So, after using my sephora bubble mask for ages, I decided to try the famous piggy carbonated clay mask. The piggy bubble mask is a clay mask, and according to my experience with this kind of masks, I expected it to dry my skin. To my great astonishment it did not happen!  Honestly, my skin was less hydrated and oxidized than with the Sephora bubble mask, but the Piggy mask shrank very well my pores and leaved my skin perfectly clean after only one application.In conclusion I can say that if you are looking for a mask to shring your pores by clearing them of accumulated sebud and dead skin cell gunk, this is a very good and funny choice. If you are more a fan of hydrated and oxygenated skin, choose the sephora one.
