I used up the whole box and it was amazing. In particular, when I used this enzyme cleansing powder after soaking in the bath to thoroughly open my pores, it completely removed the blackheads around my nose. I felt that the green one was much more effective than the pink one. Another great thing about it is that it's individually wrapped, making it easy to use! Rather than using it every day, I used it whenever I noticed my pores becoming more noticeable, so it took quite a while to use up all 30 bottles, which was a pleasant surprise.
