3. Color shade test of color spots
All of the above examples and comparative examples containing anti-blue light repair compositionsThe emulsions prepared in the examples were subjected to a human skin color test using a skin color tester VISIA-CR (Canfield, USA) by the following method: each group of 15 healthy women aged 18-40 years old, and each group of anti-blue light repairing lotion was taken to be equal (2 mg/cm) 2 ) Applying on left and right faces, drying after 10min absorption, and using LED blue light 475nm (3 mW/cm) 2 Lasting 30 min) irradiating the face of the test subject for 30min, once in the morning and once in the evening, respectively using a skin color tester VISIA-CR to take pictures of the OD values of the parameters of the color depth of the color spot of the face of the test area before the sample is applied and after the sample is used for four weeks, using a VISIA software to analyze the OD values of the test area at 0 week and 4 week, carrying out parallel tests for 3 times, taking the average value, and recording the OD value.
The change rate is relative to the change rate before use, and the calculation formula is as follows:
delta (difference) = K after four weeks 4 -K 0
In the formula, K 0 -OD value before cosmetic application in the test area.
K 4 OD after four weeks of application of the cosmetic in the test area.
N-number of subjects.
The test results are shown in Table 6, and the smaller the OD value of the shade parameter of the stain color, the darker the skin. The comparative example is obviously different from the example, and the anti-blue light repair composition can effectively relieve the generation of skin stains caused by blue light, while the example 1 has the best effect.
TABLE 6
4. Changes in skin elasticity
All of the above-described emulsions prepared in the examples and comparative examples containing the blue-light-resistant repair composition were subjected to a human skin elasticity test using a skin elasticity tester (current dual MPA 580) according to the following test methods: each group selected 15 healthy women, aged 18-40 years, applied with samples on the cheeks, once in the morning and evening, and during the product using period, the skin elasticity test was performed with an instrument for 3 times of parallel tests before the samples were applied and after the samples were used for four weeks, with the average facing screen blue light (mobile phone, computer, tablet computer) every day.
Wherein, the change rate is relative to the change rate before use, and the calculation formula is as follows:
delta (difference) = T after four weeks 4 -T 0
In the formula, T 0 -the pre-cosmetic R2 value of the test area.
T 4 R2 value after four weeks of makeup application in the test area.
N-number of subjects.
The test results are shown in Table 7, and the closer the R2 value of the skin elasticity is to 1, the better the skin elasticity is. The higher the rate of change of R2 value, the better the effect of the sample in increasing skin elasticity. The comparative example is obviously different from the example 1, and meanwhile, the blue light resistant repair composition has a better effect of improving the skin elasticity.
TABLE 7
5. Skin texture change
All emulsions prepared in the examples and comparative examples containing the blue-light-resistant repair composition are subjected to human skin texture value testing, a testing instrument is a skin rapid optical imaging analysis system Derma TOP, and corresponding software is applied to analyze the arithmetic average roughness Ra value of the skin. The test method comprises the following steps: each group selected 15 healthy women aged 18-40 years, with samples applied to the cheeks, once in the morning and evening, and during use of the product, the women should face an average of 4 hours of blue light on the screen (mobile phone, computer, tablet computer) per day. The skin elasticity test was performed with the instrument before application of the sample and after four weeks use, 3 times in parallel, the average was taken and the Ra value was recorded.
Wherein, the change rate is relative to the change rate before use, and the calculation formula is as follows:
Δ (difference) = M after four weeks 4 -M 0
In the formula, M 0 -pre-cosmetic Ra value for the test area.
M 4 Ra values after four weeks of application of the cosmetic to the test area.
N-number of subjects.
The test results are shown in Table 8, wherein the Ra value represents the arithmetic average roughness of the skin, the lower the value, the lower the texture degree of the skin, and the lower the change rate of the Ra value, and the better the effect of lightening the fine lines of the skin of the sample. The comparative example is obviously different from the example 1, and meanwhile, the blue light resistant repair composition disclosed by the invention effectively relieves the skin photoaging phenomenon caused by blue light, so that the skin keeps tight and elastic.
TABLE 8
The invention has many applications, and the above description is only a preferred embodiment of the invention. It should be noted that the above examples are only for illustrating the present invention, and are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that various modifications can be made without departing from the principles of the invention and these modifications are to be considered within the scope of the invention.
