Acetyl Tetrapeptide-9
Laminin-stimulator for the dermo-epidermal junction — acetyl tetrapeptide-9 restores the "glue" between the epidermis and dermis, increases tone and lifting effect. One of the few peptides focused on the basement membrane.
What is it?
Acetyl Tetrapeptide-9 — an acetylated tetrapeptide (LNKL or other sequence depending on the manufacturer). Target action: basement membrane of the dermo-epidermal junction. Stimulates the synthesis of laminin-5 (laminin-332) — the main anchoring protein of hemidesmosomes — and collagen XVII, which retains basal keratinocytes. Weakening of the basement membrane is a mechanism of sagging and loss of tone with aging.
Lifting serums and products against skin sagging. Especially effective for the skin of the face and neck. Combines with hexapeptide-11, palmitoyl tripeptide-5 for synergy at the level of different matrix structures.

Main Actions
Both affect the basement membrane, but somewhat differently. Hexapeptide-11 (Filmexel) — stimulates laminin-5 and accelerates cell renewal through yeast peptide. Acetyl tetrapeptide-9 — more specific to laminin-332 and collagen XVII through synthetic acetylated peptide. The combination of both in one formula — synergistic effect on the basement membrane.
