I had HORRIBLE acne that started in my first trimester. You are not supposed to use salicylic acid or most other acne meds. What I found was a fairly cheap face soap that is actually fragrence free, soap free, and hypoallergenic at walmart, and it doesn;t have any harsh chemicals in it that can hurt the baby. Anyway, I love it, and it worked absolute wonders on my face, I also use their moisturizer which has SPF. Anyway, I buy it at Walmart and the brand name is "Purpose"
I've been told the only acne medication you can use is benzoyle peroxide...it is the active ingredient in clearasil vanishing cream and a clean and clear face wash...A lot of products use salycilic acid and I was told that is not safe to use during pregnancy.
