im prone to them i got them on my bum and a few on my boobs whilst pregnant, i was really annoyed actually i used palmers and bio oil from the day i found out i was pregnant on my stomach and not 1 stretch mark there why didnt anyone tell me about the ass it now looks like spagetti junction lol.
anyway i had 410s from a 34aa and no stretch marks and the few i had on my boobs i can no longer see, i think if you’ve had kids and they’ve already stretched you should be ok, use the creams there great. x
