In clinical studies, Bio-Stria removed the appearance of stretch marks at 100%. Bio-Stria, which is a relatively new treatment in which collagen is rebuilt by underneath the top layer of your skin, is also effective. Bio-Stria targets the cells below the surface to repair your skin from the inside out. Bio-Stria and our team use organic to stimulate the production of collagen for smoother, more beautiful skin. If you are bothered by stretch marks around your body, consider a Bio-Stria stretch marks treatment in our online store.
