Description

Technical Field

[0001] The present invention relates to the technical field of cosmetics, and in particular to a repairing and anti-aging composition suitable for sensitive skin, and a preparation method and application thereof. Background Art

[0002] With the influence of internal and external factors such as the worsening environmental pollution, the popularization of beauty and skin care products, and the increase in life pressure, sensitive skin problems have become increasingly common, which in turn has driven the market size of sensitive skin care products to continue to expand.

[0003] Compared with normal skin, the barrier function of sensitive skin is relatively weak and it is more sensitive to stimulation from internal and external factors. Even slight negligence, such as wrong ingredients or skin care steps, may aggravate the skin's sensitive reaction and even cause skin inflammation, making the skin's immune system more easily activated and releasing inflammatory factors, leading to dryness, wrinkles, redness and swelling. With repeated inflammation and continuous activation of the immune system, the self-repair ability of sensitive skin may gradually weaken, leading to further weakening of the skin's barrier function, thus triggering a new round of skin inflammation. This vicious cycle will accelerate the aging process of the skin.

[0004] Most products designed for sensitive skin focus on relieving dry skin and reducing inflammation, but they do not fully consider that sensitive skin actually needs a skin care solution that can simultaneously repair the skin barrier function and resist skin aging. Traditional anti-aging products often contain ingredients such as retinol, which are not suitable for the fragile characteristics of sensitive skin and its need for immediate repair. Instead, they may further weaken the skin barrier of sensitive skin and aggravate the sensitive condition. Therefore, it is necessary to develop a skin care solution that can simultaneously repair the skin barrier function and resist skin aging, so as to meet the daily skin care needs of sensitive skin. Summary of the invention

[0005] In order to develop a skin care solution that can simultaneously repair the skin barrier function and resist skin aging, the present application provides a repair and anti-aging composition suitable for sensitive skin, and its preparation method and application. The repair and anti-aging composition suitable for sensitive skin of the present application can accurately combat the skin aging problem caused by skin inflammation while repairing and resisting inflammation, effectively control skin inflammation, strengthen the epidermis, improve skin healing ability, and achieve a good anti-aging effect that is mild and non-irritating.

[0006] In the first aspect, the present application provides a repair and anti-aging composition suitable for sensitive skin, which adopts the following technical scheme: a repair and anti-aging composition suitable for sensitive skin, comprising blue copper peptide, ceramide NP and dipalmitoyl hydroxyproline, wherein the mass ratio of the blue copper peptide, ceramide NP and dipalmitoyl hydroxyproline is (1-5): (2-10): (20-100).

[0007] In the above technical scheme, the present application specifically selects and proportions blue copper peptide, ceramide NP and dipalmitoyl hydroxyproline as a repair and anti-aging composition for sensitive skin, which can accurately combat the problem of skin aging caused by skin inflammation while repairing and anti-inflammatory. Blue copper peptide (GHK-Cu) is a signal peptide that can stimulate fibroblasts to synthesize glycosaminoglycans, proteoglycans, collagen, elastin, etc., to achieve the purpose of reshaping the skin structure. In addition, blue copper peptide can increase the activity of superoxide dismutase by providing copper ions to tissues, thereby inhibiting the generation of reactive oxygen free radicals, achieving antioxidant effects, and can significantly increase the expression of integrins and p63 proteins, enhance the proliferation potential of epidermal stem cells, and promote skin renewal and repair. Inhibit the secretion of inflammatory factors, by regulating the activity of MMPs and TIMPs, help maintain the balance between matrix decomposition and synthesis, accelerate tissue reconstruction, and improve the appearance of skin aging. Ceramide NP maintains the moisture of the skin by constructing a reticular structure in the stratum corneum, significantly enhancing the adhesion between stratum corneum cells, thereby improving the dryness of the skin. Supplementing ceramide NP helps to resist the damage of external stimuli, strengthen the defense ability of the keratinocyte layer, maintain the integrity of the sebum membrane, improve the skin's tolerance, repair red blood streaks, prevent sensitivity, improve skin wrinkles and elasticity in many ways, and effectively delay skin aging. As a natural anti-aging ingredient, dipalmitoyl hydroxyproline can act deeply into the dermis, effectively promote the contraction of collagen fibers, and protect laminin, elastic fibers and fibroblasts from damage. At the same time, dipalmitoyl hydroxyproline can repair the skin's anti-aging defense mechanism by scavenging free radicals, stimulate the production of tissue inhibitors of metalloproteinases (TIMPs), inhibit the activity of matrix metalloproteinases (MMPs), and further improve the elasticity and firmness of the skin.

[0008] The present application found in the study that blue copper peptide, ceramide NP and dipalmitoyl hydroxyproline played a significant synergistic role in repairing the barrier of sensitive skin and improving the anti-aging effect of sensitive skin. Specifically, in terms of repairing the barrier of sensitive skin, the synergistic effect of blue copper peptide, ceramide NP and dipalmitoyl hydroxyproline can significantly soothe sensitive skin, effectively enhance the barrier function of the skin, and enhance the skin's resistance to external stimuli. In terms of improving the anti-aging and whitening effects of sensitive skin, the combination of blue copper peptide and dipalmitoyl hydroxyproline can act on the dermis, enhance the dermis reticular structure, significantly stimulate the production of collagen and improve the firmness of the skin. At the same time, the addition of ceramide NP further enhances the skin's moisturizing and barrier functions. The three work together to make the repair and anti-aging composition of the present application show good repair and anti-aging effects on sensitive skin, and it is mild and non-irritating, suitable for long-term use.

