Description
Acetyl Tetrapeptide-5, marketed as Eyeseryl, is the gold-standard peptide for eye contour care formulations. It reduces under-eye puffiness, dark circles, and edema through angiotensin-converting enzyme (ACE) inhibition, which improves microcirculation and lymphatic drainage in the delicate periorbital area.
By reducing capillary permeability and fluid accumulation, Eyeseryl provides visible de-puffing effects within hours of initial application. Long-term use also improves periorbital skin elasticity and reduces the appearance of dark circles through enhanced tissue quality.
Highly water-soluble and integrates seamlessly into gels, serums, creams, and eye patches. Recommended use concentration ranges from 0.001% to 0.01%. Formulation compatibility is excellent, with stability across a broad pH range (4-8).
