Acetyl Tetrapeptide-5

INCI: Acetyl Tetrapeptide-5

Acetyl Tetrapeptide-5, marketed under the trade name Eyeseryl, is a synthetic four-amino-acid peptide created through acetylation of tetrapeptide-5. It functions as both a cell-communicating ingredient and a humectant. It is designed to reduce under-eye puffiness through anti-oedema and anti-glycation mechanisms, targeting water accumulation that causes puffy eye bags. A manufacturer study of 20 volunteers using 10% Eyeseryl showed 70% improvement by day 15 and 95% by day 60.
