Description

Technical Field

[0001] The invention belongs to the technical field of cosmetics, and particularly relates to a composition for soothing and relieving redness and inflammatory pigmentation, as well as a preparation method and application thereof. Background Art

[0002] Damage to the skin barrier can cause dryness and itching of the skin, making it more sensitive to external stimuli, making the skin more prone to stress reactions, and causing discomfort such as redness, swelling, itching, pain, and heat. After acute or chronic inflammation of the skin, skin pigmentation often occurs, that is, post-inflammatory pigmentation. This condition usually has no racial or gender differences and is more likely to occur in people with darker skin. The depth and duration vary from person to person. Generally, inflammation and post-inflammatory pigmentation may last for several weeks, or even take 3 to 6 months to gradually subside, which seriously affects the appearance and psychological state of consumers.

[0003] Skin inflammation involves the action of multiple cells and inflammatory factors, and inflammatory pigmentation is first caused by the epidermal inflammatory response, which leads to increased secretion of arachidonic acid, which is oxidized into prostaglandins and lipid compounds, thereby activating the increased synthesis of melanosomes. When the inflammatory response destroys the basal layer of the epidermis, melanin particles are released into the papillary dermis and are engulfed by macrophages in the dermis, resulting in pigmentation; secondly, skin inflammation or trauma destroys the sulfhydryl groups of the skin, weakening its ability to bind copper ions, increasing the activity of tyrosinase, and leading to increased melanin synthesis; in addition, skin inflammation destroys the skin barrier, weakening its ability to resist adverse external stimuli, which can also lead to pigmentation.

[0004] At present, the products on the market often have single effects. Some products only consider relieving discomfort during inflammation by inhibiting inflammatory factors, but the inhibitory effect on melanin synthesis caused by increased tyrosinase activity is not obvious; some products use whitening ingredients to dilute the melanin that has already formed. The use of some conventional whitening ingredients such as VC ethyl ether can prevent melanin synthesis and reduce melanin precipitation, but consumers with damaged or sensitive skin have poor skin conditions, and conventional whitening ingredients are more irritating and may cause more serious skin problems.

[0091] Product performance testing

[0092] Experimental Example 1 Whitening Efficacy Test

[0093] 1.1 Experimental Principle

[0094] There are many factors that affect melanin synthesis. It is more appropriate and scientific to use the change of melanin content in melanocytes to judge the whitening effect of raw materials. At the same time, the synthesis of melanin is mainly regulated by tyrosinase, which is the rate-limiting enzyme for the initial reaction of melanin synthesis in the body. Therefore, this project compares the lightening effect of the combination on pigmentation by exploring the inhibition of melanin production and tyrosinase activity in vitro by single ingredients and combinations.

[0095] 1.2 Experimental methods

[0096] The melanin content after A375 cell lysis was detected by an ELISA instrument to evaluate the inhibitory effect of melanin production, and the tyrosinase activity inhibition effect was evaluated by the mushroom tyrosinase DOPA rate oxidation method, and the whitening effect of the raw materials was comprehensively evaluated.

[0097] Examples 1 to 7 and Comparative Examples 1 to 14 were tested, and the monomer components in Example 1 were used as a control reference. The concentrations of the monomers and the composition in the experiment were both 5 μM.

[0098] 1.3 Experimental Results

[0099] The results are shown in Table 2.

[0100] Table 2 Whitening effect comparison (unit: %)

[0101]

[0102]

[0103] The data in Table 2 above show that resorcinol derivatives, Glycyrrhiza inflata extract, Artemisia annua extract and its derivatives all have relatively significant whitening effects, while zinc salts and proteins have almost no whitening effects. The data of the comparative examples show that not only Glycyrrhiza inflata extract or Artemisia annua extract and its derivatives have good whitening synergistic effects with resorcinol derivatives, but zinc salts and proteins can also enhance the whitening effects of resorcinol derivatives and Glycyrrhiza inflata extract or Artemisia annua extract and its derivatives to a certain extent. The data of the embodiments show that the combination of Glycyrrhiza inflata extract and / or Artemisia annua extract and its derivatives with resorcinol derivatives, zinc salts and proteins has significant whitening effects.

[0104] Experimental Example 2 Anti-inflammatory Efficacy Test

[0105] 2.1 Experimental Principle

[0106] In the inflammatory site, NO is a highly active signaling molecule that plays an important role in regulating cell function. However, long-term, excessive NO can cause cell and tissue damage through cytotoxic effects, and then participate in the occurrence and development of certain inflammatory diseases. Therefore, inhibiting the excessive expression of NO has become an important indicator for the detection of efficacy substances that prevent inflammatory reactions and diseases.

[0107] 2.2 Experimental methods

[0108] The anti-inflammatory efficacy of cosmetic raw materials and finished products was evaluated by measuring the cytotoxicity of cosmetics on RAW264.7 mouse mononuclear macrophage leukemia cells and the inhibitory effect on the pro-inflammatory mediator NO released by them.

[0109] The compositions of Examples 1 to 7 and Comparative Examples 1 to 14 were tested, and the monomer components in Example 1 were used as references, 1 μg / mL LPS (lipopolysaccharide) was used as a control group, and the mass concentrations of the remaining monomers and compositions in the experiment were all 0.01%.

[0110] 2.3 Experimental Results

[0111] The results are shown in Table 3.

[0112] Table 3 NO content (unit: μM)

[0113]

[0114]

[0115] The data in Table 3 above show that protein, Glycyrrhiza inflata extract, Artemisia annua extract and its derivatives all have good anti-inflammatory effects, zinc salts also have certain anti-inflammatory effects, but resorcinol derivatives have no anti-inflammatory effects, and even have a slight pro-inflammatory effect. The data of the comparative examples show that zinc salts, proteins and Glycyrrhiza inflata extract or Artemisia annua extract and their derivatives have good anti-inflammatory synergistic effects, which can better enhance the anti-inflammatory effect. The data of the embodiments show that the composition of the present invention has a significant anti-inflammatory effect.

