I'm on the Regimen at acne.org so I wash my face, wait 15 minute, apply Benzoyl Peroxide, wait 15 minutes and apply my moisturizer. It works sooo good, at least for me, I haven't had zits for a while now. It's kinda tedious, seeing as it takes 30 minutes to wash my face, and then I still have to put make up on. But I'm not sure if Benzoyl Peroxide is safe if you are pregnant.
