On the packet it said it might tingle and it definitely did! But I quite enjoy that in a face mask, so it was all good.
My skin was a little red when I took it off; however, it said it would detox my skin and when I removed it so many blackheads and impurities had come up on my nose and chin, which I found very impressive after only 15 minutes. I did an extraction afterwards and it was way more effective than it usually is, so I know this really worked!
