Description

Composition with effects of moisturizing, repairing skin barrier, resisting wrinkles and tightening skin, preparation method and application thereof

Technical Field

The invention belongs to the field of cosmetics, and particularly relates to a composition with effects of moisturizing, repairing skin barriers, resisting wrinkles and tightening, and a preparation method and application thereof.

Background

Aging, prolonged exposure to adverse environmental factors, nutritional disorders, fatigue, etc. can alter the visual appearance, physical properties, or physiological functions of the skin, all of which are undesirable. The most significant and obvious changes include the formation of fine lines and wrinkles, reduced elasticity, sagging skin, reduced firmness, no longer uniform or dull skin tone, rough skin surface texture, and the appearance of color patches. Changes that occur as skin ages or experiences long-term environmental damage include a general decrease in cellular and tissue activity, a decrease in the rate of cell replication, a decrease in skin blood flow, a decrease in moisture content, the accumulation of structural and functional errors, changes in skin metabolism, and a decrease in the ability of the skin to rebuild and repair itself. These changes, although less pronounced, can also be assessed by some method of measurement. Many changes in the appearance and barrier function of the skin are primarily caused by changes in the outer epidermal layer of the skin, while other changes, such as wrinkles and skin laxity, are primarily caused by changes in the underlying dermis.

In order to prevent these phenomena and maintain healthier and more elastic skin, efforts have been made to prepare cosmetics containing various highly effective active substances for maintaining the inherent functions of the skin and activating skin cells, thereby effectively slowing down skin aging. However, most of the conventional cosmetic materials have various problems such as single efficacy, insufficient efficacy, and easily induced skin side effects.

The efficacy of the cosmetic raw materials in the current market is often single, and a formulator needs to blend a plurality of cosmetic raw materials together according to experience, so that the target cosmetic can have multiple efficacies, but the work depends on the experience of the formulator to a great extent, the success rate is low, and the problem that the efficacy of the target cosmetic becomes worse after the plurality of cosmetic raw materials are combined together often easily occurs.

Effect embodiment:

effect example 1: testing of the Effect of the compositions of the present invention on skin moisturization

Skin moisture retention was measured in 21 volunteers (3 per group) using a skin moisture tester Corneometer CM 825 (Courage Khazaka, germany). The samples were applied to test areas marked 4cm × 4cm on the left and right anterior flexor sides of the subject, respectively. The coating amount is 3.0mg/cm ² Gently massage until the sample is absorbed. Measuring skin moisture content before and 4 hr after smearing with skin moisture meter, calculating skin moisture content increase rate according to the following formula, and averaging skin moisture content increase rates of volunteers using the samples to obtain the sampleAverage skin moisture content increase rate of the product.

Skin moisture content increase (%) = (measured value after application-base value before application)/base value before application x100%

The results of the experiment are shown in table 1:

table 1: effect of the compositions of the present invention on skin moisturization

Group of	Skin Water content increase (%)
		Example 2	42.75
Example 4	48.23
		Comparative example 1	15.48
Comparative example 2	20.16
		Comparative example 3	43.51
Comparative example 7	7.14

As can be seen from the data in table 1, the skin moisturizing effect was poor with the conventional cosmetic base used alone for preparing the cream, and the mean skin moisture content increase rate was only 7.14% in the volunteers of comparative example 7 group at 4 hours.

The combined use of part a and part B (see results of example 2) can significantly increase the skin moisturization of the volunteers compared to parts a and B used alone (see results of comparative examples 1 and 2).

In addition, the addition of part C to the combination of parts a and B more significantly increased the skin moisturization of the volunteers (see results of example 4). Also, the kinds of the various natural plant extracts in part C have a great influence on the skin moisturizing effect of volunteers (see the results of example 4 and comparative example 3).

Effect example 2: skin Barrier function repair test with the composition of the invention

2.1 test subjects:

70 skin allergic subjects, 35 each for men and women, aged between 18 and 50 years, were randomized into 7 groups (10 subjects per group): example 2, example 4, comparative example 1, comparative example 2, comparative example 3, comparative example 7.

2.2 methods of use:

the corresponding face cream was used for each group of subjects.

