I have used this product before as my mother owns it, and I've only ever used it cold (didn't even know it can be used hot, not sure if that would feel good on your face anyway). After letting it sit in the fridge I placed it on my face to try to get rid of my almost permanent dark circles and bags under my eyes. It did work quite well, but putting anything cold in that area should make the bags go down; this just made it easier than trying to rub ice cubes under my eyes. I have a tiny head, so this doesn't sit well on my face, and thus, I can only use it while laying down. My mother however, uses this for her headaches and claims that it does take away quite a bit of the tension.

J'ai à la maison ce masque thérapeutique depuis quelques années. J'aime l'utiliser quand je sens une fatigue oculaire et cela me relaxe. De plus, selon nos préférences, on peut soit le réchauffer ou le mettre au congélateur ou au frigo pour le refroidir, je trouve cela pratique avec 2 façons de faire.
