The difference from experimental example 1 is that: the whitening composition was the whitening composition prepared in comparative example 3.
Blank control group
The difference from experimental example 1 is that: the whitening composition was replaced with an equivalent amount of humectant.
Experiment 1
130 female volunteers of similar skin tone were randomly selected, aged 25-55 years, and the volunteers were randomly divided into 13 groups of 10 persons each. The volunteers respectively and correspondingly use the whitening essence or the whitening water prepared by the experimental example, the comparative experimental example and the blank control group after face cleaning in the morning and evening, the whitening essence or the whitening water is uniformly smeared on cheeks at two sides, the usage amount of each time is 5g, the skin care product is continuously used for 28 days, and no other skin care products are used in the test process. Skin melanin content (MI value) of volunteers before, after 7 days, after 15 days, and after 28 days of use was measured using a melanin tester from CK company in germany. The average of the test results of the volunteers of the same group was calculated and recorded.
Among them, the lower the measured melanin content (MI value), the less melanin the skin contains, and the brighter the skin is.
Experiment 2
After volunteers continuously use for 28 days, salicylic acid is added into the whitening essence or the whitening water prepared in the experimental example, the comparative experimental example and the blank control group, the addition amount of the salicylic acid is 0.5% of the mass of the whitening essence or the whitening water, after uniform mixing, the volunteers respectively take 1g of the whitening essence or the whitening water corresponding to each group after adding the salicylic acid, uniformly apply the whitening essence or the whitening water on the left cheek, and record the number and the condition of people with skin itch or allergy in each group.
The test data of the above experiment are shown in Table 1.
TABLE 1
According to the comparison of the data of the hollow white control group and the data of the comparison experimental example 1 in the table 1, the white control group and the data of the comparison experimental example 1 are obtained, and by adding the radix arnebiae seu lithospermi extract and the paecilomyces farinae extract simultaneously for synergistic compounding, although the whitening effect of the whitening composition is better improved to a certain extent, the content of melanin in the skin is reduced, the melanin is removed, and meanwhile, the skin barrier is easily damaged, so that the skin is easily itchy or allergic when the skin is subjected to slight stimulus.
According to the data comparison of comparative experimental examples 1 to 3 in table 1, by adding apple root extract, while being advantageous to slightly alleviating damage of the extract of arnebia root and extract of paecilomyces meretricis on skin barrier to some extent, the whitening effect of the extract of arnebia root and extract of paecilomyces meretricis is slightly affected at the same time; the addition of the pomegranate peel extract is favorable for further inhibiting the activity of tyrosinase, so that the whitening effect of the whitening composition is better, but the skin barrier is damaged to a certain extent, and the skin is more sensitive easily.
According to the comparison of the data of the experimental example 1 and the data of the comparative experimental examples 1-3 in the table 1, the damage of the radix arnebiae seu lithospermi extract and the paecilomyces farnesii extract on the skin barrier in the process of removing melanin can not be relieved by independently adding the apple root extract or by independently adding the pomegranate peel extract, and the skin barrier is not easily reconstructed while the whitening effect of the whitening composition is better promoted only by adopting the synergistic effect of the apple root extract and the pomegranate peel extract, so that the skin is not easily affected by itch or red swelling when being slightly stimulated.
According to the data comparison of experimental examples 3 to 6 in table 1, the whitening effect of the whitening composition is further promoted by adding nicotinamide, ellagic acid and glutathione, and at the same time, the skin barrier reconstruction is not easily affected, so that the skin is not easily itchy or red and swollen when being slightly stimulated.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
