Background

Acne marks, pits, and sensitive skin barrier conditions remain behind after acne, which are of greater concern to the patient than acne. Regardless of the location of the pigmentation, if the underlying factors are not adequately controlled, the pigments darken or spread, which is often long-term and recurrent, potentially causing skin color changes and psychological damage to the patient. Acne patients are prone to pigmentation and tissue damage, and in the early stages the skin is reddish, which is associated with the continued presence of inflammation after resolution of the acne, leading to vasodilation and the presence of red spots in the high tide and resolution phases of inflammation development. The black acne marks are pigmentation caused after inflammation, inflammatory factors stimulate melanocytes and induce melanocytes to synthesize and transport melanin to surrounding keratinocytes, darkening the skin exterior, which may also be permanent. In addition, during inflammation, inflammatory cells secrete degrading enzymes, decompose collagen, elastin, hyaluronic acid and other tissues in dermis, cause dermis injury and thus make skin dent, and form acne pits; at the same time, the residue of the acne marks and the acne pits is also often accompanied by the skin problem of large pores.

In the prior art, a plurality of acne-removing products exist, such as natural components from some sources, such as plant extracts, have the characteristics of anti-inflammatory, bacteriostasis and repairing, but the existing plant extract raw materials or products have weak pertinence to acne marks, especially the repairing effect on acne pits is incomplete and not ideal, and the problem of large pores caused by the existence of the acne marks and the acne pits cannot be solved.

Remarks: * The differences were statistically significant (p < 0.05) compared to the model group

As can be seen from table 4, when the technical scheme of the invention is adopted, the obtained guaiac composition can effectively inhibit the inflammatory reaction of keratinocytes, reduce the TNF-alpha content, and has remarkable effect compared with the model group; the inhibition of inflammatory factors by the resulting guaiacum composition is significantly reduced when either one of onion extract, plant ecdysteroid, guaiacum extract, VC derivative or light black giant seaweed extract is absent, and the effect obtained when other similar components are substituted is far from that obtained by the technical scheme of the present invention.

Effect example 3

The effect examples of the invention verify the improvement effect of the emulsion prepared by application examples 1-12, comparative application examples 1-11 and blank application examples on the rat scar model; the method specifically comprises the following steps:

200 SPF-grade SD rats, male, were selected and offered by Guangdong Vetolihua laboratory animal technologies Inc. After purchasing, 8 animals are fed in each cage of the barrier environment animal house, and the animals are used after quarantine is qualified.

After the rats were anesthetized and shaved on the back, after the rats entered deep anesthesia, 2 circular wounds of 7mm were created in the shaved area on the back of the rats using a skin punch, the thickness of the wound being the whole layer of skin. 1 course of treatment per week, each course of treatment was applied for 5 days, and the positive control was human epidermal growth factor gel. Photographs were taken with steel ruler comparisons on the day of molding, day 7 and day 14, respectively. Animals were euthanized on day 14, skin wound was harvested, fixed with fixative, transected and tableted, and HE stained for qualitative analysis of wound inflammation and neonatal tissue status. The healing of days 12, 13 and 14 was measured using Image-Pro Plus 6.0, and the rate of healing was 100%, which was regarded as healing, and the number of mice healed on days 12, 13 and 14 was calculated as the ratio.

Wherein the healing rate (%) = (AO-At)/ao×100%

AO: area of initial wound surface;

At: residual wound area at each time point.

The results obtained are shown in Table 6;

meanwhile, in the pathological scoring of skin injury on the 7 th day, the degree of epithelial necrosis, leukocyte infiltration, neovascularization and skin edema of mice in different groups are experimentally evaluated, and scoring is carried out according to the pathological scoring in the table 5, and the average value is obtained; the results obtained are shown in Table 6;

TABLE 5

TABLE 6

As can be seen from table 6, the emulsion obtained by the technical scheme of the invention has excellent wound healing rate, wherein the 14d healing rate can reach 87.50%; and from the skin injury pathological score of the 7d, the technical scheme of the invention can obviously improve the skin state, lighten the conditions of epithelial necrosis, erosion and leukocyte infiltration, namely obviously improve the inflammatory condition of the skin, promote angiogenesis, effectively improve the skin edema phenomenon and promote skin healing regeneration. When the guaiacum composition obtained in comparative application examples 1 to 5, either lacks any one of onion extract, plant ecdysteroid, guaiacum extract, VC derivative or light black giant seaweed extract, the rate of wound healing by the obtained emulsion is significantly reduced when the guaiacum composition is added to the emulsion; and when the efficacy components used in the added guaiac composition of comparative application examples 6 to 9 are not the components in the present invention but other similar components, the effect obtained by adding them as a whole into the emulsion is far less than that obtained by adopting the technical scheme of the present invention; when comparative application examples 10 to 11 used other effective components having a certain wound repair ability in place of the guaiac composition of the present invention in equal amounts, the effect of the obtained emulsion was also significantly reduced.

