Volunteers were randomly selected and left and right faces were used as test areas, with the sample of example 2 (hereinafter, both referred to as experimental area) on one side and the sample of comparative example (hereinafter, both referred to as comparative area) on the other side. According to the test section, the test samples were used by the volunteers once a day in the morning and evening, and the application amount was according to the personal use habit (the volunteers were not allowed to use cosmetics similar to the test samples on their faces during the test period). The test period was 4 weeks total, during which the volunteers did not change the brand and usage habits of daily skin care products. Data acquisition, image acquisition, was performed on the test area before (week 0), after 1 week, 2 weeks and 4 weeks of product use. During the return visit, the dispensed test sample is reweighed. The fitness evaluation is performed by a dermatologist, the evaluation taking the form of clinical observations and interviews of volunteers, and the evaluation parameters include: redness, desquamation, itching, stinging, burning sensation, and others. Data and image acquisition were tested for the following indicators, respectively: skin whiteness L value, ITA DEG value skin melanin content MI value, skin moisture content MMV value.

2. Screening criteria

Selecting conditions are as follows: (1) volunteers who meet all the conditions listed below will be enrolled in the test for values of skin whiteness L and lightness ITA ° and skin melanin content MI. The number of cases is more than or equal to 25; age 18-55 years; sex randomization; the content of melanin in the skin on the inner side of the crank arm is 160-250; the whiteness L value of the skin on the inner side of the crank arm is between 55 and 65; in the last 1 month, no other product test is performed; those without severe systemic disease, immunodeficiency or autoimmune disease; those with inactive allergic disease; the past has no history of allergy to skin care cosmetics; in the last month, hormone drugs and immunosuppressants have not been used systemically; those who did not participate in other clinical trials; the person who voluntarily participates and can finish the specified contents according to the test requirements. (2) Volunteers meeting all of the following conditions will be enrolled in the test skin moisture content MMV values. Normal subjects of 20-65 years old have random gender and the number of the subjects is more than or equal to 20; those without severe systemic disease, immunodeficiency or autoimmune disease; those with inactive allergic disease; the past has no history of allergy to skin care cosmetics; in the last month, hormone drugs and immunosuppressants have not been used systemically; those who did not participate in other clinical trials; the person who voluntarily participates and can finish the specified contents according to the test requirements.

Exclusion criteria: pregnant or lactating women; outdoor work is the main, and sun exposure cannot be avoided; during the trial period, the hormone and immune preparation medicines are applied to the whole body; those who apply anti-inflammatory drugs during the trial period; the subject is not used as intended or the data is not complete.

3. Other requirements

The test sites did not use a cosmetic similar to the test samples for at least one week of the elution period, i.e., within one week prior to the test. Skin moisture content test sites were cheek (midline of eye and alar junction) and outside canthus. The other index testing part is the cheek (the junction of the midline of the eye and the nasal alar part)

4. Data processing

When the normal distribution is satisfied, the change of the data before and after the use of the sample and the difference between the test area and the matrix area are analyzed by using the t-test method. When the non-normal distribution is met, a rank sum test is applied.
