I purchased this on a whim and have used it 4 or 5 times. I like masks, but find this is a bit drying and stings slight. My skin isn't particularly sensitive, is well hydrated and is generally clear. I find this mask difficult to remove, and once I've used this mask, I really don't want to rub my skin to remove it. I usually don't let it dry completely before I remove it.
I think it might be useful for people who have more active acne than I have perhaps; I don't often get blocked pores or active acne so perhaps it's just not well suited to my skin. I certainly haven't noticed any changes to the appearance of my skin.
I find the smell a bit strong and artificial, but not offensive.
I'll continue to use this mask until it's gone, but I won't repurchase.
I've only tried this mask a handful of times, because I keep wanting to love it. It feels very harsh on my skin and very very very drying, which is kind of the point, but I feel like it strips my skin too much. I also found that it didn't clear my skin, but managed to make it worse. I think my skin is too sensitive for this product.
