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.
Best to check with the doctor. It is known that acne skin cream can affect the fetus. Maybe best to stick with more natural remedies like Medihoney.
