The SK-II Facial Treatment Mask works best when used alongside the other SK-II product line which are based on the miracle water aka Sake. I used the mask while using the rest of the SK-II facial products so I saw the combined results which are amazing. I almost did not want to put on the mask as it comes so heavily drenched in serum it almost seems gross & greasy bu it actually will leave your skin moisturized but not feeling like you have a pound of products or oil on your skin after your remove the mask and cleanup. The process is messy and not fun because of the way you must remain without much movement bc it feels as if it may slide off and it really is not fitted for my fave structure! But it is worth it bc afterwards your skin feels like it lost a pound of gunk, your skin feels and looks healthy and glowing. It really is a at home facial bc of both the high price and the grand results you get. My skin really did need a deep treatment of changes in weather and it still would be anproduct to use in both winter and summer time weather. I recommend giving yourself the treat and spending the high price tag for a single mask because the results will be worth it and last leave your skin happy for a long enough time!
