Everyone must have this mask, its simply treasure ! Due to nowadays lifestyle: sleepless, stress, high sodium food...etc most of us would have swollen, puffy face. This mask signficantly reduces those issue, reveal face contour, face looks slimmer and firmer, totally different before and after. It also contains clay/kaolin that provides clarifying beneficial for oily skin. For dry skin, just avoid applying on those dry areas. Indeed, you just need to apply around face countour, may go a little higher on your puffy cheeks. Personally, I leave it around 30 mins to see result. I enjoy using it on neck, chin, face contour and sometimes whole face, it didnt irritate my sensitive combo skin, though !
