I just wanted to share a tip that I've discovered regarding getting the most of the Acne.org 16oz. bottles after the pump no longer dispenses the product. You'll need the type of caps that come on the travel size bottles, the ones that you push down to open. Those fit perfectly on the 16oz. bottles so after the pump no longer works, just put one on, turn the bottle upside down, and you can easily use the entire 16oz. bottle until it is completely empty.
