I was always so afraid of what my stomach would look like should I fall pregnant. I have horrible stretch marks on my lower back and upper thighs. I started using bio-oil at the very beginning of my first pregnancy. Two kids later and not a single stretch mark on my tummy. It truly is amazing. After applying the product you have to wait a bit as it can leave oil marks on your clothes. It has a pleasant smell. I have recommended it to both friends and family.
