This is a survey to observe the skin property of healthy women in her 20s. The subjects are divided 2 groups different about the amount of cumulative light exposure. Furthermore, it investigates the relation with the actual feeling and consciousness.

Measurements were performed in the high and low UV exposure groups. As a result, it was confirmed that there were significant differences in pore area, stratum corneum water content, intercellular lipid structure, etc. between the groups. It was also found that there is a difference between the groups about ultraweak photon emission.
From these results, it was suggested that skin changes caused by photoaging can be evaluated by these measurements.
