The beauty instrument body 1 is provided with a control module 10 for controlling the operation state of the electrode pairs and the array of colored lights 20 according to the function mode, and the electrodes and the array of colored lights 20 are electrically connected to the control module 10.

The control module is specifically used for controlling the electrifying state and the electrifying duration of each electrode pair according to a function mode instruction sent by a user, simultaneously controlling the colored lamp array to output light with corresponding colors, timing the current function mode when the function mode is switched, and closing the electrode pairs and the colored lamp array when the set time of the current function mode is reached or the total working duration reaches the set time.

For example, two adjacent electrodes form an electrode pair, and the control module 10 sequentially controls the electrode pairs to be energized according to the first function command, and simultaneously controls the color lamp array 20 to emit the first color light. The electrode pair may be an electrode pair formed by two adjacent electrodes, or an electrode pair formed by one adjacent electrode and another adjacent electrode, or the electrodes may be spaced to have the same polarity, and the other electrodes have the other polarities. The first color light may be a red-yellow light, which helps to promote collagen production. Specifically, the electrodes participating in the work may be odd-numbered peripheral electrodes as anodes, even-numbered peripheral electrodes as cathodes, and the central electrode may have any polarity or may not participate in the work.

The invention sets a plurality of electrodes at one end of the beauty instrument body 1, sets the colored lamp array 20 under the electrodes, and the control module 10 controls the electrode pairs to be electrified in sequence according to the first function instruction, so that the electrode pairs are electrified in turn to stimulate the skin of a user, and controls the colored lamp array 20 to emit the first colored light, so that the beauty instrument has the functions of electrical stimulation massage and photon irradiation, the functions are rich, the skin is prevented from generating adaptability, and the purchase cost of the user is reduced.
