Acetyl Tetrapeptide-9 is a synthetic peptide that mimics Lumican's matrikine function regulating fibroblast activities. The ingredient stimulates the skin's natural regeneration mechanisms so that it not only looks young but also feels young. The peptides' sequence is Ac-Gln-Asp-Val-His-OH. The proteoglycans - small protein-sugar complexes - are of central importance for the effective organization of collagen fibres and, thus, the extracellular matrix. Lumican is a proteoglycans that bind to collagen, connecting its molecules, decreasing the gap, and forming functional fibres. Scientific studies showed that the natural synthesis of Lumican declines with age. Acetyl Tetrapeptide-9 leaves a unique anti-ageing effect that uses the metabolism of a specific proteoglycan - Lumican - to improve the skin's firmness and suppleness. Lumican plays a particularly important role: it ensures optimal stability of the extracellular matrix, both by facilitating the synthesis of collagen fibrils and their organization into functional fibre supports.

Acetyl Tetrapeptide-9 is a synthetic peptide made up of the amino acids, aspartic acid, glutamine, histidine and valine. It has the function of optimising collagen fibres and is safe, practical and effective against skin ageing, helping to visibly restore the skin's natural support. Includes a special protein called lumican which helps to keep the skin smooth and firm.
