Matrixyl
Quick Summary
Matrixyl is a cosmetic signaling peptide best known by its INCI name Palmitoyl Pentapeptide-4 (also written Pal-KTTKS). It is one of the most-cited peptides in modern leave-on anti-aging skincare and is widely used in serums and creams positioned for the appearance of fine lines and wrinkles. In cosmetic-appearance literature, Matrixyl is described as a "messenger" peptide that signals dermal fibroblasts toward producing extracellular-matrix proteins. It is not a neuromodulator, not a prescription anti-aging therapy, and not interchangeable with the related Matrixyl 3000 or Matrixyl Synthe-6 compositions.
What it is
Matrixyl is the trade name commonly used by formulators for Palmitoyl Pentapeptide-4, a five-amino-acid signaling peptide attached to a palmitic-acid (fatty) tail. The fatty tail is added to help the peptide pass through the lipid-rich outer layer of skin in a leave-on cosmetic. The peptide sequence itself is derived from a fragment of type I procollagen, which is the molecular family from which the term "matrikine" (matrix-derived signaling peptide) takes its meaning.

Mechanism
In peer-reviewed cosmetic-peptide reviews, Matrixyl is grouped with signaling (matrikine) peptides: small fragments described as cueing dermal fibroblasts toward producing extracellular-matrix proteins such as collagen I and III, fibronectin, and glycosaminoglycans. The original mechanism description is most often traced to Katayama and colleagues, who reported that a pentapeptide derived from type I procollagen could promote extracellular-matrix production in cultured fibroblast models.
