I was very intrigued with the idea of a self-warming facial mask, I thought it had to feel and work just great, so I bought it, despite the price tag of $14 for a 3.4 fl.oz. tube. The Body Shop Warming Mineral Mask contains kaolin clay and wild-harvested seaweed; it is said to deep cleanse your skin and clogged pores as it "magically warms itself" on your face.
Impatient as I was to try it, I took time to read the directions first. They were brief and clear: the mask is to be applied onto clean and dampened face, left for 5 minutes and then rinsed off. The first disappointment came as I began to apply the mask: it was thin and runny, and the fact that I had dampened my face, according to the directions, did not help: it made it run even more. Somehow, I managed to put the mask on, after all. As I relaxed to enjoy it, I felt the promised warming sensation, and it was wonderful... while it lasted. And it lasted for only about a minute.
When the warming effect had stopped, I decided to wait until the mask hardens and then remove it. Here came the second disappointment: it would not harden. At all. Not after the required 5 minutes, and not after 10. I'd gotten tired of sitting there with that runny stuff on my face, so I washed it off.
My skin looked clean, not greasy and not dry. That was good. However, I did not see any special deep-cleansing effect; some regular scrubs work better that this. My final verdict is that a one minute of pleasant warmth is not worth $14.
