I dont know what all the woman are using to try and prevent stretch marks but I started using coconut oil and its fantastic and not even expensive. Its a good antibacterial and antifungal and apparently also eases diaper rash. It smells good and i read that Coconut oil is also able to penetrate your skin on a deeper level than your average product because of its low molecular weight and the way it bonds with proteins. If you are struggling to find a good but not expesive product i strongly recommend coconut oil 👏
