Description

TECHNICAL FIELD

[0001] The present application relates to the field of skin care products, in particular to a plant extraction compound with firming and anti-wrinkle effects, a preparation method and application thereof. BACKGROUND

[0002] With the development of society, people pay more and more attention to skin health, among which, the problem of wrinkles is one of the skin problems that people pay more attention to, therefore, skin care products with anti-wrinkle effects are one of the more popular products.

[0003] The main causes of wrinkles are the loss of collagen in the skin, the breakage of elastin fibers, and the loss of skin moisture. Existing skin care products mainly add antioxidant ingredients to reduce the attack of free radicals on the skin, thereby reducing skin aging, making the skin recover to a certain extent, thereby accelerating the generation of collagen to resist the loss of collagen. Some skin care products also add ingredients with the effect of inhibiting elastase to promote the repair of elastin fibers, and add ingredients for skin moisturizing to supplement water, thereby achieving a certain degree of anti-wrinkle effect.

[0004] However, existing anti-wrinkle skin care products mainly focus on the effects of antioxidant and elastase inhibition, ignoring the fact that dry skin can also cause serious damage to the skin, leading to the formation of wrinkles. Although existing skin care products will add moisturizing ingredients, these moisturizing ingredients mainly supplement water to the skin by absorbing water in the air. In people's daily activities, the skin care products covering the skin surface are easily damaged, and in the fast-paced life, people are difficult to supplement the damage of skin care products by frequently using skin care products, resulting in the loss of the effect of moisturizing. People usually only remember to supplement skin care products when the skin appears obvious dryness, which leads to a cycle of continuous damage, repair, and re-damage of the skin, resulting in the anti-wrinkle effect of skin care products being not obvious, and it is difficult to meet the needs of consumers, so there is still room for improvement. SUMMARY

[0005] In order to improve the anti-wrinkle effect, the present application provides a plant extraction compound with firming and anti-wrinkle effects, a preparation method and application thereof.

[0006] In a first aspect, the present application provides a plant extraction compound with firming and anti-wrinkle effects, which adopts the following technical solution: A plant extraction compound with firming and anti-wrinkle effects, comprising the following components in mass fraction: 84.8-89.2 parts of solvent; 0.8-1.2 parts of preservative; 10-14 parts of moisturizing and anti-aging composition; The moisturizing anti-aging composition is a compound of Chondrus crispus extract, Flos Genkwa extract, Liriopis squarrosa extract, Ledum palustre extract, Ganoderma lucidum extract and Panax ginseng extract.

[0102] Table 1

[0103] Experiment 3 Several female volunteers aged 40-50 with crow's feet were recruited. The volunteers were divided into groups and used the eye creams of the application cases and control cases. They used the creams once in the morning and once in the evening. Before use, the volunteers cleaned their faces with water and disposable face towels. 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.

[0104] 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.

[0105] Skin moisture loss over time before the experiment = initial skin moisture content before the experiment - skin moisture content 2 hours before the experiment.

[0106] When testing skin moisture content, a Corneometer CM825 skin moisture meter was used.

[0107] 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.

[0108] 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.

[0109] Skin moisture loss over time after the experiment = initial skin moisture content after the experiment - skin moisture content 2 hours after the experiment.

[0110] 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.

[0111] The experimental data for Experiment 3 are detailed in Table 2.

[0112] Table 2

[0113] As shown in Table 1, all embodiments and comparative examples have a uniform and good effect in scavenging dpph free radicals, and can play a significant antioxidant role. At the same time, they all have a good effect in inhibiting 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.
