[Evaluation of skin pH in normal population and its relationship with age, sex and anatomic location]

Everal studies have been conducted to evaluate skin pH in various diseases, but there are few reports in normal population. The aim of this study was to evaluate skin pH in healthy individuals. Fifty healthy volunteers were enrolled in this study. The subjects were divided by age into 5 groups, i.e., 10-20, 21-30, 31-40, 41-50 and 51-60 years old. In each group, 5 females and 5 males were examined. A pH meter [Courage and Khazaka electronic GmbH, Germany] was used to measure pH in 8 different locations of the body [forehead, cheek, nasolabial fold, neck, forearm, dorsal side of hand, palm and leg]. The mean values for pH in these locations were 5.25, 5.15, 5.06, 4.90, 4.75, 4.80, 4.69, and 4.83 respectively. pH was significantly higher in women [P<0.001]. There was a significant difference between skin pH in different age groups [P=0.002]. The highest and lowest amounts of pH belonged to the forehead [5.26 +/- 0.68] and leg [4.69 +/- 0.40], respectively. Age and sex and location have remarkable effects on skin pH
