after having three babies and three c sections, my poor stomach is a mess of stretch marks and scars *sigh*
but i have been using bio oil for years now and it has made a difference in how they look and feel. plus it smells nice

yes, it's pricey but a small amount goes a long way and it can be found fairly cheaply on Ebay.
i use a capful in my bath water to moisturise my whole body and then rub in a small amount when i get out.
it's not a miracle solution to stretchmarks. i don't believe there is one.
don't let your stretchmarks get you down. no-one is perfect but everyone is beautiful in some way.
