M.M.
I'm sorry you're dealing with this.
My face was HIDEOUS with my first. As was my chest, back and arms. I was covered in acne, and my face was covered with cystic acne.
I was normally someone that had totally clear skin.
Honestly, not much worked for me. I eventually developed a routine of holding a hot washcloth on my face at night (draws the toxins to the surface), and then benzoyl peroxide. (No, it didn't not hurt either of my kids.)
I did discover a product called Buffering Lotion from Mario Badescu.
www.mariobadescu.com. It was the only thing that helped my cystic acne heal faster. Not go away...but heal faster.
I'd put that only nightly.
Good luck.
On the plus side, I will say that after I had the baby, everything went back to normal. But that's a long 9 months to endure. :(