[0009] Preferably, the mass ratio of the blue copper peptide, ceramide NP and dipalmitoyl hydroxyproline is (1-3): (2-5): (20-50).

[0010] In the above technical scheme, the present application further optimizes the mass ratio of blue copper peptide, ceramide NP and dipalmitoyl hydroxyproline, so that the repair and anti-aging composition can exert better synergistic effects when applied to sensitive skin, and can show better repair and anti-aging effects.

[0011] In the second aspect, the application of a repairing and anti-aging composition suitable for sensitive skin in cosmetics provided by the present application adopts the following technical solution: The invention discloses an application of a repairing and anti-aging composition suitable for sensitive skin in cosmetics, wherein the repairing and anti-aging composition suitable for sensitive skin is added into the cosmetics.

[0070] Human efficacy testing A total of 80 subjects were recruited and screened, including 15 males and 55 females aged between 32 and 50 years old. The subjects self-identified as having sensitive, dry, and rough skin, and were confirmed to be sensitive skin people after testing by dermatologists.

[0071] The subjects were divided into 8 groups, 10 people in each group, and the emulsions of Examples 1 to 3 and Comparative Examples 1 to 5 were used respectively. The method of use was to clean the face with the same cleaning product every morning and evening, apply an appropriate amount of the emulsion to the face, massage until completely absorbed, and use it continuously for 14 days. During the entire test period, long-term sun exposure, outdoor sports, travel, etc. were not allowed. During the entire test period, cosmetics or medicines with similar efficacy to the samples were not allowed to be used. During the test period, the subjects were not allowed to change their daily care habits.

[0072] The subjects cleaned their faces with the same cleansing product before use and after 14 days of use, dried their faces with a dandruff-free absorbent face towel, and then sat in a laboratory at 20℃~22℃, 40%~60% RH for 30 minutes to conduct the following tests: Transepidermal Water Loss TEWL value: tested with Tewameter TM Hex, a skin water loss test probe. The smaller the measured value, the lower the skin water loss rate, indicating that the skin barrier function is better. The average value of each group of test results was taken, and the relative change rate (%) after 14 days of use was calculated.

[0073] Red zone area: detected by Antera 3D, a multifunctional 3D skin imaging analyzer. The smaller the red zone area, the less redness of the skin, indicating a better skin soothing and repairing effect. The average value of each group of test results was taken, and the relative change rate (%) after 14 days of use was calculated.

[0074] Skin firmness characterization F4 value: tested using skin multifunctional elasticity test system MPA580. The smaller the measured value, the better the skin firmness. The average value of each test result is taken, and the relative change rate (%) after 14 days of use is calculated.

[0075] Skin wrinkle (SEw) value: tested using the skin texture test system VisioScan VC20 plus. The larger the measured value, the deeper and wider the skin wrinkles. The average value of each test result was taken, and the relative change rate (%) after 14 days of use was calculated.

[0076] Skin sensitivity test: 10% lactic acid solution and distilled water were used for the test. First, a cotton swab soaked in a certain amount of 10% lactic acid solution was applied to the nasolabial groove on one side of the face, and an equal amount of distilled water was applied to the other side; 30s, 2.5min and 5min after application, the facial sensation of the subject was asked and recorded, where 0 points indicated no tingling, 1 point indicated mild tingling, 2 points indicated moderate tingling, and 3 points indicated severe tingling. Each subject recorded the cumulative score of tingling. The smaller the cumulative score of pain, the lower the skin sensitivity. The average of each group of test results was taken, and the relative change rate (%) after 14 days of use was calculated.

[0077] Relative change rate after 14 days of use (%) = (average value before use - average value after use) / average value before use * 100%.

[0078] The above test results are shown in Table 2.

[0079] Table 2: Specifically combined with the test data analysis of Examples 1 to 3 and Comparative Examples 1 to 5, it can be seen that after continuous use of the emulsions of Examples 1 to 3 for 14 days, the skin water loss rate of the subjects was significantly reduced, the skin barrier function was effectively enhanced, and the red zone area was significantly reduced, indicating that the skin redness was significantly improved, the soothing and repairing effect was significant, and the skin firmness characterization F4 value became smaller, indicating that the skin firmness was improved, and the wrinkle depth (SEw value) was also reduced, showing a good anti-aging effect, and the significant reduction in the cumulative pain score also showed that the skin tolerance was improved. It can be seen that the emulsion containing the composition of dipalmitoyl hydroxyproline, ceramide NP and blue copper peptide performs well in improving the barrier function of sensitive skin and enhancing the anti-aging effect.

[0080] Specifically combining the analysis of the emulsions of Example 1 and Comparative Examples 1 to 5, it can be seen that the emulsions of Comparative Examples 1 to 5 did not use dipalmitoyl hydroxyproline, ceramide NP and blue copper peptide, respectively, that is, Comparative Examples 1 to 5 did not use the repair and anti-aging composition suitable for sensitive skin. Example 1 showed good effects in improving skin moisture loss, red zone area, skin firmness, wrinkle depth and skin tolerance. It can be seen that the repair and anti-aging composition of the present application significantly improves the barrier function and anti-aging effect of sensitive skin through the three active ingredients of dipalmitoyl hydroxyproline, ceramide NP and blue copper peptide, and is mild and non-irritating, providing an effective repair and anti-aging solution for sensitive skin.

[0081] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
