We conducted a systematic review and meta\u2010analysis to provide detailed information on baseline values of SC hydration in healthy human adults, according to the skin area, age and sex. The databases Medline, Embase, Web of Science and Scopus were searched for primary reports, with\n                    <jats:italic>in\u2009vivo<\/jats:italic>\n                    corneometry measurements, which were conducted on disease\u2010free skin of human subjects, aged 18+ years in English. Risk of bias was evaluated using the critical appraisal tools for JBI Systematic Reviews, and only low\u2010risk studies were selected. The comparison was performed in each skin area between males and females and also between young\u2010 and middle\u2010age subjects. Among 323 Retrieved titles, full texts of 259 articles were read, and 240 studies were excluded due to unclear or insufficient reporting of SC hydration, as well as high or medium risk of bias. 19 studies (including 113 records) providing data about SC hydration in 12 skin areas were included in the final data synthesis. Pooled sample sizes ranged from\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200932 for lips to a maximum of\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u20093202 for cheeks. The lowest hydration of 12.5 [95% CI 11.05\u201313.94] was reported for the back, and the highest hydration of 64.34) [95 CI% 62.07\u201364.59] for the periorbital area. Facial skin showed higher water content compared with other areas. There were also site\u2010dependent differences in the hydration level of the facial skin. Comparisons between two age groups, and male and female participants, did not show any statistically significant differences. The main limitation was we included studies using only one measurement device. The quality of reporting SC hydration in humans should be increased in future studies.\n
