[0138] Experimental example

[0139] The performance of the samples prepared in various embodiments and comparative examples was tested:

[0140] 1. Whitening efficacy test

[0141] 1. Test materials: Natural plant whitening skin care essence cream prepared in Examples 1-4 and Comparative Examples 1-4.

[0142] 2. Test subjects: Each group selected people with sensitive skin, aged 20-45 years old, including 30 males and 30 females, and divided into 6 groups equally.

[0143] 3. Test instruments: Skin red-melanin content tester (Mexameter MX18, CK Company, Germany), skin color tester (Skin-Colorimeter CL 400, CK Company, Germany).

[0144] 4. Test method: The test subjects first cleaned their faces, and each person cleaned their faces for the same time. After the skin was dried, a 5 cm × 5 cm skin area on the cheek was selected as the test area. 1 g of the essence cream prepared in Examples 1-4 and Comparative Examples 1-4 was evenly applied to the test area on the face. The skin melanin content and skin color (ITA) after 7 days of use, 1 week of continuous use, and 4 weeks of continuous use were measured using a skin elasticity measuring instrument from German CK Company. 。 The smaller the value of skin melanin content, the lower the melanin content and the whiter the skin. 。 The value is the skin brightness, the higher the value, the brighter the skin. The test results are shown in the following table.

[0145] Table 3

[0146] Melanin content Before use Use for 7 days Use for 1 week 4 weeks of use Example 1 159.27 159.02 147.95 146.58 Example 2 158.92 157.90 146.23 145.86 Example 3 159.17 155.02 145.17 142.04 Example 4 158.82 156.86 146.58 144.65 Comparative Example 1 159.41 158.69 152.36 149.46 Comparative Example 2 157.96 157.23 151.12 148.34 Comparative Example 3 159.05 157.56 151.69 149.23 Comparative Example 4 158.63 156.98 152.39 149.75

[0147] Table 4

[0148]

[0149]

[0150] From the data of the above-mentioned Examples 1 to 4 and Comparative Examples 1 to 4, it can be seen that the skin melanin content measured by the essence cream prepared by Implementation 1 to 4 of the present application after 4 weeks of use is lower than that before use and the ITA value is higher than that before use, indicating that the skin becomes whiter. Among them, the effect of Example 3 group is the best, which is the best embodiment of the present application. It can be seen from the experimental data of the comparative example that the combination of Pterocarpus marsupium bark extract, hops (Humulus lupulus) extract, rosarox burghii fruit extract and plantain (Plantago major) seed extract can achieve a better whitening effect; each raw material has a whitening effect when used alone, but the whitening effect is not obvious, indicating that there is a synergistic whitening effect between the four raw materials, and the whitening effect is significant when used together.

[0151] Furthermore, the instruction manual is attached Figure 1 and Figure 2 The comparison diagram of Example 3 before and after use is shown. Figure 1 This is a photo of the test personnel before using the sample of Example 3; the instruction manual is attached. Figure 2 These are photos of the test subjects after using the sample of Example 3 for 8 weeks.

[0152] From the instruction manual Figure 1 and Figure 2 It can be seen from the comparison that after the subjects used the sample of Example 3 for 8 weeks, it can be clearly seen that the whitening effect is significant.

[0153] 2. Tyrosinase inhibition rate test

[0154] Take 1 g of each example and comparative example essence cream sample, add purified water to make up to 10 ml and shake well, measure the absorbance at 490 nm on an ELISA reader, and then calculate the tyrosinase inhibition rate of the sample by the formula.

[0155] Measuring instrument: TECAN SPARK 10M microplate reader

[0156] The results are shown in the following table:

[0157] Table 5

[0158]

[0159] From the data in the above table, it can be seen that the tyrosinase inhibition rate of Example 3 is the highest; the tyrosinase inhibition rates of Examples 1-4 are higher than those of Comparative Examples 1-4, indicating that the whitening skin care products of the present application, using Pterocarpus marsupialis bark extract, hops (HUMULUS LUPULUS) extract, rosa roxburghii fruit extract and plantago major (PLANTAGO MAJOR) seed extract, can achieve better whitening effects. Each raw material has a whitening effect when used alone, but the whitening effect is not obvious, indicating that there is a synergistic whitening effect between the four raw materials, and the whitening effect is significant when used together.

[0160] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
