Bio Oil’s been around for ages, and is still just as popular as it ever was. I make my own sugar scrubs and always put some bio oil in along with the carrier oil. I find it gives my scrubs a nice texture and always leaves my skin feeling soft and silky.
Not a great believer in it as a scar/stretchmark remover though. Plastic surgeon told me that it kind of flattens the scar and spreads it out so that it doesn’t look quite so visible. So not appropriate if you have a major scar as it will actually look worse.
