3.7 Conclusions

根据数据分析结果，试验期间水光针治疗对照样品组和非水光针治疗JC测试样品组受试者在任一访视时间点，皮肤角质层含水量测量值显著高于使用前基础值，则可认为水光针治疗和JC测试样品均具有保湿功效。若非水光针治疗JC测试样品组皮肤角质层含水量测量值与水光针治疗对照样品组比较无差异，则可认为JC测试样品对皮肤的保湿功效与水光针治疗相当；若显著高于水光针治疗对照样品组，则可认为JC测试样品对皮肤的保湿功效优于水光针治疗；若显著低于水光针治疗对照样品组，则可认为测试样品对皮肤的保湿功效不及水光针治疗。
According to the results of data analysis, the measured water content of the stratum corneum of the skin in the control sample group and the non-skinbooster treatment JC test sample group during the trial period was significantly higher than the basic value before use, which can be considered to have moisturizing effect of both the skin booster treatment and the JC test sample. If there is no difference in the measurement of water content in the stratum corneum of the non-skinbooster treatment JC test group compared with the control sample group, it can be considered that the moisturizing effect of the JC test sample on the skin is comparable to that of the skinbooster treatment. If it is significantly higher than that of the control sample group of skin booster treatment, it can be considered that the moisturizing effect of the JC test sample on the skin is better than that of the skin booster treatment. If it is significantly lower than that of the control sample group, it can be considered that the moisturizing effect of the test sample on the skin is not as good as that of the skin booster treatment.

根据数据分析结果，试验期间水光针治疗对照样品组和非水光针治疗JC测试样品组受试者在任一访视时间点，皮肤弹性评估参数测量值显著高于使用前基础值，则可认为水光针治疗和JC测试样品均具有提升皮肤弹性的功效。若非水光针治疗JC测试样品组皮肤弹性评估参数测量值（或与使用前基础值的变化率）与水光针治疗对照样品组测量值（或与使用前基础值的变化率）比较无差异，则可认为JC测试样品对皮肤弹性提升的效果与水光针治疗相当；若显著高于水光针治疗对照样品组，则可认为JC测试样品对皮肤弹性提升的效果优于水光针治疗；若显著低于水光针治疗对照样品组，则可认为JC测试样品对皮肤弹性提升的效果不及水光针治疗。
According to the results of data analysis, during the trial, the measured values of skin elasticity evaluation parameters in the control sample group and the non-skinbooster treatment JC test sample group were significantly higher than the basic values before use, which can be considered to have the effect of improving skin elasticity in both the skin booster treatment and the JC test samples. If there is no difference between the measured values of skin elasticity assessment parameters (or the rate of change from the basal value before use) of the non-skinbooster treatment sample group and the measurement (or the rate of change from the basal value before use) of the control sample group of the skinbooster treatment, it can be considered that the effect of the JC test sample on the improvement of skin elasticity is comparable to that of the skinbooster treatment. If it was significantly higher than that of the control sample group of skin booster treatment, it could be considered that the effect of JC test sample on skin elasticity improvement was better than that of skin booster treatment. If it is significantly lower than that of the control sample group of skin booster treatment, it can be considered that the effect of JC test sample on skin elasticity improvement is not as good as that of skin booster treatment.

根据数据分析结果，试验期间水光针治疗对照样品组和非水光针治疗JC测试样品组受试者在任一访视时间点，皮肤紧实度评估参数测量值与使用前基础值比较显著降低，则可认为水光针治疗和JC测试样品均具有提升皮肤紧实度的功效。若非水光针治疗JC测试样品组皮肤紧实度评估参数测量值（或与使用前基础值的变化率）与水光针治疗对照样品组（或与使用前基础值的变化率）比较无差异，则可认为JC测试样品对皮肤紧实度提升的效果与水光针治疗相当；若显著低于水光针治疗对照样品组，则可认为JC测试样品对皮肤紧实度提升的效果优于水光针治疗；若显著高于水光针治疗对照样品组，则可认为JC测试样品对皮肤紧实度提升的效果不及水光针治疗。
According to the results of data analysis, during the trial, the measured values of skin firmness evaluation parameters in the control sample group and the non-skinbooster treatment JC test sample group were significantly lower than the basic values before use, which can be considered to have the effect of improving skin firmness. If there is no difference between the measurement of skin firmness evaluation parameters (or the rate of change from the basal value before use) in the non-skinbooster treatment JC test group and the control sample group (or the rate of change from the basal value before use), it can be considered that the effect of the JC test sample on skin firmness improvement is comparable to that of the skinbooster treatment. If it was significantly lower than that of the control sample group of skin booster treatment, it can be considered that the effect of JC test sample on skin firmness improvement is better than that of skin booster treatment.

