I tried to use the Palmer's brand of Cocoa butter and Vitamin E and got a HORRIBLE rash from it...apparantly an allergic reaction. I had never heard of such since it is suppose to be an incredibly gentle product, so I guess I'm the strange one. Anyways, I stopped using it early in my pregnancy and was too scared to try anything else. I didn't get any stretch marks. My mom didn't get any with either of her pregnancies. I really think it's all genetics....
