The wikipedia article about stretch marks says there is no scientifically-supported treatment for stretch marks, aside from laser removal. They will fade with time. I have some that are nearly gone, a couple years later. I used Bio-Oil for a little while, but hated dealing with that super-greasy stuff, never came off my hands, and didn’t seem to be doing much. (Then again, the bottle says to use it three times a day. Seriously?) I just moisturized after each shower with body lotion, not sure if that made a difference. Cocoa butter is also rumored to help, but no guarantees.
