I didn't expect these masks to do much to control my acne, but they actually work! I've used them a couple of times when my skin has started to break out and the next day my face has been a lot better! Even when I had one very visible pimple, it had almost disappeared the next day after using the mask. The mask has a very fresh smell and feels cool. It tingles a bit when it's on, but doesn't irritate my skin. The only annoying thing is that the shape of the mask doesn't fit my face well at all. The eye holes are tiny and very close to each other. Also, the mask is too long for my face, but somehow not quite wide enough. Which is weird since I have a small, long and thin face. However, despite the odd shape, the formula of this mask is great. I will probably repurchase it since it really helps my skin.
