Description

Technical Field

[0001] This invention relates to the field of skincare products, and in particular to a plant extract complex with firming and anti-wrinkle effects, its preparation method, and its application. Background Technology

[0002] With social development, people are paying more and more attention to skin health. Among them, wrinkles are one of the most concerning skin problems. Therefore, skin care products with anti-wrinkle effects are among the most popular products.

[0003] Wrinkles are mainly caused by the loss of collagen, the breakage of elastin fibers, and the loss of skin moisture. Existing skincare products primarily work by adding antioxidants to reduce the attack of free radicals on the skin, thereby reducing skin aging and restoring skin vitality to some extent. This accelerates collagen production to resist collagen loss. Some skincare products also contain ingredients that inhibit the activity of elastase, promoting the repair of elastin fibers. Combined with moisturizing ingredients to replenish skin moisture, they achieve a certain degree of anti-wrinkle effect.

[0004] However, existing anti-wrinkle skincare products mainly focus on antioxidant and elastase-inhibiting effects, neglecting the fact that dry skin can also cause serious damage, leading to wrinkle formation. Although existing skincare products contain moisturizing ingredients, these ingredients primarily replenish skin moisture by absorbing moisture from the air. In daily activities, skincare products on the skin's surface are easily worn away. In a fast-paced life, people find it difficult to replenish the worn-out skincare products through frequent use, causing the moisturizing effect to be lost imperceptibly. People usually only remember to reapply skincare products after experiencing significant dryness, leading to a continuous cycle of damage, repair, and further damage to the skin. As a result, the anti-wrinkle effect of skincare products is not obvious and fails to meet consumer needs, thus leaving room for improvement. Summary of the Invention

[0005] To enhance anti-wrinkle efficacy, this application provides a plant extract complex with firming and anti-wrinkle effects, its preparation method, and its application.

[0006] In a first aspect, this application provides a plant extract complex with firming and anti-wrinkle effects, employing the following technical solution:

[0007] A plant extract complex with firming and anti-wrinkle effects comprises the following components in parts by weight:

[0008] Solvent: 84.8-89.2 parts;

[0009] Preservative: 0.8-1.2 parts;

[0010] 10-14 parts of moisturizing and anti-aging composition;

[0011] The moisturizing and anti-aging composition is a blend of extracts of *Chlorella vulgaris*, *Buddleja officinalis*, *Bletilla striata* bulb extract, *Edelweiss*, *Ganoderma lucidum*, and ginseng.

[0012] By adopting the above technical solution, and using a moisturizing and anti-aging composition formulated with extracts of *Chlorella vulgaris*, *Buddleja officinalis*, *Bletilla striata* bulb extract, *Edelweiss*, *Ganoderma lucidum*, and ginseng, this composition can significantly scavenge free radicals, effectively inhibit elastase, and promote skin barrier repair. This prevents skin moisture loss, reduces dependence on moisturizers, and ensures that even after skincare products are worn out, skin moisture is less likely to be lost or become dry. This significantly enhances the anti-wrinkle effect, achieving wrinkle smoothing more quickly and effectively meeting consumer needs.

[0013] Preferably, in the moisturizing and anti-aging composition, the mass ratio of *Chlorella vulgaris* extract, *Buddleja officinalis* extract, *Bletilla striata* bulb extract, *Edelweiss* extract, *Ganoderma lucidum* extract, and ginseng extract is 4-6:0.8-1.2:0.8-1.2:0.8-1.2:1.8-2.2:1.8-2.2.

[0014] By adopting the above technical solution and specifically selecting the mass ratio of extracts such as *Chlorella vulgaris*, *Buddleja officinalis*, *Bletilla striata*, *Edelweiss*, *Ganoderma lucidum*, and ginseng, the active ingredients are better combined in a specific ratio, resulting in better synergistic effects and more significant anti-wrinkle effects.

[0015] Preferably, the solvent is a mixture of water and butanediol in a mass ratio of 73.8-80.2:9-11.

[0016] By adopting the above technical solution and using water and butylene glycol, the solubility of each component in the solvent is high, which can better exert synergistic effects and achieve better anti-wrinkle effect.

[0017] Preferably, the preservative is a compound of 1,2-hexanediol and p-hydroxyacetophenone in a mass ratio of 0.4-0.6:0.4-0.6.

[0018] By adopting the above technical solution and adding 1,2-hexanediol and p-hydroxyacetophenone, the preservative effect is better, while the irritation is lower and the safety is higher.

[0030] 2.93-3.67 parts of auxiliary agent;

[0031] Solvent: 64.62-70.62 parts.

[0032] By adopting the above technical solutions, the eye cream can effectively replenish the skin's moisture, quickly eliminate free radicals, inhibit elastase, promote skin revitalization, and accelerate the repair of the skin barrier, resulting in healthier skin. After the moisturizers in the eye cream are depleted, the repair of the skin barrier prevents moisture loss and avoids the skin from quickly becoming dry, thus achieving better anti-wrinkle effects and meeting consumer needs.

[0033] Preferably, the moisturizer is a compound of glycerin, sodium hyaluronate, carbomer, dipotassium glycyrrhizate, isohexadecane, cetearyl alcohol, hydrogenated polyisobutylene, polydimethylsiloxane, cetyl ethylhexanoate, shea butter, butylene glycol, and tetrahydromethylpyrimidine carboxylic acid in a mass ratio of 4.5-5.5: 0.1-0.12: 0.18-0.22: 0.18-0.22: 2.8-3.2: 1.7-1.9: 4.5-5.5: 4.5-5.5: 2.8-3.2: 0.4-0.6: 2.8-3.2: 0.18-0.22.

