I bought this a few days ago and am already loving the results. The only thing I don't like about it is the fact the 30 usages. I used the product without fully reading the instructions and thought the button was a stop/ resume button. I ended up going through 6 uses on one try :( Once I read the instructions it was easy to use and was only disappointed that I had wasted so many uses on accident. My skin is already smoother in just a couple days and my acne has gone down. I would highly recommend the mask to anyone!
