We examined the seasonal changes in water content of stratum corneum, skin surface temperature, and transepidermal water loss of forearm skin. Water content of stratum corneum and skin surface temperature were significantly lower (P<0.01) in winter (room temperature 21℃) than in summer (room temperature 25℃), although transepidermal water loss was not different. By increasing room temperature to 25℃ in winter, skin surface temperature and transepidermal water loss were increased, whereas water content of stratum corneum was kept unchanged. Thus it is likely that water content of stratum corneum was influenced by seasonal adaptation rather than a short-term change in room temperature.
