Made from two different types of synthetic peptides, palmitoyl tripeptide-1 and palmitoyl tetrapeptide-7, the trademarked ingredient Matrixyl 3000 works to erase signs of aging. As a peptide, the ingredient is derived from strings of amino acids. Lab-created peptides mimic the ones in our body that create collagen, improve the skin barrier, and serve other functions throughout the body.

With Matrixyl 3000, the two peptides it's composed of are messenger peptides that signal to the cells to strengthen the skin barrier and increase collagen production and elasticity. The fast-acting ingredient smooths over signs of aging and texture, illuminates the skin, boosts hydration, and soothes inflammation. Its gentle nature makes it a great alternative for retinol or acids if you happen to have sensitive skin.

While it's safe for pretty much any skin type, Matrixyl 3000 shouldn't be used in the same routine as other strong active ingredients, like retinoids and chemical exfoliants. It's also best to avoid using vitamin C and Matrixyl 3000 at the same time, as the former can decrease the potency of the latter.
