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

Abstract

These results indicate that the age-related increase in SLEB grade at highly sun-exposed body sites might be attributed to UVR exposure. The presence of SLEB in both the young and at the sun-protected buttock points to a multifactorial etiology, where anatomical differences may play an important role as well as water content. SLEB might not be a very sensitive and specific marker of photoaging.
