No7 Purifying Sauna Mask Review

No7 is not a brand I can say I know much about, so when I was given a "£5 off No7" voucher recently, I wasn't sure what to use it on (being a bargain lover, the idea of not spending the voucher didn't occur to me, even though there wasn't anything I actually needed!). Having since read quite a few reviews, I would now know to use it on the Quick Thinking 4 in One Wipes, which seem to really impress people. As I am a lover of face masks, and because I had a bit of a spot erruption on my chin at the time, I gravitated to the section which held deep cleaning products. Eventually I settled on the Purifying Sauna Mask, (I am a total sucker for names, and the idea of a sauna mask hooked me straight away!), which was £6 after the voucher discount.

As the mask was self heating, I imagined it would be lovely for opening up my pores, and giving those pesky spots a bit of a seeing to. I have had this product for about a month, and tried it about 7 or so times, so I feel I've given it enough chance to impress me. 
 
Firstly, I'll start with the pros's..

1. Smells nice (Possibly due to the Rosehip oil it contains)
2. It really does feel lovely the way it heats on your skin
3. Would probably work very well on oily skins

Now for the con's (slightly longer list unfortunately)..

1. Quite pricey...even with the voucher, £6 for 75ml seems a lot, and there is no way I would pay the original £11 for it!
2. The heating sensation only lasts for a few seconds
3. The pumice grains in this are quite rough, and it does feel rather like you are sandpapering your face
4. Leaves a chalky residue on the face no matter how you try and take it off 
5. Really dry's the skin, even after the first use my face felt tighter and had dry, flaky patches
6. Doesn't actually help with spots (although, it didn't break me out..)

So, overall, I wasn't impressed, but I can see how this could work for oily skin types. Definitely not worth £11!
