The test principle is as follows: the principle of the capacitance method is that the capacitance value of the skin is different according to the different water contents of the skin, and the observation parameter can represent the skin moisture value.
Test environment: the test environment temperature is 22+/-1 ℃, the humidity is 50+/-5%, and the real-time dynamic detection is carried out.
Test object: active volunteers 170 (randomized into 17 groups of 10 persons each) aged between 25-35 years (except pregnant or lactating women); the basis value of the measurement significance of the forearm test area capacitance method skin moisture is 15-100; patients with no serious systemic disease, no immunodeficiency or autoimmune disease; the prior skin care cosmetics have no serious allergic history; hormonal drugs and immunosuppressants have not been used for a month; those who did not participate in other clinical trials; the tested medicines are used according to the regulations and the data are complete; all volunteers should fill in informed consent prior to testing.
The testing steps are as follows:
preparation before testing: no product (cosmetic or topical medicine) can be used 3 days before the test site. Prior to the experiment, the subjects were required to agree to clean the forearm inner test of both hands and air dry. After cleaning, the measurement area marks are measured in the forearms of both hands of the subject. Before formal test, the patient should sit still in a room meeting the standard for at least 30min, cannot drink water, and the forearm is exposed and placed in a test state to be relaxed.
The testing process comprises the following steps: marking the inner sides of the left arm and the right arm of each person by 2X 2cm 2 The test areas, 3 areas are marked on the same arm, the areas are spaced 1cm apart, and the test areas are used for testing each group of samples respectively.
