Is Matrixyl injected or applied to the skin?

Matrixyl is a topical cosmetic peptide. The palmitoyl tail is added specifically to help the pentapeptide penetrate the stratum corneum when applied to the skin surface.

How does Matrixyl pair with other skin peptides?

It is frequently combined with neuromodulating peptides like Argireline or SNAP-8 and with copper peptides like GHK-Cu, addressing collagen synthesis and expression-line relaxation through complementary pathways.

Matrixyl

Also known as: Matrixyl, Palmitoyl Pentapeptide-4, Palmitoyl Pentapeptide-3

Matrixyl is a palmitoylated pentapeptide (Pal-KTTKS) used topically to stimulate collagen and extracellular matrix synthesis. It is a widely studied cosmetic anti-wrinkle peptide.

Mechanism of Action

Matrixyl couples the matrikine pentapeptide KTTKS, a fragment of type I collagen, to a palmitic acid chain that improves skin penetration. The KTTKS sequence acts as a feedback signal that stimulates dermal fibroblasts to upregulate synthesis of collagen I, collagen IV, fibronectin, and glycosaminoglycans, mimicking the matrix-remodeling signals seen during wound repair. By promoting extracellular matrix renewal it improves dermal density and reduces fine-line appearance.
