Contractubex clearly stated that it's effective for newly formed scars. I can attest to it because I can see how my scar flattened after two weeks of use. For old scars, let say around 2 years there's a special instruction written on the box on how to use the product. This treatment is laborious; you have to apply the cream 3 to 4 times a day to see the results. Visit: http://www.daynighthealthcare.co/product/contractubex-gel
