Bag Balm works wonders.

Initially it was used to treat cow udders from chapping due to milking procedures. now pregnant moms use it to help keep the stomach skin elastic to minimize stretch marks and nursing moms use it for thie nipples after nursing their babies so that their nipples don't chap, crack and bleed.

Here there is an animal feed shop down the road that carries it. Some famacies and stores also now carry it. And I would not be surprised if there are some pregnancy and animal feed websites that might have it on line.
