I have sensitive oily skin which is prone to the odd breakout around my menstrual cycle. I was highly advised to buy the mask by the Space NK sales assistant as she said it would help dry up any break outs. Apart from the horrible smell and consistency this stuff really messed up my skin. I had a terrible allergic reaction and my skin the next day was 10 time worse in terms of break outs. If you have sensitive, breakout prone skin do not use this. It may be good if you skin is not sensitive. It is insanely expensive as well. Not a good product at all for me.
