PURPOSE: A cosmetic material prepared by a cosmetic composition using a fermented rice bran liquid is provided to effectively treat dermatitis, thereby creating value added and developing related technology by developing an external use skin formulation.CONSTITUTION: A method for preparing a fermented rice bran extract comprises the steps of: putting 35-45 wt% of rice bran to a jar uniformly pouring 55-65 wt% of sugar water containing sugar and purified water to the jar so as to have a sugar content of 45-55 brix sealing the opening of the jar with Hanji (Korean traditional paper) fermenting the content in the jar at 15-25°C for 80-100 days to extract active ingredients of rice bran filtering the fermented material using a non-woven fabric to collect a fermented liquid adding useful microorganisms such as Monascus pilosus and Aspergillus oryzae in 0.1-5 wt% of the fermented liquid sealing the opening with Hanji and fermenting at 25-35°C for 10-30 days to generate physiologically active substances and filtering the fermented liquid using filter paper of 350-550 mesh twice or three times. A cosmetic material contains 0.01-30 wt% of the fermented rice bran extract.COPYRIGHT KIPO 2013[Reference numerals] (AA) Diastatic fermentation process (BB) Putting 35-45 wt% of rice bran and 65 wt% of sugar water having a sugar content of 45-55 brix to a jar and fermenting the content in the jar at 15-25°C for 80-100 days (CC) Microorganism fermentation process (DD) Adding useful microorganisms such as Monascus pilosus and Aspergillus oryzae in 0.1-5 wt% of the fermented liquid and microorganism fermenting at 25-35°C for 10-30 days (EE) Filtering process (FF) Filtering the fermented liquid using filter paper of 350-550 mesh twice or three times to foam rice bran fermenting extract of pure liquid본 발명은 쌀의 도정 과정에서 발생하는 미강을 저온에서 당화 발효 및 효소 발효과정을 통하여 미강의 유효성분을 최대한 추출한 발효액을 제조하고, 이 미강 발효액에 함유된 풍부한 아미노산 및 여러 생리 활성기능을 통하여 인체의 피부장벽을 강화함으로써 건조 피부, 노화 피부의 기능을 정상화시키기 위한 화장료 조성물을 제조하
