The invention discloses a spontaneous heating thermal insulation three-dimensional mask which comprises at least three layers of structures, namely an outer layer consisting of a breathable material, a heating layer and a thermal insulation layer, wherein the heating layer is loaded with a heating composition heating by being contacted with air, at least the upper cover contacted with the outer layer, of the heating layer is made of a breathable material, and the thermal insulation layer consists of a material with waterproof and thermal insulation performances. The spontaneous heating thermal insulation three-dimensional mask is simple in structure, is not limited by environmental resources and realizes safe, stable and uniform heating, outside energy is not needed to provide energy, the heating time can be effectively prolonged, and the heating peak temperature is reduced. When the spontaneous heating thermal insulation three-dimensional mask is applied to face skin, blood circulation can be improved, so that skin pores are enlarged, and sweat and dirty oil are discharged. When the traditional nourishing mask and a skin care product are used together, active ingredients of the traditional mask and the skin care product can be absorbed by the skin, the amount of the skin care product is reduced, a skin care effect can be improved, and the mask is safe and sanitary to use and low in cost.
