I remember there being massive hype about this when it first came out but I never bothered with it as I didn't really have any stretch marks or anything that needed it. I have recently started to get a bit of cellulite/uneven skin tone at the tops of my thighs and got bio oil for this purpose.
It did an all right job but nothing spectacular. My skin felt hydrated in the short term, but not over longer periods and it didn't really change my skin tone that much. I have also heard negative comments about the ingredients and it does take a while to soak into your skin.
I think you are honestly better off saving your money and going for Cocoa Butter or something like that as i have had much better result using that.
I had high expectations but for me, this product didn't do as it claimed. I noticed no significant changes on any scarring or stretch marks. I will agree that it is good for dry skin but for that price there are other products on the market that are much cheaper and will give you the same result.
