As countless user reviews will tell you, Bio Oil can be used for a multitude of remedies and treatments. Personally, I use it as a moisturiser when the going gets really, really tough... and dry. It's a little bit oily on your face (well, it is OIL after all) so you don't want to be applying it anytime before going out, and you'd want it to soak right in before going to bed so you don't mess oil on your pillows. But nothing else penetrates quite as well as Bio Oil when you need extra moisturising, especially in winter. The best part is it doesn't cause spots.
