This product didn't prevent me from getting horrible stretch marks, no i didn't expect a miracle but when i fell pregnant i started using bio oil in my first trimester and used it religiously through out hoping that it would at least mean my stretch marks wouldn't be to bad. I brought so many bottles of it and it was all a waste of money in my opinion. In my third trimester i got the worst stretch marks, super fat and purple, i then tried applying it 3 times a day instead of 2 and had it in my baths. But no it was a big fail i still have horrible stretch marks, they are no longer purple but that is no thanks to bio oil because they faded after i stopped using it. I still have 2 bottles left and i don't know if i want to try use them as just a moisturizer or if there is any point.
