Description

Technical Field

[0001] The invention belongs to the technical field of skin care products and relates to an essence with repairing and moisturizing functions and a preparation method thereof. Background Art

[0002] Repair essence is a high-end product in skin care products, which is popular for its highly concentrated active ingredients and targeted repair effects. In recent years, with the improvement of consumers' awareness of skin health and skin care, the market demand for repair products has increased significantly. With the upgrading of demand and the iteration of technology, the repair effect market has shown more new possibilities, and major subcategories also have the potential for further development. Repair essence products are constantly improving in technology, especially in the research and application of active ingredients. Special products for different skin problems (such as sensitive skin, acne skin, damaged barrier, etc.) have appeared on the market, reflecting the segmentation and specialization of technology. Although the market demand for repair essence has increased, the product homogeneity is serious and lacks innovation. There are many types of essences on the market, but the following problems are common: Limited moisturizing effect: Many moisturizing essences contain only a single moisturizing ingredient, such as glycerin or hyaluronic acid. Although these ingredients can temporarily replenish skin moisture, the moisturizing effect lasts for a short time and cannot meet the needs of long-term moisturizing; Insufficient repair function: The skin is easily damaged by the external environment in daily life, such as ultraviolet rays, pollution, etc. These factors can cause damage to the skin barrier and cause redness, swelling, sensitivity and other problems. Existing moisturizing essences often lack effective repair ingredients and cannot solve the moisturizing and repair problems at the same time; Complex formula: In order to pursue better results, some moisturizing essences add a large number of ingredients, resulting in complex formulas, high costs, and may cause skin allergies and other problems; The product's use effect and safety are poor.

[0033] Moisturizing performance test Skin water loss reduction test: The transepidermal water loss (TEWL value) is an important indicator for evaluating the strength of skin barrier function. The TEWL value is measured by a transepidermal water loss tester.

[0034] The test samples are Examples 1-5 and Comparative Examples 1-7.

[0035] Experimental plan: 25±5 years old subjects with dry skin were selected, and a total of 12 experimental groups were set up, with three people in each group. A 4×4cm test area was marked on the outside of each subject's arm. Two areas can be marked on the same arm, with an interval of 1cm. The test samples and blank controls were randomly distributed on the left and right arms.

[0036] The test area and the control area were measured using a capacitive skin analyzer. Each area was measured 15 times in parallel. The blank value of each test area was measured first, and then 1g of test sample / 4×4cm was evenly applied to the test area. The skin moisture content of the test area and the blank control area was measured 1, 2, and 4 hours after application (measured at this time during verification).

[0037] Evaluation criteria: According to the experimental design, the TEWL values ​​of each time period were measured, and the reduction in skin water loss at each time point was calculated (average value for each group). The greater the reduction in skin water loss, the better the effect of skin barrier repair.

[0038] Calculation formula: Reduction in skin water loss = [(T0-T1) / T0] × 100% T1 is the TEWL value of the test group at each time point, and T0 is the TEWL value of the blank control group at each time point. The results are shown in Table 1.

[0039] Result analysis: When the test time is 4h, the rate of change of the reduction of skin moisture loss in Examples 1-5 is faster than that in Comparative Examples 1-7, indicating that the compositions of Examples 1-5 have less moisture loss during long-term moisturizing and are more conducive to long-term moisturizing.

[0040] Repair performance test Testing method: 30 subjects were selected, and the results of the lactic acid stinging test showed that the skin was moderately to severely sensitive; the age range was 20-30; a before-and-after control method was used, and the hemoglobin content of the skin on the cheeks of the subjects was tested after using the product of Example 2 for 60 minutes (one pump of essence is about 0.4-0.6 ml for a 4×4 cm skin area), using the product for one day, and using the product for four days. The measuring instrument was the skin melanin and hemoglobin tester ProbeMex ameterMX18 (CK, Germany).

[0041] The test principle is based on spectral absorption. The hemoglobin content in the skin is determined by measuring the amount of reflection of light of a specific wavelength (the instrument will directly display the result value after use) (568nm, 660nm, 880nm) on human skin. The transmitter of the instrument probe emits three wavelengths of light on the skin surface, and the receiver measures the light reflected by the skin. Since the amount of emitted light is certain, the amount of light absorbed by the skin can be measured, thereby measuring the hemoglobin content in the skin. The test results are shown in Table 2-3.

[0042] Among them, the measured value, the hemoglobin content value decreased, indicating that the product can soothe the skin.

[0043] Improvement rate = [(average hemoglobin value before use - average value after using the product) / average hemoglobin value before use] × 100%.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
