This is one of the better clay masks I have used.
The packaging feels very luxurious and while the pottle may seem small, a little bit goes a long way. It also comes with a little spoon to help apply the mask to your face which I like - definitely comes in handy if I have long nails.
I think this mask is a little bit more hydrating that your average clay mask. After I've used it my skin doesn't feel all tight like it sometimes can with other clay masks. I also think that this mask has a better consistency than some other clay masks I have tried.
The product itself does have a bit of a strong smell but I don't find it unpleasant. Maybe try to smell before you purchase if possible.
Occasionally, I do have a very mild reaction to this product. My skin will go red and feel slightly hot. This reaction doesn't hurt and is so mild that it hasn't stopped me from using this product again. However this could be something to keep in mind if you have very sensitive skin.
