A water dermabrasion and skin care device includes a water dermabrasion handpiece, a BIO+PDThandpiece,a Bipolar handpiece, a negative pressure air compressor, a two-way flow control valve,a skincare container and a waste water tank.

The water dermabrasion handpiece is formed with a water outlet joint and a water inlet joint, which is connected to a water outputting end of the two-way flow control valve, while the water outlet joint is connected to the negative-pressure air compressor. One water inputting ends of the two-way flow control valve are connected to a pure water bottle. When the two-way flow control valve is switched to a dermabrasion position or a skincare position, the negative-pressure air compressor can be started to generate a vacuum suction, which will suck pure water from the pure water bottle to flow into the water dermabrasion for executing a dermabrasion operation or a skincare operation.
