[0002] In recent years, with the growing demand for anti-aging products, various anti-wrinkle and firming skin care products have appeared on the market. However, although traditional anti-wrinkle ingredients such as vitamin C derivatives and retinols have certain effects, they generally have problems such as strong irritation and poor long-term effects.

[0003] With the development of plant extraction technology, more and more skin care products are using natural plant extracts to replace chemical synthetic ingredients, which can effectively reduce the irritation of skin care products and have certain anti-aging effects.

[0004] However, although skin care products on the market that add plant extracts can have certain anti-wrinkle effects, the effects are relatively general and slow to take effect, which can hardly meet consumers' needs for quick wrinkle removal.

[0086] Experiment 1 According to T / AHPCA 047-2023 "Test Method for Anti-Wrinkle and Firming Efficacy of Cosmetics (Rapid Determination of Elastase Inhibition)", the elastase inhibition rate (%) of the test samples prepared from the anti-wrinkle and firming composite fermentation extracts of each embodiment and comparative example was tested.

[0087] Sample to be tested: Take 20g of anti-wrinkle and firming composite fermentation extract and 80g of deionized water, mix well to obtain the sample to be tested.

[0088] Experiment 2 According to T / SHRH 006-2018 "Experimental Method for Scavenging Cosmetics Free Radicals (DPPH)", the DPPH free radical scavenging rate (%) of the test sample prepared from the anti-wrinkle and firming composite fermentation extract of each embodiment and comparative example was detected.

[0089] Sample to be tested: Take 20g of anti-wrinkle and firming composite fermentation extract and 80g of deionized water, mix them evenly to obtain the sample to be tested.

[0090] Experiment 3 According to T / GDCA 006-2021 "Test method for inhibition of tyrosinase activity by cosmetic raw materials (in vitro method)", the tyrosinase inhibition rate (%) of the test samples prepared from the anti-wrinkle and firming composite fermentation extracts of each embodiment and comparative example was tested.

[0091] Sample to be tested: Take 20g of anti-wrinkle and firming composite fermentation extract and 80g of deionized water, mix well to obtain the sample to be tested.

[0092] The specific test data of Experiments 1-3 are shown in Table 1.

[0093] Table 1 According to the data comparison of each embodiment and the comparative example in Table 1, it can be obtained that the elastase inhibition rate, DPPH free radical scavenging rate, and tyrosinase inhibition rate of each embodiment are significantly higher than those of each comparative example. It can be seen that each embodiment has more significant anti-wrinkle, anti-aging, and whitening effects, can more comprehensively and efficiently care for the skin, and restore the skin to health faster.

[0094] In Comparative Examples 1-5, other plant raw materials with anti-wrinkle effects are used to replace the Agaricus bisporus, Rubia cordifolia, Lythrum sachalinensis, and Euphorbia cerana in the embodiments alone or in whole. Although they can also have certain anti-wrinkle and anti-aging effects, the special compound of Agaricus bisporus, Rubia cordifolia, Lythrum sachalinensis, and Euphorbia cerana is destroyed, resulting in a significant decrease in the effect of the various active ingredients cooperating with each other, resulting in a more obvious decrease in the anti-wrinkle and anti-aging effects compared with the embodiments, and the whitening effect is poor, making it difficult to achieve a better whitening effect.

[0095] In Comparative Examples 6-9, other fermentation bacteria are used alone or in whole to replace the Jedinseiberlindner Saccharomyces cerevisiae, Lactobacillus paracasei, and Bacillus amyloliquefaciens in the embodiments. Since the composite system of Jedinseiberlindner Saccharomyces cerevisiae, Lactobacillus paracasei, and Bacillus amyloliquefaciens is destroyed, the effect of the fermentation product and the active ingredient is reduced, resulting in the anti-aging, anti-wrinkle, and whitening effects being better than those of Comparative Examples 1-5, compared with the embodiments, the anti-aging, anti-wrinkle, and whitening effects are all reduced.

[0096] It can be seen that only when Agaricus bisporus, Rubia cordifolia, Lythrum sachalinensis, and Euphorbia cerevisiae are compounded and fermented by Saccharomyces cerevisiae, Lactobacillus paracasei, and Bacillus amyloliquefaciens, can the obtained extract exert very significant anti-wrinkle, anti-aging, and whitening effects.

[0097] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
