[0112] Experiment 1 According to T / JSRH 003-2023 "Hyaluronidase inhibition method for testing the anti-allergic activity of cosmetic raw materials", the hyaluronidase inhibition rate (%) of the soothing smoothie cream containing Centella asiatica extract in each embodiment and comparative example was tested.

[0113] Experiment 2 The elastase inhibition rate (%) of the soothing smoothie cream containing the Centella asiatica extract of each example and comparative example was detected.

[0114] 1. Instruments, Equipment and Reagents 1.1 Instruments and equipment: Analytical balance; Full wavelength multifunctional microplate reader.

[0115] 1.2 Reagents and consumables: Tris(hydroxymethyl)aminomethane (AR); Concentrated hydrochloric acid (GR); Elastase (30 U / mg); EGCG (epigallocatechin gallate); AAAPAN(AR).

[0116] 1.3 Test substances Sample: the soothing smoothie cream containing Centella asiatica extract of each embodiment and comparative example; Negative control: deionized water; Positive control: EGCG solution.

[0117] 3. Test method: Four groups, ABCD, were set up respectively, with 3 parallels in each group. Buffer solution, sample solution, enzyme solution and substrate were added to the 96-well plate in sequence, and the 96-well plate was placed in a low-temperature oscillating water tank at a certain temperature, and the oscillation mode was turned on. After the solution inside reacted completely, the absorbance value of each group was measured at a wavelength of 410nm.

[0118] 4. Calculation formula Where: A—is the absorbance of the reaction solution containing sample and enzyme; B—is the absorbance of the reaction solution containing sample and without enzyme; C—is the absorbance of the reaction solution containing enzyme but not sample; D—is the absorbance of the reaction solution without sample and enzyme.

[0119] The specific test data of Experiment 1-2 are shown in Table 1.

[0120] Table 1 Hyaluronidase inhibition rate (%) Elastase inhibition rate (%) Example 1 56.126 67.883 Example 2 56.431 68.124 Example 3 56.553 68.349 Comparative Example 1 49.335 36.635 Comparative Example 2 48.725 38.852 Comparative Example 3 49.053 34.127 Comparative Example 4 49.097 37.491 Comparative Example 5 48.137 33.796 According to the data comparison of each embodiment and comparative example in Table 1, the hyaluronidase inhibition rate of each embodiment is significantly higher than that of each comparative example, which proves that the soothing and anti-allergic effect of each embodiment is significantly better than that of each comparative example, and the elastase inhibition rate of each embodiment is significantly higher than that of each comparative example, which proves that each embodiment can more significantly promote the recovery of skin elasticity.

[0121] Each comparative example uses conventional plant extracts with soothing and anti-allergic effects to replace the Centella asiatica extract, Iris white iris root extract, Rosa centifolia extract, and Quercus white oak bark extract in the examples alone or in whole. Although it also has a certain soothing effect, due to the destruction of the special compound of Centella asiatica extract, Iris white iris root extract, Rosa centifolia extract, and Quercus white oak bark extract, the soothing and anti-allergic effects are significantly reduced compared with the examples, and the effect of promoting skin elasticity recovery is poor. It can be seen that only when Centella asiatica extract, Iris white iris root extract, Rosa centifolia extract, and Quercus white oak bark extract are compounded, can they simultaneously play a significant soothing and anti-allergic effect and promote skin elasticity recovery, thereby achieving a better skin repair effect.

[0122] 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.
