I thought this products was mostly a novelty item, but this mask tighten my pores. The mask was easy to apply and gave an overall clean feeling. However be careful not to apply too much on one area particularly near your eyes because you eyelashes will definitely be coated in clay carbonation bubbles. One caution I would say that washing off the mask is a little difficult, and very messy so I would suggest doing this in the shower where it'll be less messy.
