Abstract
This study concerns with the variation of transepidermal water loss when emollients are applied to the human skin.
Our experimental results; The effect of decreasing transepidermal water loss depends on thickness and properties of remaining film on the skin after applying cosmetic creams. Moreover, this effect correlates with the feeling of the film after applicaion, that is, the degree of “oiliness” by sensory test of creams.
We developed in vitro method which gave good correlation with in vivo method and confirmed these effects.
