Acetyl Tetrapeptide-5
Brief Introduction:
Acetyl tetrapeptide-5 is a small molecule polypeptide that mainly reduces skin puffiness by changing the microcirculation of regional skin and changing the osmotic pressure of liquid, and is used to remove eye bags and dark circles.
Sequence:
Ac-β-Ala-His-Ser-His-OH

Mechanism of Action:
1. Improve the microcirculation of eye skin by inhibiting angiotensin I converting enzyme.
2. Increase the activity of SOD, inhibit its glycosylation, prevent protein cross-linking, and improve skin elasticity.
3. Reduce the permeability of blood vessels and reduce water leakage.
