Embodiment 1
[0029] Embodiment 1, preparation of slender geranium alcohol extract
[0030] Take slender geranium hay, wash, dry, and pulverize into fine powder; add 55% ethanol solution according to the ratio of 1g:15ml of solid to liquid, reflux extraction twice, combine the extracts, remove ethanol under reduced pressure, and concentrate to obtain .
Embodiment 2
[0031] Example 2. Preparation of a composition that can improve acne marks and scars
[0032] S1. According to the added volume of the slender geranium extract being 22% of the volume of the yeast medium, mix the slender geranium extract with the yeast medium, and sterilize at 121° C. to obtain a primary fermentation substrate;
[0033] S2. Inoculate the above-mentioned primary fermentation substrate with Candida CGMCC2.1763 cultured on a shaking table in advance, so that the yeast concentration in the substrate is 8×10 6 cfu / ml, for fermentation, after the fermentation, take the fermentation liquid, sterilize, and let it stand for cooling to obtain the primary fermentation active substance. The fermentation parameters are: pH value is 4.3-5.8; stirring speed is 100-200rpm; 4VVM; fermentation temperature is 28°C; fermentation time is 4 days;
[0034] S3. According to the added volume of the primary fermentation active substance being 15% of the volume of the C. nigriscens cul...
