I had severe acne and it occasionally still flares up. I was so self conscious going to xmas parties that I had my fiancé put concealer and makeup on my back acne. My dr said it was hormones. I kept telling myself that I could be a lot worse (I only had a little nausea my first 9 weeks and no vomiting) and tgat it will pass (someday lol). My dr recommended using a gentle cleanser such as cetaphil and to stay away from high fragrant soaps, etc. I also spot treated the acne with benzoyl peroxide which seemed to have helped. Good luck!
The reason is bc you're pregnant. And bc all your hormones have changed. I get it too it totally *****
