Green tea symbiotic fermentation liquor with anti-oxidation, oil-control and anti-wrinkle effects as well as preparation method and application of green tea symbiotic fermentation liquor

The invention discloses green tea symbiotic fermentation liquor with anti-oxidation, oil-control and anti-wrinkle effects as well as a preparation method and application of the green tea symbiotic fermentation liquor, and belongs to the technical field of cosmetics. The preparation method of the green tea symbiotic fermentation liquor comprises the following steps: firstly, preparing green tea into green tea powder, then inoculating activated compound bacteria into a fermentation substrate containing the green tea powder, fermenting, and filtering a mixed solution obtained after fermentation to obtain filtrate, namely the green tea symbiotic fermentation liquor, wherein the compound bacteria comprise saccharomyces cerevisiae, lactic acid bacteria and aspergillus brazilis, and the inoculum size of the compound bacteria is 3-9%; the mark of fermentation ending is that the pH value of the mixed solution is reduced to 3.0-4.5. Saccharomyces cerevisiae, lactic acid bacteria and aspergillus brazilis are adopted to
