I used bio oil as I swear by it, used it on my tummy through both my pregnancies and got no stretch marks at all ! So after my op I have been using bio oil and almost a year down the line they are so faint . The only downside to this is that it’s really oily and your bra can sometimes rub where it is and make it itch so I used it before bed and had no problems! The dermatix scar strips are good too x
