Table 2 Correlation between skin roughness parameters and age difference BA – CA
Skin roughness parameter (calculated by the Cutometer embedded software) | BA – CA |
|---|---|
Sa, average roughness | − 0.381* |
Smax, maximum stretching of the roughness profile (difference between the highest “peak” and the deepest “valley” within the whole measured area) | − 0.194 |
Sz, ten-point height (average value of 5 highest peaks minus average value of 5 deepest valleys within the whole measured area) | − 0.278 |
Sp, height of the greatest profile peak | − 0.268 |
Sv, depth of the deepest profile valley | 0.413** |
Sda, mean dale area (average value of the local profile slope in the measured plane) | − 0.269 |
