The stratum corneum at the post-auricular region is uniquely organized. To understand any differences in efficacy achieved by TCI via bandaid as related to anatomical placement, skin from the post-auricular region and the nape of the neck on chinchillas was collected and the organization of the cells within the stratum corneum examined by microscopy.106 (A) The corneocytes at the post-auricular region were linearly aligned whereas (B) at the nape, a classic ‘brick-and-mortar’ arrangement was observed. Insets, visualization of cell stratification with cellular junctions traced. Scale bars, 10 μm.
