(1) Objective evaluation-instrumental testing

Through the objective evaluation of the instrument test result, on the 28 th day using the product, the water content of the stratum corneum of the test part of the test subject in the research is obviously increased compared with that before the product is used, and the product is prompted to have a certain moisturizing effect on the skin of the test part of the test subject in the research.

On the 14 th day and the 28 th day after the product is used, the skin heme concentration and the red area ratio of the test part of the test subject in the research are obviously reduced compared with those before the product is used, and the product is prompted to have certain repairing and relieving effects on the skin redness of the test part of the test subject in the research.

The measured value of the skin glossiness of the test part of the study subject is obviously increased compared with the measured value before use on the 14 th day and the 28 th day by using the product, which indicates that the product has a certain improvement effect on the skin glossiness of the test part of the study subject.

The results obtained using the sensitive skin typing questionnaire are shown in fig. 2, with 25 persons having moderate sensitivity and 7 and 3 persons having mild and severe sensitivity, respectively.

The water content of the skin stratum corneum of a subject is tested by using a CK Corneometer CM825 tester for the water content of the skin stratum corneum, and the higher the measured value is, the higher the water content of the skin stratum corneum of a test part is indicated. It can be observed that the skin moisture content of the subject gradually increases with the time of application of the product, and the results are shown in fig. 3. As can be seen from fig. 3, the average skin moisture content of the subjects, before use, was 62.10%, and increased to 69.35% after 28 days of use.

Skin permeability barrier function is indirectly reflected by the loss of epidermal water, and the value of sensitive skin is often increased. The research adopts TM300 for testing, the lower the measured value is, the lower the water loss of the skin at the tested part through the epidermis is, the better the function of the indirect reaction epidermal permeability barrier is, and the result is shown in figure 4. As shown in figure 4, after the product is used for 14 days, the water loss value of the skin through the epidermis is reduced, and the product is proved to have certain repairing effect.

After the skin of the test part is imaged by Alltcra3Dcs, the heme concentration is obtained by software analysis. Higher measurements indicate higher concentrations of hemoglobin in the skin at the test site, and the results are shown in FIG. 5. The statistical results of fig. 5 show that: subject test site skin at D ₁₄ 、D ₂₈ Hemoglobin concentration and D ₀ The comparison was reduced and statistically different (P < 0.05).