[0034] By adopting the above technical solution, through the compounding of glycerin, sodium hyaluronate, carbomer, dipotassium glycyrrhizate, isohexadecane, cetearyl alcohol, hydrogenated polyisobutylene, polydimethylsiloxane, cetyl ethylhexanoate, shea butter, butylene glycol, and tetrahydromethylpyrimidine carboxylic acid, the skin can be effectively moisturized and dryness can be quickly relieved.

[0035] Preferably, the antioxidant is a compound of meadowfoam seed oil, tocopheryl acetate, arginine, and panthenol in a mass ratio of 0.9-1.1:0.18-0.22:0.18-0.22:0.4-0.6.

[0036] By adopting the above technical solution, the combination of meadowfoam seed oil, tocopheryl acetate, arginine, and panthenol can further enhance the antioxidant effect and improve the free radical scavenging effect.

[0037] Preferably, the additives are compounded from ammonium acryloyldimethyl taurate / VP copolymer, disodium EDTA, glyceryl stearate, PEG-100 stearate, p-hydroxyacetophenone, 1,2-hexanediol, and fragrance in a mass ratio of 0.65-0.75:0.04-0.06:0.7-0.8:0.7-0.8:0.4-0.6:0.4-0.6:0.04-0.06.

[0038] By adopting the above technical solution and adding ammonium acryloyl dimethyl taurate / VP copolymer, disodium EDTA, glyceryl stearate, PEG-100 stearate, p-hydroxyacetophenone, 1,2-hexanediol, and fragrance, the product quality is more stable and the user experience is better.

[0039] Preferably, the whitening agent is nicotinamide adenine dinucleotide, and the solvent is water.

Then, they took an appropriate amount of eye cream and applied it evenly to the skin around their eyes. The experiment lasted for 90 days.

[0164] Before starting the experiment, cleanse the face with water and a disposable face towel, then measure the skin moisture content at the corner of the eyes and record it as the initial skin moisture content before the experiment. Do not apply any skin care products and allow free movement for 2 hours. Measure the skin moisture content at the corner of the eyes again and record it as the skin moisture content 2 hours before the experiment. Calculate the skin moisture loss over time before the experiment using the following formula.

[0165] Skin moisture loss over time before the experiment = initial skin moisture content before the experiment - skin moisture content 2 hours before the experiment.

[0166] When testing skin moisture content, a Corneometer CM825 skin moisture meter was used.

[0167] After detecting the initial skin moisture content, the PRIMOS rapid three-dimensional skin imaging system was used to detect skin wrinkles at the corners of the eyes, and the results were recorded as the wrinkle measurement values ​​before the experiment.

[0168] After using the eye cream continuously for 90 days, volunteers were tested again on the 91st day. First, their faces were cleansed with water and disposable face towels. Then, the skin moisture content at the corners of their eyes was measured and recorded as the initial skin moisture content after the experiment. No skin care products were applied, and the volunteers were allowed to move freely for 2 hours. The skin moisture content at the corners of their eyes was measured again and recorded as the skin moisture content 2 hours after the experiment. The skin moisture loss over time after the experiment was calculated using the following formula.

[0169] Skin moisture loss over time after the experiment = initial skin moisture content after the experiment - skin moisture content 2 hours after the experiment.

[0170] After detecting the initial skin moisture content, the PRIMOS rapid three-dimensional skin imaging system was used to detect skin wrinkles at the corners of the eyes, and the results were recorded as the wrinkle measurement values ​​after the experiment.

[0171] The experimental data for Experiment 3 are detailed in Table 2.

[0174] As shown in Table 1, all embodiments and comparative examples have good scavenging effects on dpph free radicals and can play a significant antioxidant role. They also have good inhibitory effects on elastase and can play a good role in promoting the recovery of elastic fibers. Moreover, the dpph free radical scavenging rate and elastase inhibition rate of each embodiment are higher than those of the comparative examples.

[0175] As shown in Table 2, the skin moisture loss over time in each application case after 90 days of use was significantly lower than that in the control application cases. This indicates that each application case has a better effect on promoting skin barrier repair, can significantly improve the skin's water-locking ability, prevents moisture loss, and makes the skin less prone to dryness, thus resulting in better anti-aging effects.

[0176] Table 2 shows that after 90 days of use, the reduction in skin wrinkle measurements in each application case was significantly greater than that in the control cases. Combining Tables 1 and 2, although the control cases had better antioxidant and elastin fiber repair effects, their skin barrier repair effects were relatively weak. During the experiment, volunteers could only use eye cream twice a day, morning and evening. As a result, the eye cream on the skin surface was depleted during free movement and could not be replenished in time. This depletion of moisturizers prevented them from providing further hydration, leading to dryness and continued skin damage. Consequently, some of the repair effects were negated, resulting in a lower wrinkle reduction effect compared to the application cases.

[0177] It is evident that the combination of extracts from *Chlorophytum comosum*, *Buddleja officinalis*, *Bletilla striata*, *Edelweiss*, *Ganoderma lucidum*, and ginseng can simultaneously achieve antioxidant effects, promote the repair of elastic and supple fibers, and promote the repair of the skin barrier. Through the synergistic effect of multiple functions, the speed of wrinkle smoothing can be significantly improved, better meeting consumers' demand for rapid wrinkle smoothing.

[0178] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
