works but not good for sensitive or dry skin [SEP] this mask i didn t like as much as the other three charcoal ones i ve tried it does clean pores very well and help draw out impurities and grossness i had a few emerging tiny blemishes and after using this they came out healed and disappeared within two days however it s extremely drying even on areas that weren t dry to begin with also this is the most painful one to peel off in my personal mask history messy too but all black charcoal masks are follow immediately with a good face moisturizer or oildon t know what the use by timeline is on these things but this one doesn t hold out so long i ve been using it about once a week for four months in between cleansing and washing then moisturizing but recently i found the formula lumpy and congealed making it very hard to applyin the description a money back guarantee is mentioned that s definitely a plus because while the cons may outweigh the pros i think it s worth a try it may be better for oilier faces since mine went bad though i ll be tossing it
