I got this from my beloved cousin in Hong Kong, who had travels to Taiwan recently. I have tried the My Beauty Diary mask which are amazing and my skin alway feels amazing afterwards. The difference between the 2 is that this one is much thinner and of you leave it on long enough it actually almost dries up completely. It also leaves my skin soft and hydrated. Because I can't read most of the Chinese words I am uncertain what this one does specifically but I do like it. I actually prefer the thinner mask so at least I know when I've had it long enough (although you can never it on long enough because it's so cool and refreshing for the face). I find that the extra serum absorbs really well after you take the mask off which differs from the My Beauty Diary. I like them both and in terms of performance, I am uncertain just because I have not used it enough. Another important note, it did not break me out and it has a nice fresh scent for those that might be sensitive.
A for awesome !!
