I have used BIO OIl my whole pg and it hasnt stopped the stretchies unfortunately. As ther other girls said, if you are going to get them you will get them regardless of what you put on your skin. It is good to keep it moistuised as it strecthes thoguh to stop itching. Bio Oil does say it is mean to fade scars and stretchies so i will keep using it after baby arrives and let you know
