Myself and all my sisters get really bad stretch marks, to the extent that we look like we have been clawed on our hips or lower back. All my sisters have had babies and their tummies have really suffered from stretch marks. I am in my late twenties and i want to ensure that should my body change or should i become pregnant, that i don’t suffer the same. I would appreciate any advice or product i could use at this stage to prevent rather than treat. I know bio oil can be good. Any other ideas?
