Radio-frequency cosmetic instrument

The embodiment of the invention provides a radio-frequency cosmetic instrument comprising a heart rate collecting circuit, a processor, a control circuit, a driving circuit, a radio frequency energy generating circuit, and an output electrode. The above-mentioned units are connected successively and electrically. The heart rate collection circuit connected with the output electrode electrically is used for collecting a heart rate of a user and sending the heart rate to the processor; the processor is used for analyzing the heart rate of the user to obtain a first analysis result and sending the result to the control circuit; the control circuit is used for sending a first control signal to the driving circuit based on the first analysis result, so that the radio-frequency energy emitted by the radio frequency energy generating circuit can be controlled by the driving circuit; and the radio frequency energy generating circuit is used for sending the radio-frequency energy to the output electrode.
