I got a few red ones when I was pregnant with my DS, despite using the Palmers, but after a while they ended up fading.
This time I have been rubbing my belly with plain old sorbolene cream the the marks have stayed pale and are not red yet- maybe it's because I have been "pre-stretched" by DS?
I have heard of a cream called Mederma that is supposed to fade stretch marks and scars, but I am not sure that it is safe to use during pregnancy, so please don't use it without checking with your doctor first.
