Description

Technical Field

[0001] The present invention belongs to the technical field of skin care products, and in particular relates to a skin care composition and a preparation method and application thereof. Background Art

[0002] Ultraviolet rays are divided into two types: UVB and UVA. UVB is outdoor ultraviolet rays. After entering the skin, it will cause a certain degree of damage to skin cells. Some injured skin cells will release chemicals, stimulate capillaries, and cause congestion, which is usually referred to as sunburn. The sun protection value SPF is calculated based on the multiple of the time it takes for the skin to turn red after UVB irradiation. In addition, UVB can also cause deep damage to the dermis, including damage to blood vessels, various cells, and collagen fibers, which will aggravate the inflammatory response. Therefore, people with acne and skin damage will recover very slowly after sun exposure. Summary of the invention

[0003] In view of the above technical problems, the present invention provides a skin care composition and a preparation method and application thereof. The skin care composition provided by the present invention can repair skin damage caused by ultraviolet rays, has a significant repair effect, can be added and applied to various types of skin care products, has moderate cost, is simple to prepare, and is suitable for industrial mass production.

[0064] Test Example 1 This test example investigates the effects of the skin care lotions of Examples 6 to 8 and Comparative Examples 1 to 9 on the expression of hydroxyproline (HYP).

[0065] After culturing HFF-1 cells on the plate for 24 h, the original culture medium was carefully aspirated, and the cells were washed 3 times with PBS. Except for the blank well (control group), 100 μL of the skin care liquid of Examples 6 to 8 and Comparative Examples 1 to 9 was added to the remaining wells, with 6 replicate wells in each group. The HYP content was determined according to the instructions of the HYP detection kit.

[0066] The results are as follows Figure 1~Figure 3 As shown, the results show that compared with the control group, the HYP expression levels of HFF-1 cells treated with the skin care lotions of Examples 6 to 8 were all increased, among which the HYP expression level was significantly increased after treatment with the skin care lotion of Example 7. The HYP content of HFF-1 cells treated with the skin care lotions of Comparative Examples 1 to 9 increased to varying degrees, but the increase was not as significant as that of Example 7.

[0067] HYP can promote collagen synthesis and wound healing, and has a certain antioxidant capacity. The above experimental results prove that the skin care lotion of Example 7 can effectively enhance the skin barrier, reduce the damage of external factors to the skin, accelerate the repair of damaged skin, and improve the skin's ability to resist oxidative damage.

[0068] Test Example 2 This test example investigates the effects of the skin care lotions of Example 7 and Comparative Examples 1 to 9 on inflammatory factors.

[0069] HFF-1 cells were inoculated in a 24-well plate, and a control group, a model group, an example 7 group, a comparative example 1 group, a comparative example 2 group, a comparative example 3 group, a comparative example 4 group, a comparative example 5 group, a comparative example 6 group, a comparative example 7 group, a comparative example 8 group and a comparative example 9 group were set up, with 3 replicates in each group. After the cells were cultured until they adhered to the wall and the density was about 80%, 5 μL PBS was added to the control group, and 5 μL unsaturated fatty acid mixture (oleic acid to linoleic acid molar ratio of 1:1) was added to each of the model group, the example 7 group and the comparative examples 1 to 9 groups to significantly increase the level of inflammatory factors in HFF-1 cells. After incubation for 4 h, the original culture medium was discarded, and the control group and the model group were replaced with 1 mL of fresh DMEM culture medium. A mixture of 100 μL of the skin care lotion of Example 7 and 900 μL of fresh DMEM culture medium was added to the Example 7 group, and a mixture of 100 μL of the skin care lotion of Comparative Examples 1 to 9 and 900 μL of fresh DMEM culture medium was added to the Comparative Examples 1 to 9 groups, respectively. The cells were incubated for 48 h, the supernatant was centrifuged, and the inflammatory factor content in the supernatant was detected by ELISA.

[0070] The results are as follows Figure 4 ~ and Figure 6 As shown, compared with the control group, the levels of three inflammatory factors IL-1α, IL-6 and IL-8 in the model group were significantly increased, and after treatment with the skin care lotion of Example 7, compared with the model group, the levels of the three inflammatory factors were significantly decreased, while compared with the model group, the levels of IL-1α, IL-6 and IL-8 in the comparison examples 1 to 9 groups were decreased or unchanged after treatment with the skin care lotion, and the anti-inflammatory effect was obviously not as good as that of Example 7.

[0071] The above results prove that the skin care lotion of Example 7 can reduce skin inflammatory response and skin allergy, thereby helping the skin to repair quickly.

[0072] Test Example 3 This test example investigates the effects of the skin care lotions of Example 7 and Comparative Examples 1 to 9 on sunburn erythema in mice.

[0073] Take 5-6 week old KM mice, remove 2cm×2cm hair on the back of the mice, and randomly divide the mice into a blank group, a model group, an Example 7 group, and a comparative example 1-9 group, with 5 mice in each group. After the mice in the model group, the Example 7 group, and the comparative example 1-9 group were exposed to a 310nm ultraviolet lamp for 48h, erythema and swelling appeared on the back of the mice, and corresponding treatments were performed: the model group (erythema), the Example 7 group (erythema + Example 7), and the comparative example 1-9 group (erythema + comparative example 1-9). The Example 7 group and the comparative example 1-9 group were coated with the corresponding composition or comparative example daily, and the experiment lasted for 20 days. The erythema was observed on the 10th day and the 20th day of coating, and the score was scored according to the degree of skin erythema disappearance, and the average score was calculated to judge the strength of anti-ultraviolet damage.

[0074] Scoring criteria: erythema not subsided, 0 points; 1 point if erythema subsides by 10%; 20% reduction in erythema, 2 points; 30% reduction of erythema, 3 points; 40% reduction of erythema, 4 points; 50% reduction of erythema, 5 points; 60% reduction of erythema, 6 points; erythema subsided by 70%, 7 points; Erythema subsided by 80%, 8 points; 90% reduction of erythema, 9 points; Complete disappearance of erythema, 10 points.

[0075] The experimental results are shown in Table 1.

[0076] Table 1 Average scores

[0077] As can be seen from Table 1, compared with Comparative Examples 1 to 9, the skin care liquid of Example 7 of the present invention had the most obvious reduction in erythema of mice on the 10th day of application, and the erythema was completely reduced after long-term use, indicating that the use of the skin care composition of the present invention has a good redness-reducing effect and is helpful for repairing after UV damage.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
