Lotion helps prevent but doesn't make them go away. They will fade with time. You can use mederma that helps scars and stretch marks fade better and faster after the baby is here. May want to check if it is safe to use if you are breast feeding.
I dont like cocoa butter. This bio oil has been clearing uo my old ones as well as new ones. I have also just been using lotion to keep the skin hydrated. And I heard drinking lots of water helps but I dont know about that one
