[0046] Testers with dry skin (dry skin), oily skin (oily skin), and neutral skin (neutral skin) without skin diseases were each divided into 6 groups, with one person in each group. The first 3 groups used the whitening essence prepared in Examples 1 to 3 respectively, and the last 3 groups used the essence in Comparative Examples 1 to 3 respectively. During the use period, it was used once in the morning and once in the evening. When using, evenly apply the essence on the face and gently pat for 2 minutes to allow the essence to be fully absorbed by the skin, and use it continuously for one month. Then, use the CM825 probe to detect the melanin index of the skin of each group and take the average value. At the same time, use the YN-19 skin moisture tester to measure the skin moisture content of each group and take the average value. The results are shown in Table 1.
