SkinMedica TNA has the patent on a 3-D culture that creates the more than 300 growth factors to signal your own skin to “think” younger and create fetal, non-scarring collagen.

SkinMedica also has the highest level of science. They have multiple published peer-reviewed articles. They do biopsies and assays to make sure that every ingredient in their products creates the response in your skin that is supposed to be creating. They don’t just add good ingredients to their products. They make sure that the ingredients they add are doing what they are supposed to be doing.
