I lost a great amount of weight after pregancy and i have a lot of dark stretchmarks. Any product you can suggest to help it fade? Or will it ever fade?

Stretchmarks are scars etched deeply in our skin so if ever it fades, I am sure it will take a lot of time and effort. Been using Bio Oil for almost 3 months although there are times that I don't use it religiously. I think it made my tiger stripes appear better than before.
