Description

Whitening skin-care mask mud and preparation method thereof
Technical Field
The invention relates to the technical field of cosmetics, in particular to whitening and skin-care mask mud and a preparation method thereof.
Background
Skin whitening is one of the traditional aesthetic standards of Chinese females, many females hope to achieve the whitening effect by using a functional whitening skin care product, the whitening product has great market value at home and abroad, but the infrared ray causes the up-regulation of MMP-1 gene in a human body, the MMP-1 is a regulation gene of collagen degrading enzyme, and the degradation of collagen is a main factor of the premature senility of human skin. Meanwhile, the hyperpigmentation of melanin causes skin problems such as spots, freckles, etc., and affects the skin quality of the skin.
The currently accepted process of melanogenesis can be briefly expressed as: tyrosine-dopa-dopaquinone-dopachrome-dihydroxyindole-ketoindole-melanin, the formed melanin is eumelanin or eumelanin, and the skin pigment mainly consists of the eumelanin. Since the formation of melanin occurs mainly in melanocytes, studies on the mechanism of melanin formation in melanocytes have shown that the formation of melanin is mainly due to the inclusion of four enzymes in melanocytes: tyrosinase, dopachrome tautomerase (TRP-2), peroxidase and DI-IICA oxidase (TRP-1), which stabilize tyrosinase activity, which is different from tyrosinase of mice, mushrooms, etc., in human body, and the above four enzymes act individually or synergistically. Inhibition of various melanin-forming enzymes is important if true skin lightening is to be achieved.
Among the various melanin-forming enzymes mentioned above, tyrosinase is a polyphenol oxidase, which belongs to the class of redox enzymes that catalyze mainly two different types of reactions: hydroxylating the monophenol to generate an ortho-dihydroxy compound, and oxidizing the ortho-diphenol to generate ortho-diphenoquinone. In both reactions, oxygen free radicals participate. Tyrosinase is the main rate-limiting enzyme in the process of melanin formation, and the size of the enzyme activity determines the amount of melanin formation. Therefore, the purpose of inhibiting the formation of melanin can be achieved by destroying the active site of tyrosinase.

The preparation method of the whitening and skin-care mask mud is the same as that of the embodiment 1.
The inhibition effect of the composition prepared in example 5 on the up-regulation of MMP-1 gene after infrared light irradiation is shown in Table 1.
In order to verify the whitening effect of the product, the following comparative test formula is carried out for a comparative experiment:
formula 1: the mulberry leaf flavone, phloretin and lycium barbarum polysaccharide are respectively replaced by the same amount of second-level purified water, and the composition and preparation method of other components are the same as those in example 1.
And (2) formula: neohesperidin dihydrochalcone and baicalin were replaced with the same amount of second-stage purified water, and the composition and preparation method of the other components were the same as those in example 1.
And (3) formula: the composition and preparation of all components are the same as in example 1.
Volunteers: randomly selecting 30 healthy male and female volunteers, wherein the male and female volunteers are 18-65 years old, have no serious system diseases, no immune defects or autoimmune diseases, have no allergic diseases, do not use various cosmetics and the like during a test period, and can finish the use of specified samples according to experimental requirements. The experimental method comprises the following steps: the volunteers are divided into 3 groups according to the formula, 10 persons are in each group, the 3 groups of the formula are subjected to a trial test on the volunteers for 28 days, the volunteers are used for 1 time every other day at night, and the trial part is the face. Testing an instrument: a skin elasticity CotometerMPA580 host manufactured by CK company, germany; skin melanin mexamettmx 18 test probe manufactured by CK company, germany. Face test conditions: the face test was performed indoors with no intense sunlight or direct lighting. Whitening products (including other cosmetics, external medicines or internal health care products) cannot be used 2-3 days before the test. The subjects required a uniform cleansing of facial skin and a clean wipe with dry tissue prior to testing.
Based on the principle of spectral absorption, the content of melanin in the skin is determined by measuring the reflection amount of light with a specific wavelength irradiated on the skin of a human body. The test probe of the pigment detector consists of a light source emitter and a light source receiver, and a spring is additionally arranged to keep the pressure on the skin constant during detection. The transmitter of the probe emits light with three wavelengths of 568nm, 660nm and 880nm to the surface of the skin, and the receiver measures the light reflected by the skin. Since the amount of emitted light is constant, the amount of light absorbed by the skin can be measured, and the amount of melanin in the skin can be measured. The data in table 2 are the skin melanin content determined.

From the above data, it can be seen that the mean value of skin melanin content of the volunteers after the 28-day test period of formula 2 decreased by 11.1, and the skin whitening trend was significant (P < 0.05).
And (3) formula:

From the above data, it can be seen that the mean value of skin melanin content of the volunteers after the 28-day test period of formula 3 decreased by 21.7, and the skin whitening tendency was significant (P < 0.05).
The above experimental results show that the skin melanin content of the volunteers is reduced after the test period of 28 days by the 3 test formulas, and the skin whitening trend is obvious, wherein the skin melanin content of the volunteers is reduced most obviously after the test period of 28 days by the formula 3, and the effect is obviously better than that of the former two groups of formulas. Consumer tests show that the whitening skin-care mask mud has an obvious skin-whitening effect by combining and compounding 5 main components of neohesperidin dihydrochalcone, baicalin, mulberry leaf flavone, phloretin and lycium barbarum polysaccharide, and the whitening effect is superior to that of a formula in which neohesperidin dihydrochalcone and baicalin are compounded alone or a formula in which mulberry leaf flavone, phloretin and lycium barbarum polysaccharide are compounded alone.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
