Acetyl Tetrapeptide-5

Synonyms: Acetyl Tetrapeptide-5, Acetyl Tetrapeptide-5 (CAS 820959-17-9), Eyeseryl, Acetyl tetrapeptide-9, Acetyl Tetrapeptide-5 (INCI name)

In the competitive landscape of peptide-based actives, Acetyl Tetrapeptide-5 has carved out a niche as a targeted solution for addressing periorbital concerns. Formulators increasingly turn to this peptide to support the appearance of firmer, more contoured skin around the delicate eye area, a key battleground in the anti-aging market.

Acetyl Tetrapeptide-5 is a synthetic peptide composed of four amino acids, specifically designed to mimic the decongesting and firming effects of natural proteins. It is often referred to as Eyeseryl in commercial applications, reflecting its primary use in eye contour cosmetics.

This peptide is known for its ability to reduce the appearance of puffiness and dark circles by improving microcirculation and strengthening the capillary walls. With a purity of ≥98% (HPLC), it is a reliable choice for cosmetic formulations targeting eye care and firming.

Product Overview & Composition

Acetyl Tetrapeptide-5 is a tetrapeptide with the sequence Acetyl-Arg-Ser-Lys-Glu-OH. Its structure allows it to interact with the skin’s extracellular matrix, promoting a more supple and toned appearance. The acetylation on the N-terminus enhances its stability and bioavailability, making it a robust ingredient for various cosmetic matrices.

This peptide is water-soluble, which simplifies incorporation into serums, creams, and gels. Its mechanism of action involves inhibiting the formation of advanced glycation end-products (AGEs) and supporting the integrity of the dermal matrix, which contributes to a visible improvement in skin firmness and resilience.
