[0045] Comparative Example 1

[0046] The control essence used in this comparative example is the essence with the national makeup special number G20212367.

[0047] Comparative Example 2

[0048] The control essence used in this comparative example is the essence with the national makeup special number G20211563.

[0049] Example and Comparative Example Essence Effect Test

[0050] The testers with dry skin (dry skin), oily skin (oily skin) and neutral skin (medium skin) without skin diseases were divided into 5 groups, with one person in each group. The first 3 groups used the whitening essences prepared in Examples 1 to 3, respectively, and the last 2 groups used the essences of Comparative Examples 1 to 2, respectively. During use, use it once in the morning and once in the evening. When using, apply the essence evenly on the face and gently pat for 2 minutes to allow the essence to be fully absorbed by the skin. Use it continuously for one month. Then, use the CM825 probe to detect the skin condition of each group, and measure the melanin index of each group of skin using the following formula:

[0051]

[0052] Among them, MI is the melanin index, ir is infrared light, rt is the reflected light corresponding to each light, and r is red light. At the same time, the skin moisture content of each group was measured using a YN-19 skin moisture tester. The results are shown in Table 1.

[0053] Table 1 Comparison results of examples and comparative examples

[0054]

[0055] It can be seen from Table 1 that when the whitening essence cream prepared by the present invention is used by people with different skin types, the melanin index is at a lower level than that of the essences currently available on the market, and the skin moisture content is at a higher level than that of the essences currently available on the market. Therefore, the whitening essence prepared by the present invention can be suitable for different skin types, and has good whitening and moisturizing effects on different skin types.
