Acetyl tetrapeptisde-5 is a known humectant or hydroscopic moisturizer which helps reduce eye puffiness, improve skin elasticity and overall smoothness. Acetyl tetrapeptide-5 has been shown to reduce puffiness and swelling by changing the micro-circulation in the skin in this area, making it less permeable to fluid,regular use of 0.001% Eyeseryl can reduce the leaking of interstitial fluid into the eye by up to 50% - meaning your eyes have far less swelling and puffing.

Science has proven that peptides can help manage wrinkles in your skin and reverse the signs of aging.
Human skin is comprised mostly of collagen. Collagen is a protein comprised of long segments of amino acids arranged like a chain. Collagen provides a foundation and thickness for skin.
Women under 30 have ample collagen, which results in smooth, tight skin.
The rest of us have less collagen - skin tends to be thinner, revealing more wrinkles.
When collagen breaks down, short segments of amino acids are formed. These are the tiny proteins and active molecules known as peptides. Peptides in skin care can provide significant anti-aging benefits.
