The mask is a face-shaped cloth with holes for the eyes and nostrils. It fits over my (average sized) face comfortably. The treatment is a clear liquid gel that feels cooling and refreshing on the skin. It has very good ingredients like sodium hyaluronate, niacinamide, trehalose, aloe vera and peptides. The remnants of the fluid can be left on the skin after using the mask, there is no need to wash it off.
I was sent this single mask as a sample in a recent order from Mise Beauty, so I can't testify to long term use. It did make my skin feel refreshed and hydrated after an extremely busy weekend last weekend, when it had been starting to look a bit green from tiredness and lack of regular meals. A packet of 4 costs £24, and I'd keep a pack handy for an instant skin pick-up.
