I have tried many masks all to help ease my acne prone and extremely oily T zone. A little bit of this goes an extremely long way and will last forever. Initially, the feeling of the mask is nice and smooth and feels luxurious going onto the skin. I leave it on for a total 20-25 minutes and can see all of the gunk that it takes out of my pores. This leaves me a little bit read, but I believe its from the pulsating from the circulation of blood. I did notice a small purging the day afterwards, but nothing big just a feel small breakouts on my cheeks where I had most of my clogged pores. I noticed an instant shrinkage of my pores.
