The efficacy hinges almost entirely on a high concentration of the Matrixyl 3000 complex (palmitoyl tripeptide-1 + palmitoyl tetrapeptide-7) and a simple hydrating gel base; there are no retinoids, strong antioxidants, or additional clinically proven anti-ageing actives to boost results, but as a dedicated peptide booster layered under other treatments it is well-positioned to deliver incremental wrinkle-smoothing benefits over months of consistent use.

EXTERNAL CITATIONS
Palmitoyl Tripeptide-1: Matrixyl 3000 is a complex of palmitoyl tripeptide-1 and palmitoyl tetrapeptide-7, shown to improve signs of aging such as fine lines and wrinkles by supporting key structural components in the skin.
Palmitoyl Tetrapeptide-7: The palmitoyl tetrapeptide-7 component of Matrixyl 3000 helps reduce visible signs of aging through biomimetic signaling that can stimulate extracellular matrix renewal.
Glycerin: Glycerin is a well-studied humectant that improves skin hydration and barrier function, widely supported in clinical and cosmetic dermatology literature.
