I struggled with finding sheet masks that work with my oily skin, they usually make me break out or increase my oil production exponentially. I am so impressed with this mask, I really don't have words. I left it on for 20mins after cleasing and toning, and after I removed it and the serum absorbed and dried...I audibly gasped. My skin glowed without being oily, sticky or slick. My pores were visibly smaller. Even the next day my skin felt so soft, and didn't make my skin oilier than normal - it actually helped with keeping it under control. Zero breakouts! I'll be adding 20 to my cart in the future! I've found my new holy grail. Thank you!
