The aim of this study was to compare the biophysical properties of different facial zones.
We investigated transepidermal water loss (TEWL), skin temperature and sebum casual level (CL) on 90 adjacent test sites distributed on the forehead, cheeks and chin of five women.
All three parameters showed a symmetrical distribution around the facial median line. Only minor variations of individual values were found within the forehead and the chin areas. In contrast, the cheeks exhibited a distinct gradient with highest values in the paranasal zones and lowest on the cheek bones for all of the three parameters. The mean values on both cheeks of a given individual were nearly identical, and the patterns within the two cheeks were superimposable. Both CL and skin temperature distributions pointed out a "T-zone" with highest values on the forehead, on the chin and on the median part of the cheek.
Our data demonstrate that biophysical skin properties differ considerably between different facial areas but that they follow a characteristic distribution.
