Description

Technical Field

[0001] This invention belongs to the field of cosmetic technology, specifically relating to a composition with skin-firming and brightening effects and its application. Background Technology

[0002] Skin laxity is a typical skin problem caused by skin aging and external environmental stimuli. Its core pathophysiological mechanism lies in the reduced synthesis, structural disorder, or accelerated degradation of collagen and elastin fibers in the dermis. Simultaneously, the supporting force of subcutaneous fat tissue and muscles weakens, leading to decreased skin elasticity and reduced anti-gravity capacity, resulting in wrinkles, sagging, and other morphological changes. Aging, excessive UV exposure, mental stress, and poor lifestyle habits are all internal and external factors that can induce oxidative stress in the skin, stimulating increased activity of matrix metalloproteinases, accelerating the destruction of the fiber network, and inhibiting the synthesis of collagen and elastin by fibroblasts, thus exacerbating the skin laxity process. With consumers' evolving skincare awareness and growing demand for anti-aging products, firming cosmetics have become a core category in the functional skincare field, and the market's requirements for their efficacy, safety, and stability are becoming increasingly stringent.

[0003] CN120392575A discloses a method for preparing a polypeptide composition with anti-wrinkle and firming effects, belonging to the field of cosmetic raw material preparation technology. The method includes the following steps: S1, raw material pretreatment; S2, raw material mixing; S3, pH adjustment: adjusting the pH of the polypeptide mixture solution to 5.5-6.5 using hydrogen phosphate or citric acid solution; S4, filtration sterilization: filtering the pH-adjusted polypeptide mixture solution through a 0.22μm microporous membrane to obtain a sterile polypeptide composition solution; S5, filling: filling the sterile polypeptide composition solution into suitable packaging containers. This invention achieves anti-wrinkle and firming effects through the synergistic combination of five polypeptides, including palmitoyl pentapeptide-3 and acetyl hexapeptide-8, via a four-pronged mechanism: stimulating collagen regeneration, inhibiting nerve signals, blocking protease degradation, and anti-oxidation.

[0004] CN120983321A discloses an anti-wrinkle and firming composition and its uses, as well as cosmetics, comprising oregano leaf extract and tribulus fruit extract, wherein the mass ratio of oregano leaf extract to tribulus fruit extract is 1-10:5-15. This application demonstrates that the synergistic effect between oregano leaf extract and tribulus fruit extract can effectively provide good anti-wrinkle and firming effects on the skin in terms of free radical scavenging and elastase inhibition. Furthermore, the anti-wrinkle and firming ability of the composition is further enhanced by adding yarrow extract.

[0005] However, existing technologies for firming cosmetics mainly focus on optimizing the addition and delivery systems of active ingredients. Mainstream active ingredients include peptides and plant extracts, but these products generally suffer from low transdermal absorption efficiency, poor formula stability, and insufficient synergistic effects, failing to fully meet consumers' core needs for gentle, long-lasting, and safe firming skincare. Therefore, developing a cosmetic that can improve the absorption efficiency of active ingredients, achieve multi-target synergistic firming, and balance formula stability and safety has become a pressing technical challenge for those skilled in the art. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the present invention provides a composition with skin-firming and brightening effects and its application.

[0007] To achieve this objective, the present invention adopts the following technical solution: In a first aspect, the present invention provides a composition having skin-firming and brightening effects, the composition comprising collagen, acetyl hexapeptide-8, olive fruit oil, meadowfoam seed oil and rose oil.

[0008] The collagen in the composition of this invention can directly replenish the collagen matrix lost by the skin, increase skin elasticity and firmness, improve skin roughness, and its molecular structure can lock in moisture, improve dry and dull skin, and lay the foundation for brightening the skin. The acetyl hexapeptide-8 can inhibit nerve signal transmission and relax muscles that cause wrinkles. The olive fruit oil is rich in nutrients such as squalene and fatty acids, which have the effects of rapid nourishment, moisturizing and anti-oxidation. The meadowfoam seed oil is rich in high-purity long-chain fatty acids with extremely strong oxidative stability, which can indirectly protect collagen through anti-oxidation, prevent wrinkles, and brighten skin tone. The rose oil is rich in vitamin A, vitamin C, fatty acids, etc., which can improve uneven skin tone and dullness, lighten fine lines and scars, and make the skin tone more even and radiant. This invention creatively discovers that the above five components work together synergistically to significantly increase the moisture content of the stratum corneum, improve skin luster and elasticity, and achieve excellent firming and brightening effects.

[0009] Preferably, the composition comprises, by weight, 0.01-1 parts collagen, 1-5 parts acetyl hexapeptide-8, 5-25 parts olive fruit oil, 5-25 parts meadowfoam seed oil, and 0.1-1 parts rose oil.

