Volcanic Ash Thermal Mask

I just wanted to make a quick note about the new Volcanic Ash Thermal Mask from MAC:

For those of you who have never used thermal masks or thermal face washes before, Biore's skincare line has both a mask and cleanser option that also "heats up", albeit lacking the Volcanic Ash ingredient. I wanted to remind you that although the thermal or heating part of the products are 'neat', it does nothing for your skin and is a gimmick. The heating is a result of a chemical reaction of a mineral in the product that is activated by water and therefore is a superficial sensation that in reality does nothing for your skin.
Of course, I'm not bashing the product because I have been using it this whole week and I do enjoy it (full review to come)... but I just wanted to put it out there and remind you all that it's not the HEAT that is making your skin feeling smooth but that it is the other ingredients that provide the benefits of this mask.
