In the skin cleansing device 1 of the present embodiment, baking soda was used as the granules and water was used as the liquid. Further, a compressed gas (pressure: 0.2 MPaG) was used as the gas in which the granules were mixed. Washing was performed for 20 seconds using the skin washing device 1 of the present embodiment.

In the comparative example, shampoo and hand-washed with lathering fingers. In the comparative example, hand washing was performed for 20 seconds.

From the evaluation result of FIG. 8, the skin washing device 1 according to the present embodiment was able to wash from the surface of the plate to the inside of the hole. On the other hand, in the comparative example of FIG. 9, the inside of the hole could not be cleaned. Furthermore, in the comparative example, artificial dirt was stretched laterally from the surface of the hole.

As described above, by using the skin cleaning device 1 according to the present embodiment, it is possible to effectively clean the dirt such as sebum in the pores.

<Action / effect>
The skin cleaning device 1 according to the present embodiment can clean the skin by physically removing the dirt adhering to the pores or the like by the granular material mixture gas. As described above, in the skin cleaning method using the skin cleaning device 1, since dirt is physically removed, it is not necessary to use a liquid that irritates the skin or hair (hair), such as an alkaline solution, and the skin. Can gently cleanse the skin.

In addition, the skin cleaning device 1 according to the present embodiment can wash away dirt and particles removed by the fluid mixed gas by simultaneously directing the granular mixed gas and the liquid (water) toward the skin.