[0016] In this invention, recombinant human type III collagen can easily penetrate the stratum corneum to reach the superficial dermis. It can be efficiently absorbed by the skin without the need for complex delivery carriers. After absorption, it can quickly replenish the lost type III collagen in the skin, improve skin elasticity and plumpness, and improve fine lines and sagging. Recombinant human type IV collagen can maintain the integrity of the skin barrier, reduce external stimuli and free radical invasion, inhibit melanin transfer to the epidermis, and help brighten skin tone. Recombinant human type XVII collagen is easily recognized and absorbed by the stratum corneum cells. After absorption, it can stabilize epidermal stem cells, promote the normal metabolism and renewal of stratum corneum cells, improve skin roughness and dullness, and improve skin tone translucency. At the same time, it works synergistically with type III and type IV collagen to strengthen the skin structure support, reduce wrinkle formation, and thus help the composition achieve simultaneous improvement in firmness and brightening.

[0064] Test Example 1: Evaluation of Firming Effect Test samples: Eye firming serums provided in Application Examples 1-12 and Comparative Examples 1-6.

[0065] Test Method: 126 healthy Chinese women aged 25-40 years with dry, rough, and loose skin, dark circles, and eye bags were selected and divided into 18 groups of 7 participants each. Each group was tested with a different sample. The test product was applied to the entire face once nightly. Skin elasticity and firmness were measured weekly using a Cutometer MPA580, the area of ​​crow's feet was measured using a VISIA 7 facial imaging device, and the depth of crow's feet was measured using an EvaFACE rapid optical imaging system. The test ended after 4 weeks (28 days), and the results are shown in Table 1.

[0066] Table 1 As shown in Table 1, compared with Comparative Application Example 6, the eye firming essence of the present invention, by adding a composition with firming and brightening effects, can significantly reduce wrinkles around the eyes, improve skin elasticity, and achieve a noticeable skin firming effect.

[0067] As can be seen from Application Examples 4-5, the ratio of olive fruit oil to meadowfoam seed oil affects the firming effect of the product. Only when the ratio is within the range defined by this invention can the firming effect be better. As can be seen from Application Examples 6-8, collagen can only improve the firming effect of the product when it is in the combination specified in this invention, and recombinant human type III collagen, recombinant human type IV collagen and recombinant human type XVII collagen have a synergistic effect on firming. As can be seen from Application Examples 9-12, the firming effect of the product is more significant when a skin conditioning agent is added to the product, and the skin conditioning agent is a specific combination of the present invention. As can be seen from the comparative application examples 1-5, the five components of collagen, acetyl hexapeptide-8, olive fruit oil, meadowfoam seed oil and rose oil have a synergistic effect on firming. All five are indispensable, and the absence of any one component will reduce the performance of the product.

[0068] Test Example 2: Skin Feel Evaluation After completing Test Example 1, volunteers rated their experience using a 5-point scale: 4.5 points and above indicated excellent and very satisfied; 4-4.5 points indicated good; 3-4 points indicated moderately acceptable; and below 3 points indicated poor and unacceptable. The scores for each group were the average of the 6 participants, and the results are shown in Table 2.

[0069] Table 2 As shown in Table 2, compared with Comparative Application Example 6, the volunteers had a better experience with the products prepared in Application Examples 1-3, indicating that the composition provided by the present invention has a firming and brightening effect, and the product is gentle and non-irritating after use.

[0070] As can be seen from the comparison of the products in Application Examples 1-5, the five components of the composition of the present invention—collagen, acetyl hexapeptide-8, olive fruit oil, meadowfoam seed oil, and rose oil—are all indispensable; the absence of any one component will reduce the performance of the product.

[0071] Test Example 3: Safety Evaluation Experiment Safety assessment: The specific method was as follows: Forty volunteers aged 20-35 years (half male and half female) with no history of allergies were selected. Each subject used the samples prepared in Examples 1-3. After cleaning the subject's arm, the patch applicator containing the sample was applied to the selected location on the arm using non-irritating adhesive tape. After application, the patch was gently pressed with the fingers to ensure even application to the skin, and left for 24 hours. During these 24 hours, the subject kept the patch area dry and avoided strenuous exercise, scratching, and prolonged sun exposure. After 24 hours, the applicator was removed and marked. After 30 minutes, once the pressure marks disappeared, the applicator was evaluated under sufficient light.

[0072] The grading criteria for adverse skin reactions are shown in Table 3: Table 3 The results are shown in Table 4: Table 4 As shown in Table 4, all subjects had negative reactions, indicating that the product prepared according to the present invention has no adverse reactions on the human body and is highly safe.
