This is a smooth, self-heating mask you pack on and then wash off. It doesn't come with any kind of applicator so you have to use your hands. The mask starts off as a dark, semi-clear goop that turns a pale off-white as you rub it onto your face. The friction from your fingers will activate it's heating process - it doesn't get too hot but there is a nice, tingly warmth. Your face feels pretty tight afterwards and the skin feels soft and smooth as well.
