I never had acne until I got pregnant! In my first trimester
I had it everywhere, on my shoulders, my chest, my upper back, face, everywhere! It was so disgusting. That only lasted a few weeks. Then in my second trimester I only had it on my face, bad, but not as bad as everywhere on my body. Now in the third trimester with 3 weeks left I haven't had any.
Starting the second trimester I would do a mask on my face twice a week, a good scrub every day in the shower, and a moisturizer.
