470 A study of skin characteristics according to humidity during sleep

During sleep, the skin is exposed to various environments for example low or high humidity and the average of 7 to 8 hours of sleeping in those situations can affect skin condition. Therefore, the objective of this study is to determine skin characteristics according to humidity during sleep. Eleven healthy women in their ages of 20s and 30s were controlled.
