The invention provides a skin-care liquid preparing unit comprising: a main container 2 which contains raw water; a cartridge container 3 which is placed in the main container 2, and which contains different kinds of cation exchange resins; and a sprayer 4 which is attached to an upper end mouth portion 6 of the main container 2, and which has a suction pipe 17 connected to an upper portion of the cartridge container 3. The unit is configured so as to pass the raw water in the main container 2 through the cartridge container 3 from a lower portion of the cartridge container and spray the water from the sprayer 4. In the unit, in order to easily prepare skin-care liquid of a pH value that is useful for moisture retention and health of the skin, an Na type or K type cation exchange resin layer 13 and an H type cation exchange resin layer 11 are formed to be arranged in upper and lower positions in the cartridge container 3.
