I just bought this product recently and I absolutely love it! It's a little on the stronger end. If you've used any of the other products in the tea tree oil line you'll know the distinct smell of it. Well for the mask the smell is about 3x greater. I don't mind though since I've come to really like the smell. It makes me feel very fresh. The mask is grey-ish green in color. You apply it on your face in a thin layer (which makes this mask last forever! I got a sample to begin with and it lasted me 6 uses) and to leave it for 5-10 minutes. It's not supposed to dry up like a usual face mask does, so they say not to go over 10 minutes! You're supposed to put the mask on once or twice a week. I usually put it on twice a week (I try to at least- once on Wednesday and then on Sunday). When you put the mask on, besides the huge rush of smell, you feel an instant cooling sensation. Sometimes i tend to feel a tiny bit of a burn but I figure that's most probably because like the other products in the line, it's meant for acne prone skin. The burn is minuscule compared to the burn I usually get when I apply any over the counter acne medication (ex: I use clean and clear spot treatment). After 7-8 minutes I usually wash it off and for a good hour I feel my face being very cool which feels really great and refreshing (especially in the summer time). I do notice that it reduces the size of some of my pimples, and I feel that it speeds up the reduction of blemishes when I use it hand in hand with the other products in the line. Overall I think it's an amazing product :D and definitely an affordable one considering the long time it lasts.
