I personally would just let nature do it works - let it work itself out naturally.
Thing I have found with Bio Oil is, it has worked fabulous for my scars and is still workin now after using it for approx 5weeks however, it is quite oily therefore I personally wouldnt advise applying it to your face (although it says you can) as im sure a break out of spots may occur. I could be wrong but thats my personal opinion.
