Written by Peptide Association Editorial TeamMedically reviewed by Ian Justl Ellis, MD, CPTLast reviewed Editorial policy

Overview

Acetyl Tetrapeptide-5 is a synthetic tetrapeptide modified with an acetyl group to improve stability and cellular uptake. The peptide is proposed to reduce periorbital edema by modulating capillary permeability and enhancing lymphatic drainage, potentially through downregulation of pro-inflammatory cytokines such as interleukin-1.

Mechanism of Action

Its application is focused on reduction of under-eye puffiness and fluid accumulation.

Research Summary & Key Findings

In vitro studies on endothelial cell monolayers have demonstrated reduced permeability and decreased inflammatory marker expression. A small clinical trial reported subjective improvement in periorbital edema after four weeks, though the study lacked control groups and has not been reproduced in major peer-reviewed dermatology journals.