In addition, as shown in fig. 1, the result of the scar repairing effect of the emulsion in application example 6 on mice is shown in fig. 1, and it is obvious from fig. 1 that the emulsion provided in application example 6 can obviously promote skin regeneration, improve healing repairing force, improve inflammation, promote angiogenesis and improve skin edema.

Effect example 4

The effect example of the invention verifies the stimulation release rate of the emulsion prepared by application example 1, application examples 6-12, comparative application examples 1-11 and blank application examples on zebra fish embryo; the capsaicin pathway on human skin can be activated by capsaicin, acidity and temperatures above 42 ℃. Zebra fish also have capsaicin pathways and can be activated at high temperatures, peaking at 37 ℃ or above, exhibiting a significant increase in swimming speed. Therefore, the motion distance reduction rate is calculated by applying the motion distance change of the zebra fish and the zebra fish embryo of the model control group activated at high temperature to evaluate the soothing effect of the raw material or the product, and the larger the motion distance reduction rate is, the better the soothing effect is.

The wild type AB strain zebra fish (Danio rerio) test with reliable source (such as China national zebra fish resource center) is applied. The experimental steps are as follows:

healthy 5-day post-fertilization large zebra fish embryos were selected in 96-well plates and exposed to each experimental group, with model controls: randomly selecting 16 fish embryos into 96-well plates, wherein each well contains one fish embryo and 0.2mL of fish embryo culture solution, and the positive control group: 16 fish embryos are randomly selected into 96-well plates, each well containing one fish embryo and 0.2mL of 0.05 g/L4-t-butylcyclohexanol solution, sample group: 16 fish embryos are randomly selected into 96-well plates, each well containing one fish embryo and 0.2ml of 20g/L sample solution (samples were directly lysed with fish embryo culture solution to prepare test sample solutions). After 2h exposure at 28℃the swimming track of each zebra fish in the dark was recorded as the movement distance and statistically analysed using Ethovision XT IR tracking software in a Daniovision zebra fish movement recorder which had been preheated to 38 ℃.

Data and result calculation: measuring and reading the pixel intensity of each hole as the movement distance of each fish embryo;

calculating a motion distance reduction rate: reduction rate= (M-S)/mx100%;

s: average value of the movement distance of the fish embryo of the test object treatment group;

m: average value of embryo movement distance of model group fish.

The results obtained are shown in Table 7;

TABLE 7

/>

As can be seen from Table 7, when the technical scheme of the invention is adopted, the obtained emulsion can remarkably shorten the movement distance of the zebra fish embryo, and the reduction rate is more than 27%. When the guaiacum composition obtained in comparative application examples 1 to 5, whether it lacks any one of onion extract, plant ecdysteroid, guaiacum extract, VC derivative or light black giant seaweed extract, was added to the emulsion, the effect of the obtained emulsion on relieving stinging was significantly reduced; and when the efficacy components used in the added guaiac composition of comparative application examples 6 to 9 are not the components in the present invention but other similar components, the effect obtained by adding them as a whole into the emulsion is far less than that obtained by adopting the technical scheme of the present invention; when comparative application examples 10 to 11 used other similar functional components in place of the guaiac composition of the present invention in equal amounts, the effect of the resulting emulsion was also significantly reduced.

In addition, the graph of the result of the emulsion in application example 6 on the movement distance of the zebra fish embryo at high temperature is shown in fig. 2, and it can be obviously seen from fig. 2 that the emulsion provided in application example 6 can remarkably reduce the movement distance of the zebra fish embryo, so as to achieve the effect of relieving stinging.

