[0002] Cosmetics are one of the important products used to repair the skin. With the development of technology, cosmetics are no longer a luxury item, but have become a mass consumer product with a large consumer group. Therefore, the large consumer group has also brought about the diversity of skin problems. Targeted solution to skin problems is the development direction of cosmetics.

[0003] Acne is mainly a skin problem caused by the accumulation of oil in the skin's hair follicles, which leads to the growth of bacteria. After the acne subsides, it is easy to leave acne marks on the skin, which seriously affects the appearance. With the acceleration of the social pace, modern young people have a higher frequency of acne, resulting in acne removal, whitening, and acne mark removal becoming an urgent need for consumers.

[0004] Whitening ingredients and antibacterial ingredients are added to existing cosmetics to achieve certain acne-removing and whitening effects. However, both the whitening and acne-removing effects are relatively general and take effect slowly, which is difficult to meet the needs of consumers. Therefore, there is still room for improvement.

[0104] Experiment 1 A number of volunteers, female, aged 25-35, with initial melanin content of facial skin between 300-400, were recruited. The melanin content was tested using the MX18 melanin tester from the German CK company and recorded as the initial melanin content.

[0105] Ten people were divided into a group and used the test samples prepared from the compositions with whitening and acne scar removal effects of the embodiments and comparative examples once a day in the morning and evening, 3 ml each time, and evenly applied the test samples on the face after washing with a disposable face towel and clean water.

[0106] Use it continuously for 15 days. On the morning of the 16th day, clean your face with a disposable face towel and clean water, and then use the MX18 melanin tester from German CK company to test the melanin content again. Record it as the melanin content after 15 days of whitening.

[0107] Sample to be tested: 5 g of the composition with whitening and acne scar removal effect of each embodiment and comparative example and 95 g of deionized water are mixed evenly to prepare the sample to be tested.

[0108] The experimental data of each group were averaged.

[0109] Experiment 2 The test was conducted with reference to the test methods for bactericidal performance, antibacterial performance and stability of products in Appendix C of GB / T 15979-2002 "Sanitary Standards for Disposable Sanitary Products". The test samples were prepared using the compositions with whitening and acne scar removal effects of the embodiments and comparative examples. The action time was 20 minutes, the test was repeated 10 times, the test temperature was 26.7°C, and the relative humidity was 69%.

[0110] Sample to be tested: 5 g of the composition with whitening and acne scar removal effect of each embodiment and comparative example and 95 g of deionized water are mixed evenly to prepare the sample to be tested.

[0111] Test strain: Propionibacterium acnes, ATCC 11827.

[0112] Experiment 3 The test samples prepared from the compositions with whitening and acne scar removal effects of the embodiments and comparative examples were subjected to anti-wrinkle and firming effect tests.

[0113] 1. Test Principle The biochemical method for anti-wrinkle and firming efficacy mainly characterizes the anti-wrinkle and firming efficacy by evaluating the inhibition rate of the active substance on elastase. Elastase is the most important enzyme in the matrix metalloproteinase family, which is mainly synthesized and secreted by fibroblasts and can degrade elastin in the skin, leading to skin aging.

[0114] 2. Instruments, Equipment and Reagents 2.1 Instruments and equipment: Analytical balance; Full wavelength multifunctional microplate reader.

[0115] 2.2 Reagents and consumables: Tris(hydroxymethyl)aminomethane (AR); Concentrated hydrochloric acid (GR); Elastase (30 U / mg); EGCG (epigallocatechin gallate); AAAPAN(AR).

[0116] 2.3 Test sample: 5g of the composition with whitening and acne scar removal effect of each embodiment and comparative example and 95g of deionized water are mixed evenly to prepare a test sample; 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 experimental data of Experiments 1-3 are shown in Table 1.

[0120] According to the data comparison of each embodiment and the comparative example in Table 1, after 15 days of use, the melanin content of each embodiment is lower than that of each comparative example. It can be seen that each embodiment has a more significant whitening effect and can achieve a rapid whitening effect.

[0121] The average antibacterial rate of Propionibacterium acnes in each embodiment is higher than that in each comparative example. It can be seen that each embodiment has a stronger antibacterial effect, can quickly sterilize, make acne recover faster, and can achieve the effect of rapid acne removal.

[0122] The elastase inhibition rate of each embodiment is significantly higher than that of each comparative example. It can be seen that each embodiment can better restore the elasticity of the skin, thereby better smoothing acne marks and achieving the effect of quickly removing acne marks.

[0123] Each comparative example uses an extract with whitening and antibacterial effects to replace the Centella asiatica extract, willow bark extract, Phellodendron chinense bark extract, Houttuynia cordata extract, and Rubus idaeus extract in the examples alone or in whole. Since the special compound system of Centella asiatica extract, willow bark extract, Phellodendron chinense bark extract, Houttuynia cordata extract, and Rubus idaeus extract is destroyed, the synergistic effect cannot be exerted, resulting in a certain decrease in the whitening and antibacterial effects, and a significant decrease in the effect of inhibiting elastase, making it difficult to achieve the effects of whitening, acne removal, and acne mark removal at the same time.

[0124] 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.
