They may fade with time but never go away. My son says my stomach is bumpy and it's True it's like speed bumps to the touch.

Theres nothing but keeping hydrated & moisturize.. im 31 weeks & getting them even though ive been moisturizing every day. Youll get them regardless.
There's nothing you can do to get rid of them..