Effect example 5

The effect examples of the present invention verify the safety of application example 1, application examples 6 to 12, comparative application examples 1 to 11 and blank application examples on human skin. According to the human skin patch test (cosmetic safety technical Specification) (2015), 33 volunteers 18-60 years old are recruited in the test, and the test environment is the temperature (21+/-1) DEG C and the humidity (50+/-10)%. The volunteer cleans the forearms with clear water, after 5-10 minutes, after the moisture of the forearms volatilizes, the tester applies 0.020-0.025 mL of each group of sample emulsion to each cell of the 10-hole spot tester, selects the inner sides of the two forearms of the volunteer, avoids the skin at the joint movement positions of the front and rear hands, each arm is respectively attached with the spot tester with the sample, and makes corresponding marks, the patch time lasts for 24 hours, the spot tester is removed to wipe residual samples, skin reactions of 0.5 hours, 24 hours and 48 hours are observed, and the results are recorded according to the skin reaction grading standard in cosmetic safety technical Specification (2015). Skin reactions were classified into 4 scoring scales as in table 8, with higher severity of skin irritation reactions as the score was higher.

The test results are shown in Table 9, and it is clear from the test results that the invention provides 0 cases of withdrawal and 0 cases of allergy to rubberized fabric in the technical scheme. When the guaiacum composition obtained in comparative application examples 1 to 5, either lacks onion extract, plant ecdysteroid, guaiacum extract, VC derivative or light black giant seaweed extract, was added to the emulsion, the emulsion obtained had a certain irritation; and when the efficacy ingredient used in the added guaiac composition of comparative application examples 6 to 11 is not the component of the present invention but other similar components, the effect obtained by adding it as a whole to the emulsion is far less than that obtained by adopting the technical scheme of the present invention, wherein application examples 7 to 8 show a 1-stage reaction within 0.5h, application examples 9 to 11 show a 1-stage reaction in an amount of 3 or more within 0.5h, whereas comparative application examples 1 to 11 show a 1-stage reaction in an amount of 5 or more within 0.5h, respectively. In contrast, application examples 6 to 8 and application example 12 were milder and safer, with application example 6 and application example 12 being non-irritating; wherein the picture during the actual test is shown in fig. 3.

Effect example 6

The effect examples of the invention verify the application effects of application examples 6-11 and blank application examples for improving acne marks on human bodies, wherein red acne marks and black acne marks are respectively generated in the early stage and the later stage of acne mark formation, the red acne marks are vascular dilatation and inflammatory reaction caused by long acne marks, and if the red acne marks are not maintained or removed in time, the skin is gradually deepened into black acne marks, and the black acne marks are intractable and easy to relapse. The red and black acne marks can be identified according to naked eye identification or non-invasive instrument detection. The present invention was therefore targeted towards the colour exhibited by the acne marks at different times.

The method specifically comprises the following steps:

according to the test of cosmetic safety technical Specification (2015), 80 Asian adult testers 18-60 years old, 10 people in each group, with more obvious acne marks, are selected, under normal conditions, the volunteers continuously use the product for 28 days on the whole face, and the acne mark removing efficacy of different groups of products is evaluated by taking the product containing 3% of nicotinamide (comparative application example 10, which has a great deal of research shows that the nicotinamide lightens pigment, accelerates the exfoliating of horny substances and promotes metabolism to play a role) as a positive control. The method comprises the following specific steps:

the volunteers use the lotion for 1 time in the morning and evening after moisturizing the face, and the lotion is smeared on the acne marks and the acne pits, the massage and the absorption are carried out, and the whole face is used for 1 time in the morning and evening, and the group of 10 people is accessed again in days 3, 7, 14, 21 and 28. The volunteers were not smeared with any product after visiting the test area on the same day and washing the face, and were sitting still for 20min in an air-conditioning room with a temperature of 21+ -1deg.C and a humidity of 50+ -10%. And quantifying and photographing different types of acne marks by adopting an instrument, wherein the values of a are measured by VISIA7, the values of heme content EI and melanin content MI are measured by MX18, and the acne mark area is measured by VISIA7 and IPP. The change in a and EI values may represent the improvement in red blemishes, with smaller data representing more pronounced red blemishes fading; the change in MI value may be indicative of the degree of improvement in black blemish, with smaller values indicating more pronounced black blemish fade. The improvement of the acne marks is represented by the improvement rate of each numerical value in the test, and the calculation mode is as follows:

Mean improvement rate with respect to blank value= (X _{Before-use mean value} -X _{Mean value after use} )/X _{Before-use mean value} ×100％；

The results obtained are shown in Table 10;

table 10

Remarks: * The difference was statistically significant (p < 0.05) compared to the blank value

As can be seen from table 10, the emulsion prepared by the invention can effectively inhibit inflammatory erythema and pigmentation, reduce the area of red and black acne marks, inhibit the conversion of red acne marks into black acne marks and solve the recurrence of acne marks; the effect is obviously better than that of the emulsion added with the nicotinamide, and the acne marks are blackened when the emulsion added with the nicotinamide is not subjected to sun-screening treatment in the use process, the blackened phenomenon of the emulsion does not occur, the emulsion provided by the invention not only stays on the basis of fading the acne marks, but also can obviously reduce the average area of facial color spots, and the effects of homogenizing the facial complexion and improving the facial texture are achieved.

In addition, as shown in fig. 4, the result of the improvement of the emulsion in application example 6 on the red and black acne marks on the face of the human body is shown in fig. 4, and it is obvious from fig. 4 that the emulsion provided in application example 6 can obviously lighten the red and black acne marks and reduce the average area of the facial color spots.

Effect example 7

The effects of the invention prove the application effects of application examples 6-11 and blank application examples on the human body, namely, the effects of smoothing acne pits and refining pores, wherein the acne pits are serious in acne marks, and the skin is usually concave or collapses due to damage to dermis caused by external extrusion, so that the acne marks are easy to be in a permanent state. In addition, loss of collagen and imbalance in oil secretion due to reduced skin elasticity cause problems of enlarged pores after acne, affecting facial gloss and flatness. The experiment uses palmitoyl pentapeptide-4 (comparative application example 11) as a comparison, and the prior study shows that the palmitoyl pentapeptide-4 can obviously promote the generation of dermal matrix protein and help rebuild skin; promoting keratinocyte differentiation and maturation, promoting skin epithelia formation, increasing horny layer thickness and strengthening barrier layer of healthy skin, and has effect in eliminating acne pits.

The method specifically comprises the following steps:

80 subjects with acne pits on the face of 18-60 years old are selected according to the test of cosmetic safety technical Specification (2015), randomly divided into 8 groups, 10 persons in each group use the same product on the random whole face, and palmitoyl pentapeptide-4 (comparative application example 11) is used as a sample of an acne pit control group for 28 days, and the return visit is carried out on days 7, 14 and 28. 10 people, group 1. The volunteers visit the test area on the same day, clean the face without smearing any product, shoot the face image situation (VISIA 7& Primos CR) after sitting still for 20min in an air conditioning room with the temperature of 21+/-1 ℃ and the humidity of 50+/-10%, analyze the red area of the skin, the acne pit volume, the wrinkle depth, the wrinkle volume and the pore number, and the test shows the improvement situation of the acne pits and the pores by the improvement rate of each value, and the calculation mode is as follows:

The results obtained from the test are shown in Table 11;

TABLE 11

As can be seen from table 11, the technical scheme of the invention can obviously reduce skin redness, slow down subcutaneous inflammation, reduce the volume of acne pits, fill skin, fine pores and smooth skin; when the guaiac composition is not added in the blank application example, the guaiac composition cannot play roles of removing acne pits, reducing skin inflammation and refining pores, and the number of the acne pits and pores instead shows a more serious trend along with the time; meanwhile, compared with comparative application example 11, the technical scheme provided by the invention also shows obvious advantages.

Further, the results of the lotion of application example 6 on repairing and refining the pits and pores of the human face are shown in fig. 5 and 6. The emulsion provided in application example 6 in the experimental result not only can obviously remove acne marks and fill the skin to achieve the effect of preventing acne pits (shown in fig. 5A), but also has remarkable effect of repairing the existing facial acne pits (shown in fig. 5B). Furthermore, it can be seen from fig. 6 that the number of detectable pores is significantly reduced. Therefore, the lotion provided in application example 6 can obviously repair acne pits, reduce skin pits and textures after acne, reduce the number of detectable pores, refine pores and smooth skin.

Finally, it should be noted that the above-mentioned embodiments illustrate rather than limit the scope of the invention, and that those skilled in the art will understand that changes can be made to the technical solutions of the invention or equivalents thereof without departing from the spirit and scope of the technical solutions of the invention.
