I would be interested to hear some thoughts as well. I've been having awful breakouts since I found out I was pregnant and nothing seems to be helping. I started using the Boots brand facewash, serum and moisturizer but none of it helped. I know people say to stay away from salacilic acid but my Dr. advised as long as it's under 2% and doesn't stay on your face for a long period of time you can use it, so I've been back to my nuetrogena stress control and have been liking it a lot.

Olive oil. I know it sounds counterproductive to put oil on a face that is breaking out but it works. Just rub it into your skin after you wash your face, only use enough so that it soaks into your skin and doesn't leave a coating of oil on your face. It really does work and your skin will be so soft.

In had acne so bad as a teenager. I tried everything - from the natural products my grandma suggested to the chemicals. What ended up working for me in the end - water. I would splash my face with cold water in the morning and clean with just cold water. Throughout the day, just if I remembered, I would splash and rinse my face with cold water (like after washing my hands, after using the restroom). Then, at night I would use a microfiber cloth and super hot water and steam my face, followed by cold water again.
Heat opens your pores and cold closes them. Keep this in mind regardless of what product, if any, you decide to use. Open your pores before washing your face and always use cold to close them again when you are done so oil and dirt don't get right back in.
I found water only worked fantastic for me - I never found a face product that did. Everyone is different, you are going to have to find what works for you.

As far as pregnancy acne goes, that is one of the few wonderful things pregnancy does for me. My face has never been clearer and brighter than it is while I am pregnant. I glow! Yea!
