Hydration, transepidermal water loss, pH and skin surface parameters: correlations and variations between dominant and non-dominant forearms

Summary The aim of this study was to examine differences between the skin of both forearms with regard to several parameters: hydration (skin capacitance), transepidermal water loss (TEWL), pH and skin surface parameters. Possible correlations between measurements were investigated. Thirty‐three healthy women (32.6 + 8.4 years) participated in the study. The different parameters were measured on each volar forearm (dominant and non‐dominant) at precisely delineated sites. TEWL and developed length (DL) were significantly increased on the dominant forearm (P
