20대 여성의 피부 수분량의 계절에 의한 변화 - 한일비교

A study on seasonal changes of skin hydration in women in their 20"s -Comparison of Korean and Japanese-

&nbsp;&nbsp;The purpose of this study was to examine the skin hydration and life style of Japanese and Korean women. I used a Moisture Checker to measure the hydration status of 2 facial spots, on forehead and cheek of the face, and on the upper arm in each of the seasons. The result were analyzed by using a three-factor(nationality, site and season) analysis of variance(3-way ANOVA) and post hoc analysis were performed using a Fisher&quot;s PLSD multiple-comparison test.<BR>&nbsp;&nbsp;The result were as follows: 1) The Japanese showed a higher hydration than the Korean women in spring and a lower hydration in summer on their faces. On the seasonal changes, there was a significant difference between Japanese and Korean women on their faces. The Japanese showed significantly higher hydration in fall than in other seasons. On the other hand, Koreans showed hugher hydration in summer and lower hydration in spring. 2) The Japanese women showed a lower hydration than the Korean s in fall and winter on their arm. On the seasonal changes, there was no significant difference between the Japanese and Korean women. Both the Japanese and Korean women showed the highest hydration in summer and the lowest hydration in winter.
