BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 1 The test results of moisturizing effect of the products obtained from Example 1 and Comparative Examples 1-5 of the present invention are shown in FIG.

[0032] Figure 2 This is a repair test result diagram of the products obtained from Example 1 of the present invention and Comparative Examples 1-5. DETAILED DESCRIPTION

[0033] The present invention provides a plant extract composition, which is based on the plant concept and mainly contains purslane extract, and is matched with garlic extract and turmeric root extract at specific contents. The three achieve a synergistic effect in a suitable ratio.

[0034] At present, it is generally believed that:

[0035] Portulaca oleracea extract has a broad spectrum of antibacterial and anti-inflammatory effects, and can prevent and treat skin diseases such as eczema, allergic dermatitis, and contact dermatitis; it has good oxygen free radical scavenging ability, indicating that it has a significant antioxidant effect; it has good skin moisturizing properties. Portulaca oleracea contains many important metabolites and contains a variety of chemical components, such as flavonoids, alkaloids, terpenes, organic acids, and polysaccharides. Its active ingredients have good effects in anti-inflammatory, antibacterial, anti-allergic, anti-oxidation, exfoliation, repairing keratin, promoting skin healing, and inhibiting sebum secretion. It has great potential in the treatment of acne. The stratum corneum of the skin is an important structure for the skin barrier function. The decrease in the level of Caspase-14 in the stratum corneum will have a negative impact on the skin. Caspase-14 is a specific protease. Its reduction will affect the dephosphorylation process of profilaggrin, thereby reducing the production of filaggrin (FLG) in human skin. Due to the reduction of FLG content in the stratum corneum of the skin, the level of the resulting natural moisturizing factor decreases, which triggers changes in skin pH. This change can activate protease-activated receptor-2 (PAR-2), leading to a decrease in skin epidermal lipids and damage to keratinocytes, thereby destroying the skin barrier function. At the same time, the damage to the skin barrier function also increases the possibility of exogenous harmful substances invading the body, thereby aggravating the patient's condition.

[0036] Turmeric root extract has a good inhibitory effect on Pityrosporum, helps reduce dandruff, and is used to remove dandruff; it has a strong activation effect on luciferase, indicating that it has good anti-inflammatory ability and can prevent and treat various skin diseases; it inhibits ceramide enzymes, thereby maintaining the amount of ceramide in the cortex and softening the skin.

[0037] The main component of garlic extract is allicin, which has excellent antibacterial effect, broad antibacterial, strong antibacterial, insecticidal, non-toxic, no side effects, no drug residue, and anti-tumor effect. It can effectively reduce acne or eliminate acne.

[0038] In practice, when they are used alone, their moisturizing and repairing effects on the skin are not ideal and fail to achieve the expected results. However, when combined in set amounts, significant synergistic effects are achieved. They can be used to replace some commonly used polyol moisturizers, increase the diversity of cosmetics use, and especially improve moisturizing and repairing effects. In addition, they come from natural plants, which is beneficial to consumer experience.

[0039] The above scheme is further described below in conjunction with specific embodiments; it should be understood that these embodiments are used to illustrate the basic principles, main features and advantages of the present invention, and the present invention is not limited to the scope of the following embodiments; the implementation conditions adopted in the embodiments can be further adjusted according to specific requirements, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0081] 4. Test result analysis:

[0082] 1) Through data analysis, compared with before use of the product, the moisture content of the stratum corneum of the skin of Example 1 of the present invention increased significantly after use for 1h, 2h, 4h, and 8h, which increased by 55.43, 27.80, 25.72, and 22.42, respectively, indicating that the test product has a significant moisturizing effect.

[0083] 2) The moisture content of the skin stratum corneum of Comparative Example 1 increased after 1h, 2h, 4h, and 8h of use compared with before use, increasing by 46.26, 22.03, 1.1, and 0.08, respectively, but the increased values ​​were all lower than those of the raw material of the present invention, indicating that the moisturizing effect of Comparative Example 1 was worse than that of the raw material of the present invention, especially after 4h and 8h of use, which was significantly lower than that of the present invention, indicating that the long-lasting moisturizing ability of Comparative Example 1 was poor.

[0084] 3) The moisture content of the stratum corneum of the skin of Comparative Example 2 increased in part, or was lower in part, after 1h, 2h, 4h, and 8h of use compared with that before use, increasing by 55.90, 20.27, -2.33, and -1.03, respectively. The increase after 1h of use was basically consistent with that of the present invention, but the increase after 2h of use was lower than that of the raw material of the present invention, especially after 4h and 8h of use, which was lower than that before use. This shows that the moisturizing effect, especially the long-lasting moisturizing ability, of Comparative Example 2 is far inferior to that of the composition of the present invention.

