I used Bio Oil for a few weeks in an attempt to reduce the appearance of minor stretch marks. The bottle is pretty standard, however a screw top lid is not ideal when you are left with oily hands. I also found it difficult to control how much product was dispensed, and almost always ended up with too much. The oil has almost no scent, isn't luxurious to use and feels like it is sitting on top of the skin. It leaves a very oily residue, which would be okay if it was only being applied to a small scar.
I used Bio Oil for a few weeks, and noticed no difference in my stretch marks, however I wouldn't expect to for this period of time. I replaced my standard body butter with Bio Oil for that area of my skin, and I found that it become dehydrated. Not flaky or dry, but certainly dull and dehydrated. I stopped using Bio Oil after reading the ingredients and deciding that it was something that I no longer wanted to apply to my body.
Used it through my pregnancy and helped my skin stay soft but didn't help with stretch marks! Lol also used as a face moistiser as i had uneven skin tone but didn't help there either, plus its quite pricey!