根据数据分析结果，试验期间水光针治疗对照样品组和非水光针治疗JC测试样品组受试者在任一访视时间点，皮肤皱纹评估参数测量值与使用前基础值比较显著降低，则可认为水光针治疗和JC测试样品均具有改善皮肤皱纹的功效。若JC测试样品侧皮肤皱纹评估参数测量值（或与使用前基础值的变化率）与水光针治疗对照样品组（或与使用前基础值的变化率）比较无差异，则可认为JC测试样品改善皮肤皱纹的效果与水光针治疗相当；若显著低于水光针治疗对照样品组，则可认为JC测试样品改善皮肤皱纹的效果优于水光针治疗；若显著高于水光针治疗对照样品组，则可认为JC测试样品改善皮肤皱纹的效果不及水光针治疗。
According to the results of data analysis, during the trial, the measured values of skin wrinkle evaluation parameters in the control sample group and the non-skinbooster treatment JC test sample group were significantly lower than the basic values before use, and it can be considered that both the skin wrinkle treatment and the JC test samples have the effect of improving skin wrinkles. If there is no difference between the measured value of the skin wrinkle assessment parameter on the side of the JC test sample (or the rate of change from the base value before use) and the control sample group (or the rate of change from the base value before use), the effect of the JC test sample in improving skin wrinkles is considered to be comparable to that of skin booster treatment. If it was significantly lower than that of the control sample group of skin booster treatment, it can be considered that the effect of JC test sample in improving skin wrinkles is better than that of skin booster treatment. If it is significantly higher than that of the control sample group of skin booster treatment, it can be considered that the effect of JC test sample in improving skin wrinkles is not as good as that of skin booster treatment.

根据数据分析结果，试验期间水光针治疗对照样品组和非水光针治疗JC测试样品组受试者在任一访视时间点，皮肤光泽度测量值与使用前基础值比较显著升高，则可认为水光针治疗和JC测试样品均具有提升皮肤光泽度的效果。若JC测试样品侧皮肤光泽度测量值（或与使用前基础值的变化率）与水光针治疗对照样品组（或与使用前基础值的变化率）无差异，则可认为JC测试样品改善皮肤光泽度的效果与水光针治疗相当；若显著高于水光针治疗对照样品组，则可认为JC测试样品改善皮肤光泽度的效果优于水光针治疗；若显著低于水光针治疗对照样品组，则可认为JC测试样品改善皮肤光泽度的效果不及水光针治疗。
According to the results of data analysis, the skin radiance measurement value of the control sample group and the non-skinbooster treatment JC test sample group during the trial period was significantly higher than the basic value before use, which can be considered to have the effect of improving skin radiance in both the skin booster treatment and the JC test sample. If there is no difference between the measured skin radiance (or the rate of change from the basal value before use) on the side of the JC test sample and the control sample group (or the rate of change from the basal value before use), the effect of the JC test sample in improving skin radiance is considered to be comparable to that of the skinbooster treatment; If it was significantly higher than that of the control sample group of skin booster treatment, it could be considered that the effect of JC test sample in improving skin radiance was better than that of skin booster treatment. If it is significantly lower than that of the control sample group of skin booster treatment, it can be considered that the effect of JC test sample on improving skin radiance is not as good as that of skin booster treatment.

