I am on my second pot of this product. Mask of Magnaminty is a bit costly (nearly 20 bucks per pot) but it smells so delicious, like a vanilla-ry, minty scent.
I notice when I wash it off my face is noticeably smoother, but it doesn't really reduce the redness of existing pimples or breakouts. However, the next day, I do notice that blackheads or whiteheads are "pulled" more to the surface, which I think is due to the bentonite gel. You can also use it for back acne, but I haven't tried it for my back, because I don't suffer from back breakouts.
I probably will not repurchase to find more effective products, but it may work for others.
I occasionally grab the small tub of this mask as I really enjoy it fresh out of a cold fridge on a warm summer day but it can be a little too powerful if used often hence why I only get a small tub.
It really manages to pull all the gunk out and if you have a spot it will be gone by the morning there is no worry there, but it can suck a little too much of the natural oil out and I find that in some areas I end up with a little dry patch that is recovered by apply a nice oil before bed but it is a caution.
