Infant Skin Barrier, Structure, and Enzymatic Activity Differ from Those of Adult in an East Asian Cohort

Figure 2

In vivo confocal laser scanning microscopy revealed structural differences between adult and infant skin beneath the skin surface. Representative images are shown acquired on the thigh area and at different depths representing different epidermal layers. The images at 5 μm show the layer where the first granular cells appear, immediately below the brightly scattering SC. Infant skin appeared to possess denser microrelief lines close to the skin surface (images at 5 and 10 μm) and denser and more uniform dermal papillae (observed at depths 45 and 85 μm) compared to adult skin.