根据数据分析结果，试验期间水光针治疗对照样品组和非水光针治疗JC测试样品组受试者在任一访视时间点，皮肤粗糙度评估参数测量值与使用前基础值比较显著降低，则可认为水光针治疗和JC测试样品均具有改善皮肤粗糙度的效果。若JC测试样品侧皮肤粗糙度测量值（或与使用前基础值的变化率）与水光针治疗对照样品组比较无差异，则可认为JC测试样品改善皮肤粗糙度的效果与水光针治疗相当；若显著低于水光针治疗对照样品组，则可认为JC测试样品改善皮肤粗糙度的效果优于水光针治疗；若显著高于水光针治疗对照样品组，则可认为JC测试样品改善皮肤粗糙度的效果不及水光针治疗。
According to the results of data analysis, the measured values of skin roughness evaluation parameters in the control sample group and the non-skinbooster treatment JC test sample group during the trial period were significantly lower than the basic values before use, which can be considered to have the effect of improving skin roughness in both the skin skin booster treatment and the JC test samples. If there is no difference between the measured skin roughness of the JC test sample (or the rate of change from the basal value before use) and the control sample group of the skin booster treatment, it can be considered that the improvement effect of the JC test sample is comparable to that of the skin booster treatment. If it was significantly lower than that of the control sample group of skin booster treatment, it can be considered that the effect of JC test sample in improving skin roughness is better than that of skin booster treatment. If it was significantly higher than that of the control sample group, it can be considered that the effect of the JC test sample in improving skin roughness is not as good as that of the skin booster treatment.

角质层含水量
Moisture content of the stratum corneum

皮肤角质层含水量通过CK Corneometer CM825测定，测量值越大，表明测试部位皮肤角质层含水量越高。本项目在使用前/治疗前、第7天、第14天、第28天及第56天访视时分别测定各组受试者同一测试区域皮肤角质层含水量，通过对比测量值的变化来评估
The water content of the stratum corneum of the skin was determined by the CK Corneometer CM825, and the larger the measurement, the higher the water content of the stratum corneum of the skin at the test site.

There was no significant difference between the measured moisture content of the stratum corneum in the D0 test area before the use of the test samples in the non-skinbooster treatment JC test group and the pre-treatment measurement in the control sample group (P>0.05).

在第7天访视时，非水光针治疗JC测试样品组受试者测试区域皮肤角质层含水量测量值与使用前基础值比较升高，差异具有极显著性（P<0.001）；水光针治疗对照样品组受试者测试区域皮肤角质层含水量测量值与治疗前基础值比较升高，差异具有极显著性（P<0.001）；非水光针治疗JC测试样品组角质层含水量测量值低于水光针治疗对照样品组，差异具有显著性（P<0.05）；非水光针治疗JC测试样品组测量值与使用前基础值的变化率低于水光针治疗对照样品组，差异具有极显著性（P<0.001）。由此提示，在该研究条件下，JC测试样品使用7天与水光针治疗后7天对受试者测试部位皮肤均具有保湿功效，水光针治疗对受试者测试部位皮肤保湿功效优于JC测试样品。
At the 7th day visit, the measured water content of the stratum corneum in the test area of the subjects in the JC test group was significantly higher than that before the use (P<0.001). Compared with the basic value before treatment, the measured water content of the stratum corneum in the test area of the control group was significantly different from that before treatment (P<0.001). The measurement of stratum corneum water content in the non-skinbooster JC test group was lower than that in the control group, and the difference was significant (P<0.05). The change rate between the measured value and the basal value before use in the non-skinbooster treatment JC test group was lower than that in the control group, and the difference was extremely significant (P<0.001). The results suggest that under the study conditions, the JC test samples had moisturizing effect on the skin of the test site after 7 days of use and 7 days after the treatment with skin boosters, and the moisturizing effect of the skin treatment on the test site of the subjects was better than that of the JC test samples.

At the 14-day visit, the measured water content of the stratum corneum in the test area of the subjects in the non-skin skin treatment JC test group was higher than the basal value before use, and the difference was extremely significant (P<0.001). The measurement of stratum corneum water content in the test area of the control group was significantly higher than that before treatment (P<0.001), while there was no significant difference between the measurement of stratum corneum water content in the non-skinbooster treatment JC test group and the control sample group (P>0.05). The change rate between the measured value and the basal value before use in the non-skinbooster treatment JC test group was lower than that in the control group, and the difference was significant (P<0.05). The results suggest that under the study conditions, the JC test samples had moisturizing effect on the skin of the test site after 14 days of use and 14 days after the treatment of skin boosters, and the moisturizing effect of skin booster treatment on the skin of the test site was better than that of the JC test samples.

