<p>The hot and cold skin massaging device combining ions and middle frequencies of the present invention has an ion-outputting function, a middle frequency output function and a heat output function, and uses a frequency resulting from the synthesis of a direct current wave and a pulse wave in order to increase the percentage absorption of cations and anions upon ion output, such that it is possible to provide a hot and cold skin massaging device combining ions and middle frequencies whereby skin absorption can be increased.</p> |
