Description

Technical Field

[0001] The invention belongs to the field of skin care functional products, and specifically relates to a soothing and moisturizing composition, a facial mask and a preparation method thereof. Background Art

[0002] In the field of skin care, moisturizing and soothing are the two issues that consumers are most concerned about. Although traditional skin care products meet the need for moisturizing to a certain extent, they are still insufficient in soothing the skin and reducing external stimuli. The skin is a natural barrier between the body and the environment. By maintaining an effective epidermal barrier to protect the body from environmental influences, it can not only resist external factors, but also prevent the body from losing water. The hydration level not only affects the visible skin state, such as the softness of the skin, but also affects the cell metabolism, enzyme activity and signal transduction in the epidermis. Therefore, sufficient skin hydration is essential to maintaining skin health, and moisturizing is an important part of basic skin care.

[0003] The water content of the normal stratum corneum is 20%-35%. When the water content of the stratum corneum drops below 10%, the skin barrier function will be damaged and secondary problems such as skin allergies, irritation and inflammation will be caused. Therefore, developing a product that can provide both moisturizing and soothing effects is of great significance to meet the skin care needs of modern consumers.

[0004] In terms of moisturizing technology, although traditional moisturizing ingredients such as glycerin and butylene glycol have certain moisturizing effects, they often fail to meet the needs of modern consumers for deep skin moisturizing. In addition, although some new moisturizers such as hyaluronic acid and seaweed extracts can provide better moisturizing effects, the use of a single ingredient often has problems such as poor permeability and short-lasting moisturizing effects. Therefore, it is necessary to develop a composition composed of multiple natural plant extracts and high-efficiency moisturizers, and form a skin care system with high permeability and long-lasting moisturizing through scientific proportioning.

[0005] In terms of soothing technology, skin sensitivity, redness and swelling have become common skin problems for modern consumers. Although traditional soothing methods such as cold compresses and ointments can temporarily relieve skin discomfort, the long-term effect is not ideal. Therefore, it is necessary to develop a composition with soothing effect, which can effectively soothe the skin and reduce the damage to the skin caused by external stimuli through the active ingredients in natural plant extracts. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a composition consisting of a variety of natural plant extracts and a high-efficiency moisturizer, and to prepare a composition and a product thereof with dual moisturizing and soothing effects through scientific proportioning and preparation methods.

[0114] Skin water loss reduction test:

[0115] The level of transepidermal water loss (TEWL value) is an important indicator for evaluating the strength of skin barrier function.

[0116] The TEWL value is measured by a transepidermal water loss tester.

[0117] The impregnation solutions 1-3 prepared above were used as test samples.

[0118] Fifteen subjects aged 20-40 with dry skin were selected and divided into three groups. Each test sample was repeated 5 times and the average value was taken. A 3×3 cm mark was made on the inner side of the forearms of both hands of the subjects. 2 Test area: Multiple areas can be marked on the same arm, with an interval of 1 cm. Test samples and blank controls are randomly distributed on the left and right arms. Capacitive skin analyzer is used to measure the test area and control area. Each area is measured 15 times in parallel, first measuring the blank value of each test area, and then measuring the blank value of each test area at 0.5g / 9cm 2The amount is evenly applied in the test area. The skin moisture content of the test area and the blank control area is measured 1, 2, 4, and 8 hours after application (measured at this time during verification). No products (cosmetics or topical medicines) can be used on the test area 2-3 days before. The test environment temperature is controlled at 25±1℃, and the relative humidity is 40±5%. Before the test, the arms of the subjects are wiped with pure water at about 36℃, and the subjects are asked to sit quietly in the test environment for 30 minutes before the test. According to the experimental design, the TEWL values ​​of each time period are measured separately, and the reduction in skin moisture loss at each time point is calculated. The greater the reduction in skin moisture loss, the better the effect of skin barrier repair. The results are shown in Table 8.

[0119] Calculation formula:

[0120] Reduction in skin water loss = [(T0-T1) / T0] x 100%

[0121] Where: T1 is the TEWL corresponding to the test group at each time point, and T0 is the TEWL corresponding to the blank control group at each time point.

[0124] Lactic acid sting evaluation:

[0125] 1. Test principle: Research shows that the occurrence of skin sensitivity is a complex process involving skin barrier, skin nervous system, and skin immune cells. Under the combined effects of internal and external factors, the skin barrier function is damaged, causing an increase in sensory nerve afferent signals, leading to an enhanced skin response to external stimuli and triggering skin immune inflammatory reactions. The score of the lactic acid sting test before and after using the product can directly reflect the product's repairing effect on the skin barrier function.

[0126] The present invention tests the skin barrier repairing effect of the soothing and moisturizing facial mask by evaluating the lactic acid stinging before and after using the product.

[0127] 2. Test Method

[0128] Test environment: The test environment temperature is 22±1℃, the humidity is 50±5%, and real-time dynamic detection is performed;

[0129] Test volunteers: aged between 35 and 45 years old (excluding pregnant or lactating women), a total of 15 people, 5 people in each group; no serious systemic diseases, no immunodeficiency or autoimmune diseases; no history of severe allergies to skin care cosmetics; no use of hormone drugs and immunosuppressants in the past month; no participation in other clinical trials; use of test drugs as required and complete information; all volunteers should fill out an informed consent form before the test.

[0130] Test steps:

[0131] Preparation before the test: Do not use any products (cosmetics or topical medications) on the test area 2-3 days before.

[0132] Test process: The subjects sit quietly in a constant temperature and humidity room for 30 minutes, then use equal amounts of 10% lactic acid aqueous solution and distilled water on the left and right nasolabial grooves of the subjects, and ask the subjects about their skin sensation symptoms at 0.5, 2, and 5 minutes, and score them according to a four-point scale: no tingling sensation is 0 points, mild tingling sensation is 1 point, moderate tingling sensation is 2 points, and severe tingling sensation is 3 points. The test of the same volunteer is completed by the same measurement personnel.