在第28天访视时，非水光针治疗JC测试样品组受试者测试区域皮肤角质层含水量测量值与使用前基础值比较升高，差异具有极显著性（P<0.001）；水光针治疗对照样品组受试者测试区域皮肤角质层含水量测量值与治疗前基础值比较升高，差异具有极显著性（P<0.001）；非水光针治疗JC测试样品组D₂₈测量值与水光针治疗对照样品组比较无明显差异（P>0.05）；非水光针治疗JC测试样品组D₂₈测量值与使用前基础值的变化率与水光针治疗对照样品组比较无明显差异（P>0.05）。由此提示，在该研究条件下，JC测试样品使用28天与水光针治疗后28天对受试者测试部位皮肤均具有保湿功效，JC测试样品对受试者测试部位皮肤保湿功效与水光针治疗相当。
At the 28-day visit, the measured water content of the stratum corneum in the test area of the subjects in the non-skin light injection treatment JC test group was higher than the basal value before use, and the difference was extremely significant (P<0.001). The measurement of water content in the stratum corneum of the test area of the subjects in the control group was significantly higher than that before treatment (P<0.001), and there was no significant difference between the D28 measurement in the non-skinbooster treatment JC test group and the control group (P>0.05). There was no significant difference between the D28 measurement value and the basal value before use in the non-skinbooster treatment JC test group and the control sample group (P>0.05). It was suggested that under the study conditions, the JC test samples had moisturizing effect on the skin of the test site for 28 days and 28 days after the skin booster treatment, and the moisturizing effect of the JC test sample on the skin of the test site was comparable to that of the skin of the skin of the subject under the treatment of skin boosters.

在第56天访视时，非水光针治疗JC测试样品组受试者测试区域皮肤角质层含水量测量值与使用前基础值比较升高，差异具有极显著性（P<0.001）；水光针治疗对照样品组受试者测试区域皮肤角质层含水量测量值与治疗前基础值比较升高，差异具有极显著性（P<0.001）；非水光针治疗JC测试样品组D₅₆测量值与水光针治疗对照样品组比较无明显差异（P>0.05）；非水光针治疗JC测试样品组D₅₆测量值与使用前基础值的变化率与水光针治疗对照样品组比较无明显差异（P>0.05）。由此提示，在该研究条件下，JC测试样品使用56天与水光针治疗后56天对受试者测试部位皮肤均具有保湿功效，JC测试样品对受试者测试部位皮肤保湿功效与水光针治疗相当。
At the 56-day visit, the measured water content of the stratum corneum in the test area of the subjects in the non-skin light injection treatment JC test group was higher than the basal value before use, and the difference was extremely significant (P<0.001). Compared with the basic value before treatment, the measured value of stratum corneum in the test area of the control group was significantly different (P<0.001), while there was no significant difference between the D56 value of the non-skinbooster treatment JC test group and the control group (P>0.05). There was no significant difference between the measured value of D56 and the basal value before use in the non-skinbooster treatment JC test group and the control sample group (P>0.05). This suggests that under the study conditions, the JC test samples had moisturizing effect on the skin of the test site for 56 days and 56 days after the skin booster treatment, and the moisturizing effect of the JC test sample on the skin of the test site was comparable to that of the skin booster treatment.

