With the progress of times and scientific technology, the cosmetic industry has undergone countless changes and innovations, and the demand of consumers for green, safe and functional cosmetics is increasing, so that the core competitiveness of cosmetic products is gradually focused on safety and efficacy. The biological fermentation technology is used as an emerging biological technology, uses certain functions unique to microorganisms, adopts modern biological engineering technology means, and is used for producing products on a large scale or directly applying the microorganisms to product terminals, so that the biological fermentation technology is gradually applied to the field of cosmetics, and the safety and the efficacy of the cosmetics are greatly improved. The biological fermentation technology is applied to the field of cosmetics, and has the advantages that on the one hand, microorganisms contain certain enzymes, and substances such as cellulose, hemicellulose and the like in cell walls and cell interstitials of plant raw materials can be degraded, so that plant cells are broken, cell gaps are increased, the mass transfer resistance of active ingredients in the extraction medium from the cells is reduced, and the extraction rate of the active ingredients is greatly improved. On the other hand, the biological fermentation process can enrich the active ingredients of the raw materials, and generate new effects. Compared with traditional physical, chemical and other extraction means, the biological fermentation technology can convert and modify the effective components to a greater extent by purposefully selecting strains, controlling fermentation conditions, regulating metabolic pathways and explaining the efficacy mechanism of fermentation products, thereby improving and optimizing the properties of the original efficacy components; the mild conditions of microbial transformation can also minimize the damage to the active ingredients during fermentation, thus promoting the efficacy of the cosmetic. In addition, natural plant resources are rich in nutrition components, but the components are complex, and the problems of excessive heavy metal, pesticide residues and the like exist, so that the application and development of the natural plant resources are limited. The microbial fermentation technology is adopted to carry out biological conversion, so that the toxicity of the original toxic substances can be reduced, and the use safety is ensured. Saussurea involucrata is a plant of saussurea of Compositae, and is also called herba Saussureae Involueratae, and flos Clerodendri Bungei. The characteristic of the saussurea involucrata adapting to the alpine environment is that the saussurea involucrata is formed under the conditions of severe cold and drought of the alpine for a long time, and the special survival habit and the growth environment bring about wide pharmacological action and precious practical value of the saussurea involucrata.
The application of herba Saussureae Involueratae in cosmetics is mainly divided into two types, one is the use of extract, and the other is the fermentation of extract.
Specifically, the following documents show:
Prior art 1: CN110680775A discloses a whitening, moisturizing and moisturizing essence liquid, which comprises the following components in parts by weight:
100-150 parts of damascus roseus flower water, 5-10 parts of ophiopogon root extract, 0.1-2 parts of yeast extract, 1-5 parts of lysate of fermentation products of two-split yeast, 1-5 parts of ganoderma lucidum extract, 3-10 parts of snow lotus herb extract, 1-5 parts of tremella fruit body extract, 5-10 parts of glabrous greenbrier rhizome extract and 0.5-1.5 parts of preservative.
The technology utilizes the snow lotus herb extract to be added into cosmetics for utilization, and has the effects of whitening, moisturizing and supplementing water.
Prior art 2: CN111728910a discloses a fermented extract of blueberry and snow lotus, a preparation method and application thereof. The fermented extract of the blueberries and the snow lotus flowers is obtained by fermenting the blueberries and the snow lotus flowers together by using saccharomyces cerevisiae.
The technology utilizes the snow lotus herb to ferment, and the obtained ferment extract is utilized, and has the effects of moisturizing and resisting oxidation.
Prior art 3: CN111249218B discloses a snow lotus fermentation stock solution, a preparation method and application thereof, wherein the method comprises the steps of mixing snow lotus powder, zymophyte bacterial liquid, glucose and water to obtain an initial system, wherein the zymophyte bacterial liquid is mixed bacterial liquid of lactobacillus plantarum and streptococcus thermophilus, regulating pH to 4.5-6.5 for fermentation, fermenting at 35-43 ℃ for 12-60 hours to obtain fermentation liquid, sterilizing the fermentation liquid, centrifuging, and collecting supernatant to obtain the snow lotus fermentation stock solution.
The technology utilizes the snow lotus herb to ferment, and the obtained ferment extract is utilized, and has the functions of antioxidation and whitening.
The technical problem to be solved by the scheme is as follows: how to enrich the efficacy of the snow lotus herb in cosmetics and improve the corresponding efficacy effect.
Disclosure of Invention
The invention aims to provide a preparation method of a snow lotus fermentation product, which adopts tremella extract, yeast extract and snow lotus powder for mixed fermentation, and the obtained fermentation product has the functions of tightening, relieving and anti-wrinkle, and simultaneously has good safety, mildness and no irritation.

It should be noted that: during the hyaluronidase assay, some data results which are more difficult to understand were presented, and the inhibition effect of comparative example 5 was superior to that of example 5, which was not expected during the experimental run. Or it is hypothesized that fermentation does not favor an increase in hyaluronidase inhibition.
At the same time, the inhibition effect of example 7 is superior to that of examples 5 and 6, which is also difficult to understand, and a reasonable mechanism explanation cannot be given for the result temporarily through the discussion of the meeting of the detection personnel.
It can be seen from examples 5 and comparative examples 1 to 3 that the tremella extract does not take absolute advantage of the inhibition of hyaluronidase.

1. The examples are generally superior to the comparative examples in terms of DPPH radical scavenging rate, elastase inhibition rate;
2. the individual test groups had some uncertainty in terms of hyaluronidase inhibition, but it is clear that fermentation with a single strain would be superior to that with a complex strain.

In subsequent experiments, research and discussion of this aspect will be conducted; 10 to 50% by weight of the essence shown in comparative example 5 was added on the basis of examples 1 to 5, in particular on the basis of example 4.
