I am using Bio Oil since December 2015(now May 2016) and I have not seen any visible results on my face.
It was highly advertised online and thus after checking hundreds on reviews from worldwide ladies I bought in Rs 450 from Amazon. My objective was to fix uneven skin tone on my face.
Postives
It moisturises my skin really well.
It is not sticky or leave any greasy feeling on face.
Slight fragrance that may not be liked by everyone.
You can use it during day and apply sunscreen on top of it.
Negatives
It doesnt take care of any scars or marks.
I have dual tone or uneven tone around my mouth and nothing noticable has happened.
People on internet say that they also use this as hair oil - I used once as a hair serum. It was good, tamed my frizzy hair.
Like people have mentioned in their reviews, it doesnt give any deep nourished effects on knees, arms, legs or ankles.
I may not buy this again, just for moisturize produt at this price range!
The one I have I use it as a occasional night application.