经表皮水分流失
Transepidermal water loss

经表皮水分流失是指单位时间内测试部位皮肤水分蒸发速率，可间接反应表皮通透屏障功能，测量值越低，表明测试部位皮肤单位时间内经表皮水分流失越少，间接反应表皮通透屏障功能越好。敏感性皮肤该数值常增高。本项目在使用前/治疗前、第7天、第14天、第28天及第56天分别测定各组受试者同一测试区域皮肤经表皮水分流失，通过对比两组测量值的变化来评估水光针治疗对照样品及非水光针治疗JC测试样品对测试区域皮肤经表皮水分流失的影响。
Transepidermal water loss refers to the rate of skin water evaporation per unit time of the test site, which can indirectly reflect the epidermal permeable barrier function, and the lower the measured value, the lower the transepidermal water loss of the skin at the test site per unit time, and the better the indirect reaction epidermal permeable barrier function. This is often elevated in sensitive skin. In this study, the transepidermal water loss of the same test area was measured by the subjects in each group before use/treatment, day 7, day 14, day 28 and day 56, and the effect of skin transepidermal water loss in the test area was evaluated by comparing the changes of the measured values between the two groups.

The change rate between the measured value and the basal value before use in the non-skinbooster treatment JC test group was lower than that in the control group, and the difference was statistically significant (P<0.05).

There was no significant difference in the rate of change between the measured value of D14 and the basal value before use in the non-skinbooster treatment JC test group compared with the control sample group (P>0.05).

The change rate of D28 measurement and the basal value before use in the non-skinbooster treatment JC test group was lower than that in the control group, and the difference was statistically significant (P<0.05). This suggests that under the study conditions, the JC test sample used for 56 days has a repair effect on the skin barrier function of the subject's test site.

光泽度
Glossiness

通过SkinGlossMeter测量皮肤表面镜面反射回来的光，可反映测试区域皮肤表面对光的反射能力，反射光强度越大则测量值越大，表征皮肤表面越有光泽，反之则皮肤越晦暗。本项目在使用前/治疗前、第7天、第14天、第28天及第56天分别测定各组受试者同一测试区域皮肤光泽度，通过对比两组测量值的变化来评估水光针治疗对照样品及非水光针治疗JC测试样品对测试区域皮肤光泽度的影响。
The greater the intensity of the reflected light, the greater the measured value, the more shiny the skin surface, and the darker the skin. In this study, the skin gloss of the same test area was measured in each group before use/treatment, day 7, day 14, day 28 and day 56, and the effect of skin radiance on the skin radiance of the test area was evaluated by comparing the changes of the measured values between the two groups.

肤的回弹量和有负压时的最大拉伸值之比，它越接近1，弹性越好；R5值是皮肤测试的第一次循环中，皮肤恢复过程的弹性部分与加负压过程的弹性部分之比，越接近1，说明皮肤弹性越好；R7值是皮肤测试过程的第一次循环中，皮肤恢复过程的弹性部分与这次循环过程中皮肤的最大拉伸量之比，越接近1，说明皮肤弹性越好；Q1值是在皮肤测试的第一次循环中，皮肤恢复过程的弹性部分的面积加上皮肤恢复过程的塑性部分的面积与第一次负压时皮肤被拉伸的最大幅度的面积之比，比值越接近1，弹性越好。本项目在使用前/治疗前、第7天、第14天、第28天及第56天分别测定各组受试者同一区域皮肤弹性评估参数，通过对比两组测量值的变化来评估水光针治疗对照样品及非水光针治疗JC测试样品对测试区域皮肤弹性的影响。
The ratio of the rebound amount of the skin to the maximum tensile value when there is negative pressure, the closer it is to 1, the better the elasticity; The R5 value is the ratio of the elastic part of the skin recovery process to the elastic part of the negative pressure process in the first cycle of the skin test, the closer to 1, the better the skin elasticity; The R7 value is the ratio of the elastic part of the skin recovery process to the maximum stretch of the skin during this cycle in the first cycle of the skin testing process, the closer to 1, the better the skin elasticity; The Q1 value is the ratio of the area of the elastic part of the skin recovery process plus the area of the plastic part of the skin recovery process to the area of the maximum amplitude of the skin stretching during the first negative pressure in the first cycle of the skin test, the closer the ratio is to 1, the better the elasticity. In this project, the skin elasticity assessment parameters of the subjects in the same area were measured before use/treatment, day 7, day 14, day 28 and day 56, and the effects of skin elasticity in the test area were evaluated by comparing the changes of the measured values of the two groups.
