Difference between the biologic and chronologic age as an individualized indicator for the skin care intensity selection: skin topography and immune system state studies, parameter correlations with age difference

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
