Abstract
It has been shown that the skin moisture content has an annual fluctuation characteristic, being high in the summer and low in the winter. Similarly, the fineness of skin texture might also have annual fluctuation characteristics. On the other hand, in order to clarify annual changes in skin moisture content and texture, it is necessary to understand the effects of skin wetting with short period in daily activities such as washing hands and bathing on the annual fluctuation. In this study, in order to investigate the effect of skin wetting on subsequent changes in moisture content, the moisture content of the skin was measured over time before and after the 5 or 10 minutes of immersion in water and wiping off the water from the surface. The measured results show that the skin moisture content, which increased due to wetness, rapidly decreased with the start of the exposure to the air, and the skin moisture content converged to a constant value, which was close to the skin moisture content before immersion in water, approximately within 15 to 25 minutes when immersed for 5 minutes and within 30 to 40 minutes when immersed for 10 minutes.
