If the stretch makrs are white there is not a lot you can do about them as they are basically the same as scars. If they are red you can by creams etc to fade them and eventually get rid of them. I know decleor did one, used to be called 'gel prolagene' but think they have changed the name to perfect contour or the likes. I know Clarins do an oil and a cream and also a bath and shower gel called tonic which helps to prevent them, i know a few pregnant ladies in the past tried them and they never recieved any stretch marks although i know some people just dont get them during pregnancy. If you do have white stretch marks the only thing i could suggest is maybe laser surgery or something but i dont know how this works for scarring really. Hope this helps anyway LL