[0085] 4) The moisture content of the stratum corneum of the skin of Comparative Example 3 after 1h, 2h, 4h, and 8h of use was partially increased or partially lower than that before use, increasing by 53.84, 15.67, -2.63, and -1.71, respectively. However, the increased values ​​were all lower than those of the raw material of the present invention, especially after 2h, 4h, and 8h of use, which were significantly lower than those of the present invention, indicating that the moisturizing effect, especially the long-lasting moisturizing ability, of Comparative Example 3 is far inferior to that of the composition of the present invention.

[0086] 5) The moisture content of the stratum corneum of the skin of Comparative Example 4 increased after 1h, 2h, 4h, and 8h of use compared with before use, increasing by 51.96, 27.10, 19.03, and 14.03, respectively, but the increased values ​​were all lower than those of the raw material of the present invention, especially after 4h and 8h of use, which were significantly lower than those of the present invention, indicating that the moisturizing effect, especially the long-lasting moisturizing ability, of Comparative Example 4 is much lower than that of the composition of the present invention.

[0087] 6) The moisture content of the skin stratum corneum of Comparative Example 5 increased after 1h, 2h, 4h, and 8h of use compared with before use, increasing by 45, 31.40, 21.77, and 19.37, respectively, but the increased values ​​were all lower than those of the raw material of the present invention. At 1h, the moisturizing effect was significantly lower than that of the present invention, that is, its immediate moisturizing effect was much lower than that of the present invention, and the moisturizing effect after 4h and 8h was also worse than that of the composition of the present invention, indicating that Comparative Example 5 was relatively poor in both immediate and long-lasting moisturizing effects.

[0088] 7) Comparison of the moisturizing test results of the composition of Example 1 of the present invention and Comparative Examples 1, 2, 3, 4 and 5 shows that the moisturizing effect of the composition of the present invention is better than that of a single raw material or a composition of other proportions.

However, the decrease values ​​were all lower than those of the raw material of the present invention, especially after 4h and 8h of use, the improvement effect of the transepidermal water loss rate of the skin was poor, indicating that the repair effect, especially the long-lasting repair effect, of the comparative example 1 was worse than that of the composition of the present invention.

[0105] 3) The transepidermal water loss rate of the skin in Comparative Example 2 decreased after 1h, 2h, 4h, and 8h of use compared with before use, decreasing by 2.57, 2.09, 1.09, and 0.08, respectively. However, the decrease values ​​were all lower than those of the raw material of the present invention, especially after 8h of use, there was almost no improvement effect on the transepidermal water loss rate of the skin, indicating that the repair effect, especially the long-lasting repair effect, of Comparative Example 2 was inferior to that of the composition of the present invention.

[0106] 4) The transepidermal water loss rate of the skin in Comparative Example 3 after 1h, 2h, 4h, and 8h of use was partially reduced compared with before use, and some even lost more water, which decreased by 2.72, 1.58, -0.33, and -0.29, respectively. Compared with Example 1 of the present invention, it can be seen that not only are their immediate repair effects poor, but even after 4h and 8h of use, the transepidermal water loss rate of the skin is increased, indicating that the repair effect, especially the long-lasting repair effect, of Comparative Example 3 is far worse than that of the composition of the present invention.

[0107] 5) The transepidermal water loss rate of the comparative example 4 decreased after 1h, 2h, 4h, and 8h of use compared with that before use, which decreased by 3.17, 1.73, 1.39, and 1.00, respectively. However, the decrease values ​​were all lower than those of the raw material of the present invention, indicating that the repair effect of the comparative example 4 was worse than that of the composition of the present invention.

[0108] 6) The transepidermal water loss rate of the comparative example 5 decreased after 1h, 2h, 4h, and 8h of use compared with that before use, which decreased by 4.42, 2.19, 2.07, and 1.27, respectively. However, the decrease values ​​were all lower than those of the raw material of the present invention, indicating that the repair effect of the comparative example 5 was worse than that of the composition of the present invention.

[0109] 7) Comparison of the repair test results of Example 1 of the present invention and Comparative Examples 1, 2, 3, 4 and 5 shows that the repair effect of the composition of the present invention is better than that of a single raw material or a composition of other proportions.

[0110] In summary, the moisturizing and repairing composition of the present invention is significantly superior to a single raw material or a composition of other proportions in terms of moisturizing effect, repairing effect, especially long-lasting moisturizing and repairing effect, indicating that after the raw materials of the present invention are combined in a set amount, a significant synergistic effect is obtained, and it can be used to replace some commonly used polyol moisturizers, increase the diversity of cosmetics, and especially improve the moisturizing and repairing effect. In addition, they also come from natural plants, which is beneficial to consumer experience.
