Description

Essence for repairing sensitive skin and preparation method thereof

Technical Field

The invention belongs to the technical field of cosmetics. More particularly, to essence for repairing sensitive skin and a preparation method thereof.

Background

Sensitive skin generally has the following characteristics due to environmental factors, seasonal changes and excessive improper use of facial skin care products leading to the appearance of more and more sensitive skin: the skin is light and thin, dry and water-deficient, and contains more obvious red blood streak; secondly, the skin is easily reddened, heated, irritated and itching caused by temperature change and seasonal change; thirdly, the skin has poor water retention and is obviously tense and dry.

The passionflower is various in types, and the most common species are passionflower pink (p.incarnata) and passionflower purple (p.edulis), wherein the main component of the passionflower pink is flavonoid which mainly exists in leaves, and the leaves also contain high isovitexin and a small amount of indole alkaloid, essential oil, saccharide and maltol; the passion fruit leaves contain more isoorientin (not found in passion fruit pink) and also contain essential oils and alkaloid species similar to passion fruit. Researches show that the extract of passion fruit or flower tip has the effects of scavenging free radicals and resisting oxidation, so that the extract is mostly applied to preparing anti-aging products, but the extract is not applied to improving skin sensitivity symptoms.

The tomato extract contains abundant vitamins, organic acids, alkaloids and flavonoids, wherein the vitamins include carotene and vitamin B₁Vitamin B₂Vitamin A, vitamin C, vitamin D, lycopene, etc.; the organic acids are mainly citric acid and malic acid. The tomato extract obtained by crushing fresh tomatoes into tissue and then taking juice has better antibacterial property and oxidation resistance, and the proliferation effect of the tomato extract on epidermal cells and the activation effect on cathepsin show that the tomato extract can enhance the metabolism of skin cells, can be applied to the preparation of anti-aging cosmetics in combination with the oxidation resistance, and is rarely applied to the improvement of skin sensitivity.

At present, most of products for repairing sensitive skin on the market are compounded by two or more plant extracts, but the compounding of different plant extracts can not bring the superposition of anti-sensitivity effects, and the mutual antagonism is reflected for a lot of time, and even the skin sensitivity is aggravated. Therefore, it is not easy to obtain a skin care product with synergistic effect for repairing sensitive sources.

Test example I skin barrier function repair test

The repairing effect of each skin care essence on the skin barrier function is evaluated by detecting the TEWL value of the skin.

1. The test method comprises the following steps: selecting 100 female volunteers, wherein each group of test subjects have no systemic diseases and other skin diseases, other skin care products are not used in one week, and the females are not in the gestation period or the lactation period and voluntarily participate in the whole course of the test; 100 subjects were randomly divided into 10 groups of 10 subjects, the essences prepared in examples 6 to 10 and comparative examples 1 to 5 were applied to the subjects, the product was applied twice a day, once in the morning and at night, and continuously applied for 28 days, the TEWL values of the subjects in each group before and after application were measured by a Tewameter tester, the measurement was performed continuously for each time, the reading period was 1 second, the measurement was performed for 1 minute, and the average of 60 data was measured as the transdermal water loss rate (g/hm)²) The test results are shown in table 1 below. And (3) testing environment: the test is carried out in a room with the temperature of 22-25 ℃ and the relative humidity of 35-45%, and each group of testees enter a test room to rest for 30 minutes and then start the test.

TABLE 1 changes in skin TEWL values

Note: a smaller TEWL value indicates a better skin barrier function and better repair.

Rate of change ═ skin TEWL value-pre-use TEWL value on day 28)/pre-use TEWL value × 100%

As can be seen from the above table, the skin TEWL values of the subjects in each group before use were mostly 22g/hm²The above is the description of the skinThe barrier is damaged to different degrees, and after the skin care essence of the invention of 6 to 10 is used for 28 days, the skin barrier function of each group of subjects is obviously enhanced compared with that before the skin care essence is used, and the skin TEWL value of each group of subjects is stabilized at 12 to 15g/hm²The skin barrier function is good, which indicates that the composition of the tomato extract yeast fermentation product and passion flower callus culture cells and/or the extract thereof has a repairing effect on the skin barrier function; and when the tomato extract yeast fermentation product and the passion flower callus culture cell extract act independently, the skin barrier repair effect is not ideal, which shows that the tomato extract yeast fermentation product and the passion flower callus culture cell extract have synergistic effect on the aspect of repairing the skin barrier function.

Test example two skin Red pigment analysis

TABLE 2 changes in skin Red pigment

The above table shows that after the skin care essence of examples 6-10 of the invention is used for 28 days, the skin redness of each group of subjects is obviously reduced compared with that before the skin care essence is used, wherein the skin redness is reduced by more than 17% through the excellent effects of examples 6-10. The combination of the tomato extract yeast fermentation product and the passion flower callus culture cells and/or the extract thereof has a good effect of improving the skin erythema, and the effect is obtained by the synergy of the two.

Test example three, Red blood streak removal test

The method comprises the steps of selecting 110 volunteers with red blood strips on the face, wherein the average age is 32 years old, randomly dividing the volunteers into 10 groups, using the essence prepared in examples 6-10 and comparative examples 1-5 for 11 persons in each group, using the product twice a day, once in the morning and evening, and continuously using the essence for 28 days, photographing and archiving the red blood strips on the face before and after use by using a VISA skin tester, and evaluating the change condition of the red blood color, wherein the evaluation result is shown in the following table 3.

Evaluation criteria: more than 30% of red blood streak is removed as obvious effect; 5-30% of red blood streak is effectively removed; less than 5% of red blood streak removed or not significantly ineffective.

TABLE 3 Red blood streak changes

Sample (I)	Total number of cases	Number of cases/effects	Effective/number of cases	Number of invalid/instances
					Example 6	11	9	2	0
