Organic stretch mark oil/cream?

Adina • I`m 24 with a 2 year old boy and another on the way. Married for 3 yrs.
Does anyone have any recommendations for stretch mark creams or oils? Preferably something organic but all suggestions are welcome!
 I just try & keep it as organic as possible since our body absorbs 60% of what we put onto our skin. I don't have any yet but my stomach is beginning to itch & I've read that that's a start. 
I was thinking about the tummy rub stretch mark oil by mama mio bc it had good reviews or the organic one by SheaMoisture(I love their products.)
