Bio oil. Sounds quite natural - but its got so many ingredients, like seriously, there are over 25 ingredients It seems excessive when you can use something like olive or argan oil.
The base is mineral oil, which is essentially liquid paraffin. Gross!
I used this to tackle stretch marks when I was younger. I tried it again recently because you know, I was a judgey teen. My teenage self was right to hate it. It doesn't absorb, it just sort of sits on the skin. I had no results at all, other than my skin feeling greasy and oily.
If I could - I'd give it zero!
