When I was pregnant with my daughters, I had acne on my face and back during the first trimester. Towards the last semester, I had very, very dry and itchy skin all over my body. No amount of lotion and emollient could bring relief to my skin. A friend of mine who was also pregnant developed a bad bout of eczema and acne. Someone recommended sulfur soap to treat the acne but I dared not try it, lest the soap contained some chemicals that are harmful to the fetus. Recently, I saw a shop selling sulfur soaps. I read from the label that it contains minerals and sulfur from the Dead Sea. Not sure how effective it is on acne and eczema. I guess there is no harm trying if you are not pregnant.
