I never had a problem with acne until I got pregnant, but my skin has been AWFUL for the past seven and a half months. It seems to be clearing up a bit now (at 31 weeks), thankfully, but I'm still struggling with occasional breakouts. My neck has been the biggest trouble area, especially right under my jawline. I hope that the marks fade with time, because at the moment I look awful.
I tried a little of everything to get rid of the zits, and nothing seemed to help. I eventually gave up all over the counter products and started just using a hot washcloth (and nothing else) on my face, and surprisingly enough, that seemed to help. I do wear makeup sometimes, and then I'd use soap and a little eye makeup remover to take it off.
The other day I broke down and bought some Burt's Bees Tomato soap and toner, and I've been using it for the past couple of days. My face feels a lot cleaner and less oily (but not tight), and though I'm a little reluctant to say that I can tell a difference, I haven't had any NEW breakouts.
Guess that's not exactly advice, but at least you know you're not alone. I got SO sick of hearing people rave about their wonderful, glowing pregnant skin in the beginning when mine was at its worst.
