Abstract
In considering the effect of cosmetics, the moisturizing effect on the skin is most important.
This consists of two components, one being the occlusivity which suppress water evaporation, and the other is water holding capacity. A new method for measuring the water evaporation rate (WER) has been developed by us. The present study was carried out in order to clarify the following: 1) The relationship between WER through the skin and skin condition. 2) The factors which determine occlusivity. In conclusion, it was recognized that the morphology of the skin surface become fine with decreasing WER and it was clarified that occlusivity could be explained in terms of lnorganic organic balance (10B), visvosity and water holding capacity.
