The present invention comprises a starch, germinated brown rice, germinated barley, raw sugar, and a medium composed of purified water, and based on a complex yeast composed of Galactomyces candidus and Saccharomyces cerevisiae as proteolytic strains, fermentation of raw material proteins to free amino acids and AHA components It relates to a cosmetic raw material manufacturing method for extracting this contained cosmetic raw material. A method of manufacturing a cosmetic raw material for extracting a cosmetic raw material by solubilizing an insoluble protein through complex yeast fermentation, which is a technical idea proposed in the present invention, Preparing insoluble protein yolk； Impurities in the yolk using a solvent composed of 1 to 5% by weight of dichloromethane, 1 to 5% by weight of n-hexane, 1 to 15% by weight of ethyl ether, 10 to 60% by weight of alcohol, and 10 to 80% by weight of distilled water Removing some of the phospholipids to extract the raw protein； Fermentation to form a medium consisting of starch, germinated brown rice, germinated barley, raw sugar, and purified water, and fermenting the raw material protein based on a complex yeast composed of Galactomyces candidus and Saccharomyces cerevisiae having a weight ratio of 1: 1 as a proteolytic strain. Processing steps； It characterized in that it consists of a step of sterilizing the fermentation broth (culture solution) obtained after the fermentation treatment step and filtering the remaining strain to extract cosmetic raw materials. In the case of using the method of manufacturing a cosmetic raw material to extract the cosmetic raw material by solubilizing the insoluble protein through the complex yeast fermentation proposed in the present invention, there is an advantage in that it is possible to reduce the production time and input cost of ordinary cosmetic raw materials.본 발명은 전분, 발아현미, 발아겉보리, 원당, 및 정제수로 이루어지는 배지를 조성하고 단백질 분해 균주로 Galactomyces candidus 및 Saccharomyces cerevisiae로 구성되는
