Description

Technical Field

[0001] The invention relates to the technical field of cosmetics, and in particular to a whitening and spot-lightening composition, a whitening and spot-lightening essence milk, and a preparation method and application thereof. Background Art

[0002] As a vital tissue of the human body, the skin carries multiple key functions, such as protecting internal tissues and organs, maintaining water balance in the body, and resisting the invasion of harmful substances from the outside world. However, as we age, the body's metabolism slows down, which causes the renewal of skin cells to slow down, the skin becomes rough and dry, and pigmentation may occur. At the same time, the skin's ability to restore melanin weakens. When melanin accumulates in the lower layer of the skin, it will cause the skin to darken or develop spots. In addition, the accelerated pace of life, irregular work and rest, frequent use of electronic products, and the use of some cosmetics containing heavy metals will also promote the formation of melanin.

[0003] With the improvement of living standards, people's demand for skin care products continues to increase, especially when facing skin problems such as melanin deposition and spots, people have a strong demand for efficient, safe and natural whitening and spot removal skin care products. Traditional whitening and spot removal products mostly rely on chemical ingredients, such as hydrogen peroxide and hydroquinone, to achieve the effects of whitening and spot removal by inhibiting or interfering with the production of melanin; however, long-term use of these products can cause skin discomfort symptoms such as dryness, tightness, and tingling. In addition, these chemical ingredients may also destroy the natural barrier of the skin, making the skin more sensitive and susceptible to external stimuli. As consumers pay more attention to product safety, traditional chemical whitening ingredients are gradually replaced by safe and mild natural ingredients, but these natural ingredients are used in cosmetics. There are problems such as insufficient stability, difficulty in being absorbed by the skin, and poor appearance and skin feel of the product, which limits its wide application. Therefore, it is urgent to develop a safer and more efficient composition that achieves whitening and spot removal effects. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a whitening and spot-lightening composition, a whitening and spot-lightening essence lotion, and a preparation method and application thereof.

[0068] (II) Subjects: A total of 30 subjects, including 10 males and 20 females, aged 24-60 years old, with an average age of 39.33±10.51 years old, met the voluntary inclusion criteria;

[0069] (III) Test method: The test was conducted in accordance with the specific requirements of the Technical Specifications for Safety of Cosmetics (2015 Edition). The back of the subject was selected as the test site, and the area of ​​each blackened test area was not less than 0.5 cm 2 , and in each smeared area, determine the MED of the test site of the subject, and use a solar simulator to irradiate once a day at the same irradiation point at a dose of 0.75MEDa, and continue irradiation for 4 days. The 4 days after the end of irradiation are the melanization period, and no treatment is done. On the 5th day after the end of irradiation, the skin of each test area is visually evaluated and instrumentally tested for skin color, and test areas with poor consistency are eliminated. Starting from the 5th day, the corresponding test substance is applied to each melanization test area according to the random table, and the subjects are applied continuously for at least 4 weeks. The skin color should be visually evaluated and instrumentally tested 1 week, 2 weeks, 3 weeks and 4 weeks after application, and recorded.

[0096] Significance marking method: ("ns" indicates no statistical difference, p≥0.05; "S" indicates significant difference, P≦0.05).

[0097] From the test results of the above test examples, it can be concluded that (1) after using the experimental product of the present invention, the improvement degree of the skin ITA° value of the experimental product group was significantly better than that of the negative control group at each revisit time point (P<0.05), and the regression coefficient of the skin ITA° value of the experimental product group was significantly improved compared with that of the negative control group (P<0.05); (2) after using the experimental product, the improvement degree of the MI value of the experimental product group was significantly better than that of the negative control group at each revisit time point (P<0.05), and the regression coefficient of the skin MI value of the experimental product group was significantly improved compared with that of the negative control group (P<0.05); (3) after using the experimental product, the improvement degree of the visual skin color grade of the experimental product group was significantly better than that of the negative control group at each revisit time point (P<0.05), and the regression coefficient of the skin visual skin color grade of the experimental product group was significantly improved compared with that of the negative control group (P<0.05); In summary: the experimental results show that the tested samples have significant freckle removal and whitening effects.

[0098] Test Example 2:

[0099] This test example evaluates the ITA value, ITA value and visual skin color grade of the whitening and spot-lightening essence milk of the embodiment and the comparative example.

[0100] Test subjects: 100 female volunteers aged between 25 and 45 were randomly divided into four groups, with 25 people in each group. All volunteers had no serious skin diseases and had not used any whitening products within one month before the experiment. Before the experiment, all volunteers signed an informed consent form to ensure the ethics and legality of the experiment.

[0101] Test method:

[0102] (1) ITA value measurement: Use a skin colorimeter to measure the ITA value of the volunteers' skin before and after using the product, and record the changes every week. The ITA value (Individual Typology Angle) is an indicator used to evaluate skin brightness. The higher the value, the brighter the skin.

[0103] (2) ITA value measurement: Use a skin melanin index meter to measure the skin melanin index (MI) of volunteers before and after using the product, and record the weekly changes. The MI value is an indicator for evaluating the melanin content of the skin. The lower the value, the less melanin content.

[0104] (3) Visual skin color rating assessment: Professional dermatologists visually evaluate the skin color of volunteers before and after using the product, and record the changes every week. The visual skin color rating is divided into 1-5 levels, with 1 indicating the most even skin color and 5 indicating the most uneven skin color.
