Ultrasonographic subepidermal low‐echogenic band, dependence of age and body site

Background/purpose: The presence of an age‐dependent subepidermal low‐echogenic band (SLEB) is well established at specific body sites. Several studies have also proposed it to be a marker of photoaging, but only few studies have included children in their material, and UVR exposure has predominantly been evaluated as differences between body sites with different UVR exposure. The aim of this study was to further investigate the existence of SLEB and exploring its relation to both age and body site/UVR exposure.
