A skin moisture testing system comprises a BLUETOOTH MCU control unit, a BLUETOOTH antenna impedance matching unit, a RC integral and diode rectifier unit, a sine signal unit, a first contact, a second contact. The present invention also provides a skin moisture testing method using the skin moisture testing system, the skin moisture testing method can test skin moisture value. The skin moisture testing method of the present invention is motivated by a pulse signal, the skin moisture testing method can effectively and accurately test skin moisture value. The skin moisture testing method also matches with a lower powered BLUETOOTH MCU to test user's skin for a long time, then the tested skin moisture value can be visually displayed on the APP of the terminal device, the testing data can be made to form a graph. |
