I used the cheap bio oil (wilkos/poundland both do one) from day 1 of my 1st pregnancy & not 1 stretch mark - a miracle really as I was massive xx

I have always used it right from the start of my pregnancy . Works best when you just got out of the bath or shower and your still wet

Can I use it before my 2nd trimester though? xx

I have only used baby oil on all 3 my pregnancy's

its good for stretch marks x
