Matrixyl Synth’6 is a new FDA-approved patented peptide, which is clinically proven to stimulate all 6 levels of collagen synthesis. You may be familiar with older versions of this ingredient, Matrixyl and Matrixyl 3000, which worked to prevent fine lines and wrinkles. Matrixyl Synth’6 is the latest generation of this peptide, and is proven even more effective at decreasing wrinkles, improving skin texture, and promoting cellular renewal. Matrixyl Synth’6 works by stimulating all the major constituents within the dermal matrix. This enhances collagen synthesis, which in turn effectively plumps and smoothes away wrinkles from inside the skin. Matrixyl Synth’6 is contained in all KAPLAN MD Concentrate products, and in the concentration it was clinically tested for the most effective results against skin aging.
