The self heating exothermic warming film comprises at least a three-layer structure comprising an outer layer (1) made of a breathable material in each of the outside and the inside, a exothermic composition (21) (2) in which the upper cover surface to be contacted is made of a breathable material, and a heat insulating layer (3) composed of a material having waterproof and heat insulating performance. The self heat generating thermal insulating film is simple in structure, is free from the restriction of environmental resources, and is not required to be supplied with energy from an external energy supply source, and is safe, stable, uniform in heat generation and can effectively extend the heat generating time, The peak temperature can be lowered. The self-heating heat-insulating film can be made of a 3D face mask, a face mask or an eye mask, and is used for the skin of the face area to improve blood circulation and enlarge the skin pores to discharge sweat and sebum. When used in conjunction with conventional nutritional face masks or skin care products, it is possible to increase skin absorption of active ingredients of conventional face masks and skin care products, reduce the amount of skin care products used, and increase skin care benefits Safe, hygienic, and inexpensive to use. |
