unable to keep it fresh after open the packexpensivenothing spectacular [SEP] not so unique i have used similar product selling elsewhere provide a similar result it is gentle i have sensitive skin and i have no issue with this face mask feel and looking good does not last after application my skin feels soft and even pores seem to be smaller however this good feeling looks last just a few hours once open the container there is no way to keep the lid down to keep it fresh for the next application packaging is awful the amount of the mask in the little pouch tub may last application maybe a week supply for the face regiment however after you peel off the container there is no way to keep it fresh even tight zipped lock bag would have been better it is an expensive product for what you are getting it may seem cheap since it is under but if i want to keep up with this mask application as suggested a week what came in this package would just last me about a week it would cost me monthi love korean cosmetic in general but i will not be buying this again i cannot say for sure my skin will change for the better if i use this product week as suggested for long period of time but i am not the buyer of this product for a long haul
