I have been using Bio Oil from about 3 months, now just past 7 months. Clearly the packaging says that it can be used during pregnancy and I know that many people do (a friend included). It is particularly important for me as I have a significant scar across my belly which was from a serious operation I had when I was a baby. To date, it looks like no scars are developing as the skin stretches around that major scar. Of course this is a good thing but then (via an Amazon review) I've heard it's contains vitamin A and therefore should not be used. I have gone onto their website and it confirms it's safe to use during pregnancy, www.bio-oil.com/en-us/product/formulation. In any case, I thought it was only Vitamin A from liver etc that was the issue? Thoughts/experiences appreciated! Many thanks
