Transepidermal water loss, temperature and sebum levels on women's facial skin follow characteristic patterns.
2000
Background/aims: The aim of this study was to compare the biophysical properties of different facial zones.
Methods: 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.
Results: 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.
Conclusions: Our data demonstrate that biophysical skin properties differ considerably between different facial areas but that they follow a characteristic distribution.
