I got stretchmarks at about 19wks, I was using bio-oil before they showed up, then I switched to Jurlique Hops Lotion (which is really REALLY stinky) and then I put macadamia oil over that. Within 2 weeks there is NO sign of them at all!! I would recommend it to anyone - if you can stand the smell! The hops lotion is about $30 and you can use any sort of unfragranced carrier oil the one I got was about $9.
