Stretch Mark Removal??

I've always had issues with stretch marks because I've gained and lost weight alot in my adult years. I usually get rid of them pretty easily with bio oil but for some reason it's not working as well this time. I mean I'm still not showing much so I'm worried once I'm bigger the marks will get out of hand so I want to start now and have something that will work all the way through. Any recommendations?? Please and thank you.