The lotion is applied once in the morning and evening every day, and the skin allergic area is cleaned before application. The first examination was performed after 3 consecutive days and the second examination was performed after 7 consecutive days.

2.3 judging standard:

(1) The effect is shown: the skin allergy such as red swelling, pruritus and skin damage disappears.

(2) The method has the following advantages: the skin allergy such as red swelling, pruritus and skin damage is reduced.

(3) And (4) invalidation: the skin is red and swollen, pruritus, skin damage and other allergic phenomena are not obviously changed.

(4) Weighting: the skin is red and swollen, itching, skin damage and other allergic phenomena.

2.4 Experimental results:

the results of the experiment are shown in table 2:

table 2: results of the skin barrier function repair test with the composition of the invention

As can be seen from the results in table 2, the subjects in the comparative example 7 group gradually worsened the allergic symptoms during the study period due to the use of only conventional cosmetic bases for the preparation of creams.

Compared with the comparative example 1 (part A) and the comparative example 2 (part B), the repair effect of the example 2 (part A + part B) on the skin barrier function of the subjects is remarkably enhanced, the effective percentages of the subjects in the example 2 group are respectively 80% and 90% when the subjects are checked on the 3 rd day and the 7 th day, and the repair effect of the composition on the skin barrier function of the subjects shows a trend of continuously improving along with the prolonging of the use time, while the repair effect on the skin barrier function of the subjects is continuously weakened along with the passage of time after the A part or the B part is used alone.

In addition, further addition of part C to the combination of parts a and B can enhance the skin barrier repair function of the subject more significantly (see results of example 4). Also, the kinds of the various natural plant extracts in part C also have a great influence on the skin barrier repair function of the subject (see results of example 4 and comparative example 3).

Effect example 3: anti-wrinkle firming effect test of the composition of the invention

70 women of 35-65 years old were selected as subjects and divided into 7 groups of 10 persons each. Before the test, after washing the face of the subject, the subject was subjected to a constant temperature and humidity environment (temperature 21-23 ℃, humidity 55-65%) for 30min, and then subjected to facial photographing using VISA-CR as primary data, the subject applied the corresponding cream of each group to the face for 1 time per day for 30 consecutive trials, and washed the face on days 0 and 30 and then subjected to facial wrinkle test using VISA-CR, which are respectively denoted as D0 and D30. The D0 and D30 values of each group are the average value of the values of the group, the facial wrinkle improvement before and after use is calculated through instrument software, and the lower the score is, the more wrinkles are indicated. The test results are shown in table 3:

table 3: results of the anti-wrinkle Effect test of the composition of the present invention

As can be seen from the results in table 3, the subjects of the comparative example 7 group had substantially no wrinkle removing effect using only conventional cosmetic bases for preparing a cream.

As can be seen from the results of comparative examples 4 and 5, part a and part B used alone also had substantially no wrinkle-removing effect. However, after combining part a and part B, the wrinkle-removing effect on the subject was significantly enhanced at day 30, and the test score of example 3 increased to 84.5%.

In addition, the further addition of part C to the combination of part a and part B can more significantly enhance the anti-wrinkle effect on the skin of the subject (see the results of example 5), i.e., the anti-wrinkle effect on the skin of the composition of the present invention is significantly improved by the addition of the natural plant extract in a specific kind and amount ratio to the composition of the present invention. However, the kinds of the various natural plant extracts in part C also had a great effect on the anti-wrinkle effect of the skin of the subject (see the results of example 5 and comparative example 6).

In conclusion, the experimental results show that the xylitol and the derivative moisturizing factor composition thereof in a specific dosage ratio are combined with the low-molecular-weight hyaluronic silanol composition, so that the composition has the effects of synergistically moisturizing, repairing skin barriers, resisting wrinkles and tightening, and the like, the effects of the composition can be further enhanced by further adding certain natural plant extracts into the composition, and the composition can be applied to cosmetics, so that the skin cuticle reconstruction can be promoted, the skin moisturizing performance and the water resistance can be improved, the wrinkles of the skin can be reduced and tightened, and the use feeling is excellent.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
