Hey Vicky
I went to my chemist and asked her if honestly she thought that those stretch marks creams really works.
She says only moisturizing and massaging your skin can help (although it might not work...) and that it was pointless to buy any expansive cream. Especially that towards the end of your pregnancy, you will have to use a lot of cream, so it would cost you a fortune!!
I already have stretch marks from teenage years, so I started very early in pregnancy to use a cream for very dry skin.
I bought one from boots : Mediterranean apricot olive honey body butter for very dry skin. As well, it is organic which I think was better for pregnant bellies. It is not so cheap but a lot cheaper that any stretch marks creams( I think i paid £7 for it)
I did get the chance to have a big belly

, but i did not get anymore stretch marks on my boobs...
hope it helps
