I also use the Blue Tansy mask, which I really like, and decided to try this one. The smell is light and pleasant, and when the mask dries it's almost translucent on the skin. It rinses easily and isn't messy to use. The first time I used it I wasn't entirely sold, but when I touched my skin the next morning it felt softer and looked brighter, almost like a light glow.
I used it three days in a row and now use it 2x/week (and the Blue Tansy one 2x/week). I'm thinking of trying the Prism mask next. Herbivore makes amazing masks! I'm sold.
