I am having fifth month of second pregnancy, my first child is 4.5 year old, i got stretch marks on my stomach in first pregnancy, so Now using any oil massage with such bio oil or any ll work on Tht marks or are there any chances of increas of stretch mark this time also

Nothing can prevent stretch marks yes you can lighten them keep the area well moisturized with coconut oil after bath and some good cream in day.

Always keep skin mouster, don't leave skin to dry up compelety....Apply some alovera gel always, Coco oil works best....still you can talk with your gyna for best cream..
