Zero Sebum is amazing! It has the consistency of baby powder and it's so easy to apply. At first, I thought that I would go through this within a month because I have combination skin (more on the oily side), so I planned to use this multiple times in a day. But after weeks of using it, it still looks relatively unused because a little goes a LONG way! The only complaint I have is that you either have to lift up the plastic compartment to get the powder or shake it a little (so that the powder goes through the holes). The problem with that is that the powder will spread everywhere.
