The method of the automatic skin care application device according to any one of claims 1 to 9, characterized in that: The method comprises the following steps: Step 1: Start the first motor to drive the bidirectional threaded rod to rotate, and the bidirectional threaded rod drives the two driving claws to approach each other, so that the two driving claws are respectively inserted into the two limit grooves, so that the connecting frame is installed on the mechanical arm, and the spray head can be driven to move by the mechanical arm, so as to facilitate the spraying care of different positions of the back skin; Step 2: The second motor drives the driving screw to rotate. Since the driving screw is threadedly connected to the moving block, the driving screw can drive the moving block to move, thereby realizing liquid storage and liquid spraying; Step 3: When the moving block moves up and down, the liquid spraying pipe and the nozzle can be driven to rotate, so that the nozzle rotates while spraying liquid. At the same time, the stirring piece, the stirring shaft and the stirring plate thereon can be driven to rotate to stir the skin care liquid to prevent the skin care liquid from settling. Step 4: Start the telescopic rod, and the piston plate squeezes the gas in the gas cylinder through the outlet pipe. The gas drives the liquid outlet pipe, the liquid spray pipe and the residual skin care liquid in the nozzle to spray out, thereby cleaning the residual liquid in the nozzle.
