I happened to get a mini-version of this mask, but it lasted me a month given that I was using it every 3-4 days.
The mask is a clay mixed with some liquid. It smells herbal very potently. Moreover, I can feel some stinging immediately after applying.
It starts working right after it dries out. It performs better than an ordinary clay mixed with water. During the use your pores get visible and the mask draws out the excessive sebum straight away.
Do not expect any immediate results!
You won’t probably notice any significant changes in your skin after the first use.
However, you will really see the difference after a while provided you use it frequently. Your pores will get narrow and there will be less blackheads on your nose.
It’s one of the rare masks that really worked for my skin, but the price…
Well, I’m still on the fence if I should purchase the full-size. I now plan on trying some other masks that ensure similar results.
Straight to the point, this mask doesn’t change your skin texture. So when you stop using it, your skin will go back to its initial state. Therefore you will either have to use it regularly or look for an affordable dupe
