I am currently on Day 5 of my new acne treatment wherein I basically don't wash my face.
Well, I do, but I only use water unless it's at the end of a day when I wore make-up. Then I use a little bit of face wash and a lot of water.
This was inspired by my husband and our friend who use nothing but water ("and shampoo if it ever gets on my face") and have no zits.
The crazy part is that my complexion is actually clearing up. But we'll see how it looks after a couple of weeks.
