Acetyl Tetrapeptide-11: Texture-Refining Peptide for Epidermal Cohesion
Acetyl Tetrapeptide-11 (CAS 928006-88-6) is a texture-refining tetrapeptide that targets epidermal organization through syndecan-1 proteoglycan synthesis. By strengthening intercellular communication and structural cohesion within the epidermis, this peptide delivers measurable improvements in skin smoothness and uniformity. TCS NEXUS S.L. produces Acetyl Tetrapeptide-11 from our warehouse in Valencia, Spain.
Mechanism of Action
Acetyl Tetrapeptide-11 stimulates keratinocyte production of syndecan-1, a transmembrane heparan sulfate proteoglycan critical to epidermal architecture. Syndecan-1 functions as a co-receptor for multiple growth factors and as an adhesion molecule that organizes the pericellular matrix around keratinocytes. When syndecan-1 levels decline with age or UV exposure, the epidermis loses its organized stratification, resulting in rough texture, visible pores, and uneven surface topography. By restoring syndecan-1 expression, Acetyl Tetrapeptide-11 re-establishes proper keratinocyte differentiation patterns and tight junction formation across all epidermal layers.
Clinical Performance Data
Clinical evaluation of Acetyl Tetrapeptide-11 at 50ppm in a daily-use moisturizer demonstrated a 23% improvement in skin smoothness parameters over 56 days, measured by optical profilometry. Roughness index (Ra) decreased significantly from baseline by day 28, with continued improvement through the study endpoint. Corneocyte cohesion, assessed by tape-stripping desquamation analysis, improved by 19%, confirming the peptide effect on intercellular adhesion within the stratum corneum. Panelists reported visible refinement in pore appearance and overall skin texture uniformity.
Formulation Parameters
Recommended use level for Acetyl Tetrapeptide-11 is 30-100ppm in finished products. The peptide is water-soluble and maintains stability at pH 4.5-6.5. It incorporates easily into lightweight serums, gel creams, toners, and essence formulations where texture refinement is the primary claim. Cosmetic chemists working on pore-minimizing or skin-smoothing products frequently pair Acetyl Tetrapeptide-11 with niacinamide or zinc PCA for complementary mechanisms addressing sebum regulation alongside epidermal restructuring.