[0116] Experimental Example 3: Soothing and Removing Redness Test

[0117] 3.1 Experimental Principle

[0118] When sensitive skin is stimulated by physical, chemical, mental and other factors, the skin is prone to subjective symptoms such as burning, stinging, itching and tightness, with or without objective signs such as erythema, scaling, capillary dilation, etc. If it can relieve and improve skin irritation and other conditions, it can be considered to have a soothing effect.

[0119] 3.2 Experimental methods

[0120] 35 subjects with sensitive skin were selected and randomly tested on half of their face. The samples were used once every night. Under the conditions of temperature 20±2°C and humidity 50±10%, after the subjects' faces were cleaned for 20 minutes, lactic acid stinging test questionnaires were conducted on D7 (Day 7) and D14 (Day 14). Antera 3D was used to take photos on D7 and D28 (Day 28) to measure the average value of the facial redness area, and the soothing and redness-reducing effects of the creams of Application Examples 1 to 7 and the creams prepared based on the comparative examples with better in vitro anti-inflammatory data (Application Comparative Examples 3 and 13) on the skin were determined.

[0121] The lactic acid sting test questionnaire is scored on a 4-point scale, with 0 for no sensation, 1 for mild sensation, 2 for moderate sensation, and 3 for severe sensation. Intermediate scores can be used to describe the degree of sensation, such as 0.2, 0.5, 0.7 or other intermediate scores.

[0122] 3.3 Experimental Results

[0123] The results are shown in Tables 4 and 5.

[0124] Table 4 Mean values ​​of lactic acid stinging scores

[0125] Sample set D0 D7 D14 Application Example 1 3.6 2.7 1.9 Application Example 2 3.5 2.4 1.3 Application Example 3 3.8 2.2 1.0 Application Example 4 3.7 2.9 2.1 Application Example 5 3.6 2.6 1.8 Application Example 6 3.5 1.8 0.7 Application Example 7 3.6 2.8 2.0 Application Comparative Example 3 3.5 3.2 2.5 Application Comparative Example 13 3.6 3.0 2.7 Blank group (cream base) 3.7 3.5 3.0

[0126] The data in Table 4 above show that the extract of Glycyrrhiza inflata, the extract of Artemisia annua and its derivatives have a good effect on relieving short-term stinging pain, especially at D7, the relieving effect is obvious; while the protein has a more prominent effect on long-term (D14) soothing, which may be related to the fact that proteins promote epidermal barrier repair. The data of the application examples show that the composition of the present invention has a significant relieving effect, which is better than the comparative example and the blank example.

[0128]

[0129]

[0130] The data in Table 5 above show that the combination of Glycyrrhiza inflata extract or Artemisia annua extract and its derivatives with zinc salt has a better effect on redness reduction, especially at D7, the relief effect is obvious; and the effect of protein on long-term (D28) redness reduction is more prominent, which may be related to the fact that proteins promote epidermal barrier repair. The application example data show that the composition of the present invention has a significant redness reduction effect, which is better than the comparative example and the blank example.

[0131] Experimental Example 4: Acne Scar Reduction Test

[0132] 4.1 Experimental Principle

[0133] Although acne can be relieved by drugs or physical therapy, and the pustules and skin lesions can be relieved and subsided, even if the acne subsides, black and red acne marks, sunken acne pits or hyperplastic convex scars will still be left on the affected area. In order to investigate the effect of the composition of the present invention on the redness and swelling of acne and the reduction of acne marks, a clinical evaluation was conducted on consumers who are in the acne stage and have acne marks before and after using the product.

[0134] 4.2 Experimental methods

[0135] 30 subjects with sensitive skin with obvious acne and acne marks on their faces were selected and randomly divided into three groups. The subjects used the product once in the morning and evening. Before and 7 days after use, at a temperature of 20±2°C and a humidity of 50±10%, the subjects cleaned their faces and waited for 20 minutes. The efficacy of the composition of the present invention in anti-inflammatory acne removal and fading acne marks was comprehensively evaluated by questionnaire and taking photos with a VISIA instrument. The samples selected were application examples 1, 3, and 6 with better verification effects as described above.

[0136] 4.3 Experimental Results

[0137] The results of the questionnaire are shown in Tables 6, 7 and 8, where the effective rate is the sum of significant and very significant;

[0138] VISIA instrument test results are as follows Figure 1 and Figure 2 As shown, Figure 1 This is a comparison chart of the VISIA test of Application Example 3 before use (D0) and 7 days after use (D7). Figure 2 This is a comparison chart of the VISIA tests of Application Example 6 before use (D0) and 7 days after use (D7).

[0145] From the data in Tables 6 to 8 and Figure 1-2 It can be seen that, compared with before use on D7, the improvement of acne marks by application example 3 is the most significant, the improvement of acne in the red, swollen and inflamed state by application example 6 is the most significant, and the effect of fading acne and acne marks by application example 1 is good. The data of the application examples show that the composition of the present invention has a significant effect of soothing, reducing redness and fading pigmentation.

[0146] Based on the test results of the above experimental examples, it can be seen that the present invention rationally mixes Artemisia annua extract and its derivatives and / or Glycyrrhiza inflata extract, zinc salt, resorcinol derivatives and protein, which can not only relieve the redness and swelling during inflammation, promote the repair of damaged skin, but also reduce the color after inflammation and inhibit scar formation.
