I use Cetaphil, as my RE recommended (I was using ProActive prior to my first pregnancy). I'm probably not supposed to, but I do scrub my face with a facecloth after I lather the soap onto my face. I'm surprised at the lack of acne.
ETA: I use a sensitive skin moisturizer from BioElements. It works great.
Ugh my face was a MESS at the beginning of this pregnancy... I wash with Purity (philosophy) at night to remove the makeup and in the morning I use a cream cleanser with my clarisonic in the shower. I just started doing this about three weeks ago, bc I hadn't been using my clarisonic much since I thought it was aggravating my skin more since it seemed so sensitive and prone to breakouts, but it's finally (knock on wood) clearing now that I'm being consistent with it.... now if I could only find something to help with the dark spots!
I had an allergy panel done a year ago so I'm limited to what I can use. That said, I've used a LOT of different things. I was a loyal Mary Kay Timewise user, tried On a Clear Day from Philosophy before I got pregnant (due to break outs). I loved it but it was pricey in my opinion. Then I switched to Neutrogena's basic facial cleaner (in a blue bottle). It cause MORE breakouts than it did any good. So I looked at my approved list and thought okay, I'm going to try Cetaphil. My brothers used to use it when they had acne and my mom loved how affordable it was. I tell you what, I LOVE it. It doesn't dry out my face and it has helped clear up some of the issues I had been having with the Neutrogena wash. My face is soft and clean...I haven't noticed any excessive oiliness either. The best $6 I've ever spent!
