Although only two electrode pair assemblies (ie, the first electrode pair assembly 710, the second electrode pair assembly 730) are shown in the skin treatment device 700 of the embodiment shown in FIG. 7, it should be understood that this is merely an example sexual. The skin treatment device 700 may include three or more electrode pair assemblies, and the signal isolation between the electrode pair assemblies and the controller 720 may be achieved through the signal isolator 725 .

According to an embodiment of the present invention, in addition to the isolation of the power supply system and/or the signal system of the electrode pairs of the skin treatment device, alternatively or additionally, the power supply sequence provided to the different electrode pairs during the operation of the skin treatment device can be adjusted. settings are made to ensure that there is no current loop between the different electrode pairs.

FIG. 8 shows a schematic diagram of the driving timing of the electrode pair according to the embodiment of the present invention. As shown in FIG. 8 , the output period of the first electrode pair is different from the output period of the second electrode pair, and it is ensured that their time periods do not have any overlap, which is shown as dead time in the figure. For each electrode pair output period, the duty cycle can be set according to the site of skin treatment. Since the output period of the first electrode pair is different from the output period of the second electrode pair, it is possible to ensure that the electrode pairs are electrically isolated from each other.

In the embodiment shown in FIG. 8 , the first electrode pair output period and the second electrode pair output period are assigned fixed time periods. It should be understood that this is merely exemplary, and in other embodiments, the first electrode pair output period and the second electrode pair output period are assigned variable time periods to maximize output efficiency.

Furthermore, it should be understood that, although in the illustrated embodiment, two electrode pairs have been described as an example, this is by way of example only. The above-described implementation can be similarly applied to the case including three or more electrode pairs. Furthermore, although in the illustrated embodiment, the drive current is shown in the form of pulses, it should be understood that this is merely exemplary; the drive current may take any other suitable form.

In some embodiments, when the output drive assembly of each electrode pair is not operating, the output drive assembly is electrically disconnected from its electrodes to further improve the electrical isolation performance of the skin treatment device. In some embodiments, zero current flow is ensured when the output drive assembly of each electrode pair is not operating, even if the output drive assembly is not electrically disconnected from its electrodes. In this way, the electrical isolation properties of the skin treatment device can similarly be further improved.
