Figure 1

Graphic illustration representing the percentage of skin modification (∂ reduction) according to the observers (A,B,C) and the 3D SPM readouts (the highest ∂ reduction and roughness ∂ reduction in the total sample, and the simultaneous computation of RghDS ∂ reduction plus VDS ∂ reduction in group DS, and RghR ∂ reduction plus ADR ∂ reduction in group R).
