Problems solved by technology

[0002] There are various whitening and moisturizing products on the market, but almost all of them whiten from the perspective of inhibiting the activity of tyrosinase, which is characterized in that the production of melanin is reduced by inhibiting the activity of tyrosinase, and the generated melanin migrates to It takes a while for the surface layer of the skin, and it takes a while for the skin to age and peel off, which makes the product last longer
[0003] However, there is still no good solution for how to achieve rapid whitening, especially for people with darker skin.

Embodiment 1

[0174] The preparation of embodiment 1 composition

[0175] Compound the composition according to the formula in Table 1. In order to facilitate human body application experiments, corresponding skin creams were formulated based on the compositions in Table 1, as shown in Table 2.

[0176] Table 1. Parts by weight of the extract contained in the composition formula (calculated by the weight of the real extract)

[0177]

[0178] Table 2. Contains the skin care cream formulation of the corresponding composition in Table 1 (weight ratio, calculated in parts by weight of the essence extract)

[0179]

[0180]

[0181] Skin creams shown in Table 2 were prepared as follows:

[0182] Completely dissolve the raw materials of component A for later use;

[0183] After dispersing component B evenly, add the remaining deionized water and stir to dissolve, and heat to 80-85°C;

[0184] Mix and heat component C to 80-85°C to dissolve completely;

[0185] Pump component A into...

Embodiment 2

[0187] Embodiment 2 whitening effect test

[0188] Efficacy evaluation method: Select 24 testers with darker skin color, determine the application area, test the melanin content of the application area according to the product tested in the area, calculate the average value (all the results below are the average value) to get the initial value, and then test The results are calculated averages. Apply the skin cream once a day and use the product continuously for 3 months. The skin melanin was tested by using the MPA580 skin tester produced by CK Company of Germany on 0 day, 7 days, 14 days, 28 days, 56 days and 84 days respectively.

[0189] The result is as figure 1 , Table 3 and figure 2 shown.

[0190] Table 3. Melanin test results

[0191]

[0192] It can be seen from the results that under the action of the composition of the present invention (Example), the reduction rate of melanin is significantly higher than that of the comparative example; and the whitening ...

Embodiment 3

[0198] Embodiment 3 moisturizing effect test

[0199] Moisture retention evaluation method: select 24 trial persons, select three different areas on the inside of the arm, apply the samples of embodiment 1-3 shown in 0.1g table 2 to the hand use area, before smearing (test different people's skin according to the use position) skin moisture content and calculate the average value), 30min, 1h, 2h, 4h, 8h after application to detect the skin moisture content (average value). The average value of the test is the skin water content using the MPA580 skin tester produced by CK Company in Germany, and the water loss rate is calculated.

[0200] The result is as image 3 and Figure 4 shown.

[0201] The results show that the composition of the present invention also has good moisturizing properties.
