Outcome Measures
Primary Outcomes (1)
Change from baseline skin viscoelasticity
In skin viscoelasticity measurement using Cutometer MPA580®, skin displacement is measured by applying negative pressure to the skin through the opening of the probe and releasing the negative pressure. The higher the value, the greater the viscoelasticity. Measurement part:Measure the center of the left face, connecting the bottom of the earlobe and the edge of the lip. Accepted value:Measure the same place 5 times, and use the average of 3 measurements with the highest and lowest value data removed based on the R2 value. Analysis target value:R0, R2, R5, R7
Week0, 2, 4, 8 and week 4 after the end of intake
Secondary Outcomes (4)
Change from baseline skin moisture content
Week0, 2, 4, 8 and week 4 after the end of intake
Change from baseline trans-epidermal water transpiration
Week0, 2, 4, 8 and week 4 after the end of intake
Change from baseline VISIA image
week 0, 2, 4, 8 and week 4 after the end of intake
