A multi-purpose self-temperature control film, from outside to inside at least comprising: a functional material carrier layer (1) and an insulating layer (2) closest to the skin (4)； the functional material carrier layer (1) is a sealing cavity structure formed of a flexible water-impermeable material, said sealing cavity being at least loaded with cooling or heating chemical raw material (11)； the insulating layer (2) is formed of a water-impermeable material having insulating properties. The film can be manufactured into a face mask or an eye mask for use on facial skin. If the film is loaded with heating chemical raw material, the insulating layer (2) allows the heat emitted from the functional material carrier layer to be uniformly and steadily transferred to the skin (4), such that the heat transferred to the skin (4) does not dissipate quickly, the risk of low-temperature burns caused by the initial temperature being too high is prevented, and the skin (4) is effectively kept at a suitable and even temperature. If the film is loaded with cooling chemical raw material, the insulating layer prevents the functional material carrier layer (1) from instantaneously absorbing the heat of the skin, prevents localised frostbite, and allows uniform heat exchange between the functional material carrier layer (1) and the skin (4)； cooling time is significantly prolonged.La présente invention concerne un film à auto-régulation de la température à usages multiples, comprenant au moins de l'extérieur vers l'intérieur : une couche (1) de support de matière fonctionnelle et une couche isolante (2) au plus près de la peau (4) ； la couche (1) de support de matière fonctionnelle est une structure à cavité d'étanchéité formée d'une matière flexible imperméable à l'eau, ladite cavité d'étanchéité étant au moins chargée d'une matière première chimique (11) chauffante ou refroidissante ； la couche isolante (2) est formée d'une matière imperméable à l'eau ayant des propriétés isolant
