[Abstract]
Using the results of a web-based questionnaire, the relationship between light environment and skin condition was investigated. By analyzing 2,200 women who staying in well-lit rooms during the day, it was found that presence of natural light from windows during the day and lighting color before bedtime were associated with skin condition. These results suggest that differences in light environment may have an effect on skin condition.
