My wife had developed stretch marks on her abdomen during her first pregnancy. I saw the ad of bio oil and decided to give it a try.but to our utter disappointment even after using it for 3 months there were no changes in her stretch marks.but at the same time I was applying it for my acne scars, although the scars didnt completely vanish but they appeared to get lightened.
No according to me it is good for acne scars but not for stretch marks or it may also be that it suits some skin well. Overall its better not to give it a try for stretch marks.
