Technical Field

[0001] This invention relates to the field of skincare technology, specifically to a composition with soothing and repairing effects on sensitive skin, its preparation method, and its application. Background Technology

[0002] Sensitive skin typically has a reduced tolerance to irritants, resulting in a range of abnormal sensory reactions, such as stinging, burning, tightness, and itching. These subjective symptoms are most common on the face. Sensitive skin generally appears normal or may exhibit some flaking, erythema, and dryness.

[0003] Skincare products are widely used and essential for consumers, offering benefits such as moisturizing and hydrating, and improving skin condition. However, for consumers with sensitive skin, many skincare products fail to alleviate sensitivity and may even worsen allergic reactions due to the irritation caused by some of their ingredients. Therefore, consumers with sensitive skin are extremely cautious when choosing skincare products.

[0079]

[0080]

[0081] Efficacy verification:

[0082] The soothing and repairing creams prepared in Examples 1-4 and Comparative Examples 1-9 were used as test products for efficacy testing.

[0083] 1) Test subjects

[0084] Subjects aged 25-55 years who were assessed as having sensitive skin (stinging score ≥3 points) based on a lactic acid stinging test were included. Subjects were then grouped according to the tested product, with 25-35 people in each group.

[0085] 2) How to use

[0086] After cleansing, apply an appropriate amount of the test product evenly to the face and massage until absorbed. Use twice daily, once in the morning and once in the evening. During the testing period, participants should not change their other lifestyle, dietary, or skincare habits, and should use the provided test product entirely instead of their own face cream.

[0087] 3) Testing methods

[0088] Tests were conducted on each subject before using the test product (baseline values) and 28 days after use. The procedure for each test was as follows: subjects cleansed their faces with a designated cleanser sample, then sat quietly for 30 minutes in a laboratory at a temperature of 21±1℃ and humidity of 50±10% RH. Facial imaging data was then acquired using VISIA-CR to obtain the skin redness zone a* value (the smaller the value, the less redness). The transepidermal water loss rate of the cheeks was measured using a Tewameter™ Hex probe (the smaller the value, the less transepidermal water loss per unit time and unit cross-sectional area, indicating a better skin barrier).

[0089] 4) Test Results

[0090] 4.1 The soothing and repairing creams prepared in Examples 1-4 and Comparative Examples 1-9 were used as test samples. The average transepidermal water loss rate of the skin in each group of subjects is shown in Table 3. The reduction rate was calculated according to the following formula:

[0091] Reduction rate (%) = (Test value before use - Test value after use) / Test value before use * 100%

[0092] Table 3

[0093]

[0094] As can be seen from the results in Table 3, the soothing and repairing creams prepared in Examples 1-4 have a very good repairing effect on sensitive skin. Compared with before use, the rate of reduction in transepidermal water loss of the skin after 28 days of use reached more than 20%.

[0095] The results of comparing Example 1 with those of Comparative Examples 1-4 and 9 show that the absence of water / butanediol / Tremella fuciformis polysaccharide, asiaticoside / Centella asiatica extract, lecithin / aescin / β-sitosterol, or water / butanediol / medicago sativifolia extract all resulted in a significantly lower rate of reduction in transepidermal water loss compared to Example 1.

[0096] Further comparison of the results of Example 1 with Comparative Example 5, Example 2 with Comparative Examples 6-7, and Example 3 with Comparative Example 8 shows that changing the weight ratios of water / butanediol / Tremella fuciformis polysaccharide, asiaticoside / Centella asiatica extract, lecithin / aescin / β-sitosterol, and water / butanediol / medicago sativa extract (beyond the range of 0.3-2:0.1-0.6:0.05-0.5:0.05-0.5:0.1-0.3:0.001-0.01) resulted in varying degrees of reduction in the transepidermal water loss rate of the comparative examples compared to the comparative examples.

[0097] Further comparison of the results of Example 1 and Comparative Example 9 shows that when the hydroxyascorbic acid glycoside / Centella asiatica extract was replaced with cyclodextrin / Centella asiatica extract, the rate of reduction in transepidermal water loss from the skin also decreased.

[0098] 4.2 The soothing and repairing creams prepared in Examples 1-4, Comparative Examples 2-4, Comparative Examples 6-7, and Comparative Example 9 were used as test samples. The skin redness a* values ​​measured in each group of subjects are shown in Table 4. The reduction rate was calculated according to the following formula:

[0099] Reduction rate (%) = (Test value before use - Test value after use) / Test value before use * 100%

[0100] Table 4

[0101]

[0102] As can be seen from the results in Table 4, the soothing and repairing creams prepared in Examples 1-4 have a very good effect on soothing sensitive skin. Compared with before use, the a* value of the skin red area decreased by more than 10% after 28 days of use.

[0103] Comparing the results of Example 1 with Comparative Examples 2-4 and 9, it can be seen that the absence of asiaticoside / centella asiatica extract, lecithin / aescin / β-sitosterol or water / butanediol / medicago sativa extract, or the replacement of asiaticoside / centella asiatica extract with cyclodextrin / centella asiatica extract, resulted in a significantly lower reduction rate of a* value in the skin red area compared to Example 1.

[0104] Further comparison of the results of Example 2 with those of Comparative Examples 6-7 shows that changing the weight ratio of lecithin / aescin / β-sitosterol and water / butanediol / medicago sativa extract also resulted in a significantly lower reduction rate of a* value in the skin red area compared to Example 2.

[0105] Among them, the soothing repair cream prepared in Example 4 was used as the test sample, and typical examples of effective improvement in the skin redness area of ​​the subjects are as follows: Figure 1 As shown, by Figure 1 The VISIA-CR images clearly show the changes in the skin redness area of ​​the subjects before and after use.

[0106] In summary, this invention combines raw materials containing specific functional components such as Tremella fuciformis polysaccharide, hydroxyascorbic acid glycoside, Centella asiatica extract, aesculin, alfalfa extract, allantoin, and sodium hyaluronate, and selects a specific weight ratio range so that the components work together to significantly reduce the transepidermal water loss rate and the a* value of the skin red zone in sensitive skin, thus exhibiting excellent soothing and repairing effects.

[0107] This invention has many specific applications, and the above description is only a preferred embodiment. It should be noted that the above embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this invention. For those skilled in the art, several improvements can be made without departing from the principle of this invention, and these improvements should also be considered within the scope of protection of this invention.
