Ingredients - why have 1 pure oil when you can have a squillion ingredients that will just clog your skin and break you out?!
My main issue with bio oil (other than the fact its petro-chem central), is that there are so many ingredients, and none particularly nice. I'd rather use a nice rosehip or organic oil blend.
Results - I used this to try and prevent stretchmarks with my first child - it did not work. And yet, after using a rosehip oil with my second I was left with LESS stretchmarks.
So in short. It doesnt work and its chock full of ick.
I haven't noticed much difference in my skin (i only use it on my face) aside from less dryness especially in my nose which become flaky in dry weather aha. I was hoping i would look like a baby after using this but thats quite unrealistic. it has a smell to it i haven't smelt before but its not too bad. Because it's an oil i do look oily when i wear it so i dont use it during the day which might be why i haven't noticed much of a difference. My friend who uses this product, however, says she noticed her skin was becoming more even in tone but she uses this more frequently than I have. I'd definitely recommend if you have a dry nose to try this.
