Abstract
The purpose of this study was to examine the consumer's own classification of skin type in terms “oily skin” or “dry skin” and to compare it with the data obtained by instrumental measurments of subject's skin characteristics.
For this purpose. we measured the sebumquantity, surface topography, skin pH, transepidermal water loss and buffering capacity of the forehead skin of 500 females using various instrumental methods. Questionaires were given to the subjects to survey their own classification of the skin type.
The results of this survey, as the objectively mesured data, were statistiically analyzed.
It was found that there was a definite relationship between the skin type, sebum quantity and skin roughness.
