4.2.2 Performances of AEVA‐HE versus DermaTOP in study 2 When focusing on the crow's feet region extracted from both systems, using the same region of interest dimensions, comparable and highly significant results are obtained (Figures 12 , 13 ). “Sa” roughness parameter, ( r = 0.88) and for mean depth parameter ( R = 0.93) with p < 0.000001 in both cases.
