Stretch marks

[Emma G 1650]

Has anybody used Bio Oil for preventing/reducing the appearance of stretch marks which occur during/after pregnancy? If so, how long and how frequent do you need to use it before you see any affects? Does anybody know of any alternative for reducing the appearance of stretch marks? Also, does exercise make any difference?

Exercise is meant to be ace for reducing stretch marks, although I don't think there's anything to get rid of them totally. There are alot of creams on the market, but I suppose they are all the same??? Useless!
