And (3) testing items:
(1) short term moisturization-skin moisture test
The sample double-layer mask of example 2 was uniformly mixed by stirring, and then, a single application was performed on the inner side of the forearm at an amount of (2.0 + -0.1) mg/CM2, and the sample double-layer mask of example 2 was uniformly applied in a uniform application test area, and the blank control group was used as a first group test, after the sample double-layer mask of example 2 was uniformly mixed by stirring, a single application was performed on the inner side of the forearm at an amount of (2.0 + -0.1) mg/CM2, and the sample double-layer mask of comparative example 1 was uniformly mixed by stirring, and then, a single application was performed on the inner side of the forearm at an amount of (2.0 + -0.1) mg/CM2, and the uniform application test area was used as a second group test, and then, a skin moisture tester (german corneometer 825 CM) was used for 15min, 30min, 1h, and the test area was uniformly applied, The moisture content of the skin was measured in the left and right forearm medial test areas at 1.5h, 2h, with specific results as in tables 2 and 3, and fig. 1 is a bar graph of the change in moisture content of the forearm medial using the sample of example 2.
TABLE 2 subjects at a first set of different time points forearm medial stratum corneum moisture content (x. + -.s)
TABLE 3 moisture content of forearm medial stratum corneum of subjects at a second different time point (x. + -. s)
The skin moisture meter Corneometer CM825 is used for detecting the moisture content of the skin stratum corneum, and the higher the moisture content measurement value of the skin stratum corneum is, the higher the moisture content of the skin stratum corneum is. As can be seen from the data in Table 2, the data differences between the moisture content variation of the horny layer of the inner forearm skin of the group of example 2 and the moisture content variation of the skin before use in 15min, 30min, 1h, 1.5h, and 2h, the data differences between the moisture content variation of the horny layer of the inner forearm skin of the group of example 2 and the moisture content variation of the skin before use all have statistical significance (P <0.05), the moisture content of the whole skin is in an increasing trend, the data differences between the moisture content variation of the horny layer of the inner forearm skin of the group of blank control and the moisture content variation of the skin before use in 15min, 30min, 1h, 1.5h, and 2h, the data differences between the moisture content variation of the horny layer of the inner forearm skin of the group of comparative example 1 and the moisture content variation of the skin before use in 15min, 30min, 1h, 1.5h, and 2h, the values of the measured values of the two groups of the example 2 group and the blank control group are compared with the initial values at 15min, 30min, 1h, 1.5h and 2h, the data have significant difference (P <0.05), and the values of the measured values of the two groups of the example 2 group and the comparative example 1 group are compared with the initial values at 15min, 30min, 1h, 1.5h and 2h, the data have significant difference (P < 0.05). Experimental data show that the difference value between the measured value and the initial value of 15min, 30min, 1h, 1.5h and 2h of the example 2 is obviously improved and the moisturizing effect is obvious compared with a blank control group, the difference value between the measured value and the initial value of 15min, 30min, 1h, 1.5h and 2h of the example 2 is larger than that of the comparative example 2 group, and the moisturizing effect of the example 2 is better, namely, the double-layer mask provided by the invention has the effect of quickly improving the moisture content of the skin in a short period, and particularly when betaine, allantoin and shea butter are used together in a specific proportion and dosage, the skin moisturizing content can be obviously improved.
(2) Long-term moisturization-skin moisture test
After cleaning, the double-layer facial masks of example 2 and comparative example 1 were torn off the aluminum foil paper, stirred and mixed uniformly, and applied to the left and right cheeks of the subject, respectively, and after 15min of static application, the facial masks were washed with clean water, and used 3 times per week for 2 weeks, and the moisture content of the stratum corneum of the cheekbone skin of the left and right cheeks was measured by a skin moisture tester (german CKCorneometer CM825) for 1 week and 2 weeks before use, and the specific results are shown in table 4.
TABLE 4 subjects the facial test area stratum corneum moisture content (x + -s) at various time points
The skin moisture meter Corneometer CM825 is used for detecting the moisture content of the skin stratum corneum, and the higher the moisture content measurement value of the skin stratum corneum is, the higher the moisture content of the skin stratum corneum is. As can be seen from the data in table 4, the data for example 2 compared the facial moisture content at D7, D14 to before use was statistically significant (P <0.05), and for comparative example 1 compared the facial moisture content at D7 to before use, the data was not statistically significant (P > 0.05); comparative example 1 the data was statistically significant (P <0.05) when the facial moisture content of D14 was compared to that before use; the difference between the measured value and the initial value of the two groups of example 2 and comparative example 1 was compared at D7 and D14, and the data were significantly different (P < 0.05). Experimental data show that the double-layer mask provided by the invention can achieve a better moisturizing effect in a shorter time, has a better long-term moisturizing effect, has an effect of improving the water content of skin for a long time, and has a good moisturizing effect.
And (3) summarizing the effects: as can be seen from the effect comparison between the example 2 and the comparative example 1, the comparative example 1 has certain short-term water replenishing and long-term water replenishing effects under the condition of lacking certain specific components, but the effect is not obvious, which indicates that the obvious water replenishing effect of the double-layer mask provided by the invention is generated by the synergistic effect of different components in the formula, and the double-layer mask has obvious water replenishing and moisturizing effects under the conditions of specific component selection, specific proportion and dosage range, that is, the double-layer mask provided by the invention has good comprehensive water replenishing and moisturizing effects of instant water replenishing and long-term water replenishing, so that the skin is tender and transparent and full of vitality, the effects of rapidly replenishing water and revitalizing the skin can be achieved, and the higher skin care requirements of people can be met.
(4) Subject self-assessment
All subjects were subjected to a questionnaire, which is a subjective evaluation of the subjects on the use of the product of example 2, and the main evaluation items were: the skin is not sensitive and not easy to be reddened, the face has fine lines, the skin has moist feeling, the skin color brightness, the skin fineness, the skin smoothness and the like, and the specific results are shown in figure 2.
As can be seen from fig. 2, the results of the volunteers self-evaluation after 14 days of use of the bilayer mask were: 100% of subjects think that the skin is not sensitive and not easily reddened after using the double-anti-small-muscle-egg mask for 14 days, the skin becomes smoother and glossy, the fine wrinkles on the face are reduced and finer, the skin moisture is increased, and the subjects think that the skin is not sensitive and not easily reddened improves by 74%; facial fine lines are reduced by 66%; the skin has 76% of moisturizing effect; skin color brightening 66%; the skin fineness is improved by 70%; the smoothness of the skin was improved by 70%. Meanwhile, the satisfaction of the subjects on the skin improvement using the double-layer mask was 100%.
