Stretch marks

In my opinion, no it doesn't really help that much. Applied bio oil religiously and still got a s*** ton of stretch marks during my first pregnancy, stomach literally looked like a watermelon with all the streaks. Found out only after the fact that: 1. It is genetic and hereditary. My mum also had loads of stretch marks and thus passed this undesirable skin trait to me, and 2. all the creams and oil do is to moisturize your stretching belly skin so that it reduces itching and *may* help to make the skin layers more supple and less likely to break apart i.e. stretchmarks.
