A method for preparing a liquid component of basic cosmetics is provided to obtain the liquid component without using a chemical synthetic material by utilizing metabolism, fermentation, and nutrition decomposing capability of microorganism, thereby being applied to organic cosmetics. The method comprises the steps of: (a) a first culturing step; and (b) a second culturing step. The first culturing step comprises the steps of: (a-1) mixing 100 kg of volcanic deposit crushed soil, 5 kg of rice bran, 5 kg of corn powder, 2 kg of chitosan powder, 1 kg of gemmule and 1 kg of molasses and then adjusting the moisture content thereof into 25-30%; (a-2) after inoculating Streptomyces griseus, Aspergilus niger, and Saccharomyces cerevisiae into the organic culture medium obtained from the step(a-1), ventilating it with agitating at an initial temperature of 30 deg.C under fermentation temperature of 28-30 deg.C to culture spawn; and (a-3) granulating the culture medium during the agitation. The second culturing step comprises the steps of: (b-1) after preparing a culture medium composition same as the first culturing using mineral water as an aqueous solution, heating the solution to a temperature of 30-35 deg.C and treating it with continuous oxygen aeration for 48 hours; (b-2) after filtering the solution obtained from the step(b-1) using a filtration filter having a size of 3 micrometers, treating it at a temperature of 30-35 deg.C for 5-7 days with oxygen circulation aeration; and (b-3) after filtering the solution obtained from the step(b-2) with a filter having a size of 0.5 micrometer, treating it with 50 ppm ozone per minute for resterilization.
