Description

Technical Field

[0001] The present invention relates to the technical field of daily chemical products, and in particular to a composition with the functions of repairing skin base and moisturizing and locking moisture, as well as a preparation method and application thereof. Background Art

[0002] The skin is the organ that is most directly in contact with the outside world and covers the entire body surface. In recent years, people have become increasingly aware of the importance of skin hydration. The stratum corneum on the surface of the skin has water absorption and barrier functions. The amino acids, lactates and sugars contained in the stratum corneum keep the stratum corneum at a certain water content to keep the skin moist. Dehydration of the skin will make the skin dry, not moisturized, and feel tight. The long-term consequence is skin aging, wrinkles, spots, and become rough, dull, and lack of elasticity.

[0003] Furthermore, the skin is the human body's natural barrier. Healthy skin effectively locks in moisture, maintaining good elasticity and radiance. However, if the skin barrier is damaged, moisture evaporates, leading to dry skin and a range of skin problems, such as skin aging, atopic dermatitis, eczema, psoriasis, ichthyosis, and photodermatitis. A damaged skin barrier also increases skin sensitivity, exacerbating the damage. Therefore, only healthy skin can effectively retain moisture and prevent various skin problems.

[0004] Therefore, in the current skin care work, it is necessary to develop a skin care product that can repair the skin barrier function, moisturize and lock in water, so as to enhance the skin's water circulation and skin barrier function, which is of practical significance.

[0089] Test Example 2

[0090] The skin base repairing and moisturizing and water-locking compositions prepared in Examples 1-6 and Comparative Examples 1-6 were used to prepare toners according to the toner formula and process of Application Example 1, and a moisturizing and water-locking test was performed;

[0091] Experimental Method: 120 volunteers with dry skin, 60 men and 60 women aged 20-35, were randomly divided into 12 groups, with 10 participants in each group. The subjects were asked not to use cosmetics or topical medications for the first 15 days. Before the test, the subjects washed their faces and sat in a relaxed state for 30 minutes 2 hours after washing. The water content of the same facial area of the subjects was tested using a skin moisture content tester. Afterwards, the subjects used toners prepared from the skin-repairing and moisturizing compositions prepared in Examples 1-6 and Comparative Examples 1-6 once daily, using essentially the same amount. The skin was used continuously for one month, and the water content was tested on the 15th and 30th days. The test results are shown in Table 2.
