A self-heating insulating film comprising a structure of at least three layers, which from outside to inside are respectively: an outer layer (1) formed of breathable material; a heat-generating layer (2) loaded with a heat-generating compound (21) that generates heat on contact with air, at least an upper covering surface thereof that is in contact with the outer layer (1) being formed of breathable material; and an insulating layer (3) formed of a material having waterproof, insulating properties. The present self-heating insulating film is structurally simple, is not constrained by environmental resources, does not require energy supply from an external energy source, is safe and stable, uniformly generates heat, and can effectively prolong heating time and reduce peak heating temperature. The present self-heating insulating film can be manufactured into a three-dimensional face mask, a face mask, or an eye mask for use on facial skin to improve blood circulation, enlarge facial pores, and remove sweat and grease. When used in combination with a traditional nourishing face mask or skincare product, the absorption by the skin of the effective ingredients in said traditional face mask or skincare product is improved and skincare effects are enhanced even when the amount of skincare product used is reduced; use is safe and low-cost. |
