acids. Acetyl tetrapeptide-5 is made up of a sequence of βAla, Histidine, Serine, Histidine. KPV is made up of a sequence of Lysine, Proline, Valine.
