What is Eyeseryl Peptide?
Xi'an Faithful BioTech Co., Ltd. is situated in Xi'an, the birthplace of the ancient Silk Road. Leveraging the city's mature logistics network and abundant fine chemical industrial resources, our enterprise has grown into an integrated fine chemical provider that delivers products to global partners. Eyeseryl Peptide, CAS No. 820959-17-9, is a widely recognized water-soluble synthetic active peptide in skincare formulations, suitable for the delicate skin around the eyes. This ingredient helps optimize microcirculation around the eyes, soothes localized swelling, improves morning puffiness, gently corrects dark circles, and soothes tired appearance. It also slows down the glycation process within the skin, protects collagen and elastin fibers, maintains the skin's natural suppleness, and improves visual concerns such as sagging and drooping contours around the eyes, resulting in a firmer and smoother eye area.
Application of Eyeseryl Peptide
Acetyl Tetrapeptide-5, a water-soluble active peptide, is primarily used in various topical skincare formulations, especially suitable for eye care products. It is commonly found in eye creams, eye serums, eye masks, and firming gels. It can be combined with hyaluronic acid, plant extracts, and other active peptides to synergistically condition the skin, exhibiting good formula compatibility. It is recommended to add it during the cooling phase of the formula to ensure activity stability. In addition to eye care, it can also be used in facial firming serums to help improve puffiness and dullness caused by poor skin circulation, and maintain the skin's fiber suppleness.

Mechanism of action of Acetyl Tetrapeptide-5
It regulates local microcirculation, reduces capillary permeability, decreases tissue fluid accumulation, alleviates skin puffiness, and improves the appearance of puffiness around the eyes.
It intervenes in the angiotensin-converting enzyme pathway in the body, soothing dullness caused by circulatory stagnation and improving the visual appearance of bluish-toned dullness.
It slows down the process of glycation in the skin, reduces abnormal fibrin cross-linking, protects the structure of collagen and elastin fibers, and maintains skin suppleness.
It soothes the tightness and sagging appearance caused by tired skin, helps maintain the firmness of skin contours, and long-term effects help improve signs of sagging around the eyes.
