Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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	Change from baseline skin moisture content	Skin moisture content is evaluated by using a Corneometer CM825®t	Week0, 2, 4, 8 and week 4 after the end of intake
Secondary	Change from baseline trans-epidermal water transpiration	Trans-epidermal water transpiration is evaluated by using Tewameter TM300®	Week0, 2, 4, 8 and week 4 after the end of intake
Secondary	Change from baseline VISIA image	Analyze the following items are measured and simply by putting face into VISIA Evolution.; Measurement points:Photograph the left face Analysis target value:Blemishes, Wrinkles, Texture. Pores, Ultraviolet Blemishes, Brown Blemishes, Red Areas, Porphyrin.Higher numbers for these items indicate more advanced aging.; Gloss is measured by VISIA-CR.	week 0, 2, 4, 8 and week 4 after the end of intake
Secondary	Change from baseline face visual evaluation	Face visual evaluation is measured by the dermatologist. Evaluation items:Cutaneous carpus, cutaneous groove, comprehensive evaluation Evaluation site:Evaluation centered on the left face, connecting the lower earlobe and the edge of the lip Evaluation method:Perform visual judgment using DermLite DL100 (J Hewitt Co., Ltd.) and microscope (KH-1300/HXG-2016Z/HIROX).; There are 5 levels of evaluation, and judgment is made using the following criteria.; -2 (Poor), -1 (Slightly Poor), 0 (Normal), 1 (Somewhat Good), 2 (Good) Time Frame: Week 0, 2, 4, 8 and week 4 after the end of intake	Week0, 2, 4, 8 and week 4 after the end of intake
