Most women pay special attention to what goes into their bodies when they find out they're pregnant. But do you know the best and worst products to put on your body when you're expecting? Some skincare products will work wonders for pregnancy ailments such as breakouts and stretch marks, but there are some that are downright dangerous for a growing fetus. And if you plan to breastfeed, then you should follow the same guidelines until you stop nursing. First, avoid retinoids - it's present in many antiaging moisturizers, and in pill form, it's particularly dangerous for fetuses. Avoid medications such as Accutane and Retin-A, and consult with your doctor about any other medications you use. Alpha hydroxy acids, or AHAs, are OK to use if your doctor says it's OK.
