Alpha Acetyl Tetrapeptide 5
What is Alpha Acetyl Tetrapeptide 5?
Alpha Acetyl Tetrapeptide-5 is a synthetic tetrapeptide composed of acetylated amino acids designed to target puffiness and under-eye bags in skincare formulations. It works by inhibiting angiotensin-converting enzyme (ACE), which reduces fluid accumulation and inflammation around the delicate eye area. Commonly used in eye creams and serums at concentrations of 0.5-5%, it helps improve skin firmness and reduce the appearance of dark circles.
