Baby oil. Put on wet skin after shower or bath.
I used Palmers cocoa butter for both of my preg. Every day on my tummy, boobs + waist. Not 1 stretch mark. Try not to just pig out 2, Ur not actually eating for 2, ur only eating for u and someone that has the stomach the size of a cat. remember why we get them. gaining weight too fast for our skin to adapt. Try not to do what my sister did either. She had 4 wks to go + was sick of not being able to c p past her belly so grabbed her tummy + pulled up to c past it. In the process has seen her skin ladder like stockings from her pubic area to her naval. I've heard bio oil is good 2 but lots more expensive.
There is no such cream I tried each and everything nothing worked for me , but you can try chocobutter cream for strech marks
I use a TON of stuff, but Bio Oil and Palmer's Tummy Butter are really good
