The transepidermal water loss (TWL) was measured on healthy adults using the electrohygrometric method.
TWL value was significantly higher in 20-24 ages than in 25-50 ages. The relationship between TWL value and ambient conditions seemed to vary exponentially. The occlusive nature of petrolatum decreased with raising temperature and relative humidity.
These results showed availabilities of our original method for TWL in cosmetological research.
