I've used the same type of green mask before, and I liked it so much that I bought the other three to try. This yellow mask, which also contains vitamin C, requires about six tablespoons of water using the included spoon, which I mix well before applying to my face. After about 20 minutes, it peels off cleanly, removing all impurities from my skin, leaving it with a smoother, more radiant complexion. I really like it.
